The University of Sheffield, 5 Favell Road, Sheffield, S3 7QX, jibticutepo.gq uk/lets. Version 3: April 1. Step by step guide to using Audacity. Contents. Audacity Manual. 1. GETTING STARTED. Creating a new project. •. Open Audacity, select New and under the File menu select Save Project As. •. Give the . This tutorial: jibticutepo.gq 2. Open Audacity. You should now see the (empty) Audacity project workspace.
A Playback speed slider, with values up to , which corresponds to 3 times the normal playback speed. The effects of this setting are: If checked, then when you change the value of the playback speed slider during play at speed, it has immediate effect.
However, during playback, the seek commands described above have no effect. If not checked, then changes to the value of the playback slider during play at speed have no immediate effect.
However, the seek commands work as normal. Toolbars The Toolbars section contains several different toolbars. These are the toolbars which are shown by default: This contains buttons for playback and recording, and all the commands are also available on the Transport menu, and have keyboard shortcuts. This contains tool buttons for editing which involve the use of the mouse.
Recording meter and Playback meter. Each of these contains a drop down button which opens a menu for controlling the meter.
This contains the recording and playback volume sliders. This contains buttons for Cut, Paste, etc. These commands are also available on either the Edit or View menu, and all have keyboard shortcuts. Play at speed , which contains a play at selected speed button and a playback speed slider. This contains combo boxes for Audio host, the recording device, the number of recording channels, and the playback device.
Note that if one of these combo boxes is the focus, and you press a character key which is an Audacity shortcut, then the key is used for the shortcut, rather than selecting an option beginning with that character. So selecting an option using its first character is not recommended. In addition, if you start playback or recording, then the focus is then automatically moved to the Track table. Track table The Track table contains the tracks which make up the project.
Track focus Whenever the focus is within the track table, and the table contains one or more tracks rows , then one of the tracks has the focus, and you can move to the next or previous track by pressing Down Arrow or Up Arrow , respectively. Track selection You need to be able to select tracks: For operations such as aligning tracks which can be found on the Tracks menu. As part of the process of selecting some audio, as described in the Selecting audio section. There are a number of ways of selecting and deselecting tracks: To toggle the selection of the focused track, press Enter.
Jaws tells you whether a track is selected, if you do any of the following: Move the focus to the track. Toggle the selection of the track, by pressing Enter. Project Rate edit-combo box. This is the sampling rate of the project. Snap To combo box, which is described below. Audio Position edit spin box. This gives the position of playback or recording. A Show combo box which determines which details of any selected time range are shown in the two edit spin boxes, which are the next two controls in the toolbar.
The options for the details which are shown are: Two edit spin boxes, which give the details of the selected time range, which have been specified by the preceding combo box. If there is no time range selected, then the start, end, or center edit spin boxes give the position of the cursor. Edit spin boxes Each of the spin boxes contains a time which can be in a number of different formats. The keystrokes for moving the focus are: Home or End move you to the first or last digit in the spin box respectively.
Left Arrow or Right Arrow cycle you through the digits to the left or right respectively. There are a couple of ways of changing the value of the time: Increasing or decreasing the value of the control by one unit of the focussed digit using Up Arrow or Down Arrow.
This is a way is useful for increasing or decreasing the value by a given amount of time. After each of these keystrokes, Jaws reads the value of the current section. For example, if you want to increase the time by 3 tenths of a second, and assuming that the format is set to hh: Type in digits. This way is useful for setting a time which not connected to the current value.
If you type a digit 0 to 9 , then the value of the focussed digit is replaced by this, and the next digit becomes the focus. If the last digit is the initial focus, then after you type a digit, then the first digit is the focus. After typing a digit, Jaws reads the section containing the focussed digit. For example, if you want to set a control to 32 minutes, and again assuming the control has the hh: This completely replaces the existing time with the time of 32 minutes. Snap To combo box The Snap to combo box contains three options: Moving the cursor Audacity has a cursor to specify a particular time during the audio, for example, the start of playback, the position where you want to start selecting a time range, or the position where audio is pasted from the clipboard.
Reading the current position of the cursor is described in the next section, and the ways of moving the cursor are as follows: To move the cursor to the start of the tracks time zero , press Home. To move the cursor to the end of all the audio, press End. To move the cursor to the start or end of the audio in the selected tracks press J or K respectively.
You can move backward or forward by either a short or long period, as long as the focus is in the Track table. To move backward or forward by a short period, press Comma or Period respectively. Left Arrow and Right Arrow keys. If the focus is in the Track table, then pressing Left Arrow or Right Arrow moves the cursor to the left or right by a small amount respectively. Adjusting the step size is described in the Step size of the left an right arrow keys section below.
The [ key during playback. If during playback you press [ and then Spacebar to stop, the cursor is moved to the point in the audio where you pressed the [ key. In practice, the following method is more flexible: During playback, press P to pause when you reach the position where you want to move to cursor to.
Press [ to mark the new cursor position.
Press Spacebar to stop. Pressing X stops playback, and moves the cursor to the position where the playback stopped. You can also use this keystroke to start playback. The Start of selection spin box on the Selection bar. This is described in detail in the Moving the cursor with the Start of selection control section below.
Reading the position of the cursor There are a couple of ways of reading the cursor position. The first is to read the Start of selection control on the Selection bar: If necessary, Tab until you get to the Start control, which contains the cursor position, and which Jaws reads out. Note that when returning to the Selection bar, the control that was previously the focus is the focus again, so you often don't have to Tab to the Start control.
The second way of reading the cursor position is to open the Set left selection boundary dialog: Whilst there is no playback, press the [ key to open the Set left selection boundary dialog. The position control is the initial focus, and its value is the cursor position.
Press Esc to close the dialog. Tab to the Show box, and make sure that the Start and length of selection option is selected. If it's set to Start and end of selection, then you can accidentally select a time range, instead of moving the cursor, as described below. Tab to the Start control, and change its value, as described below. As described in the Edit spin boxes section , there are a couple a ways of changing the values of the controls like the start control: Incrementing or decrementing the value of the control by one unit of the focussed digit using Up Arrow or Down Arrow.
For example, to move the cursor forward by 2 minutes, assuming that the format is set to hh: Typing in digits. For example, to move the cursor to the time 45 minutes, again assuming the format is set to hh: Reason for setting the Start and length of selection option With no time range selected, consider the two cases: The Show combo box set to Start and length of selection. The start control displays the cursor position, and the length control displays zero.
If you change value of the start control, then the length control always remains unchanged at zero. The Show combo box set to Start and end of selection.
The start and end controls both display the same value, which is the cursor position. If you increase the value of the start control, then the value of the end control is automatically increased to the same value.
However, if you decrease the value of the start control, then the end control remains unchanged. So you've accidentally selected a time range. Step size of the left and right arrow keys This section describes how the step size of the left and right arrow keys depend on the horizontal zoom of the audio data, and how to set the amount of zoom so that the step size has suitable values.
However, you can easily adjust the step size using the zoom in and zoom out commands which are also available on the Zoom sub menu on the View menu: This doubles the zoom, and so halves the step size of the left and right arrow keys.
This halves the zoom, and so doubles the step size of the left and right arrow keys. Selecting audio In the case of an audio editor which can only edit a single audio track, then selecting audio simply consists of specifying the start and end times of the audio which you want to select, that is, a time range.
The first general way of selecting a time range consists of two steps: Move the cursor to where you want to start or end the selection, using one of the methods described in the Moving the cursor section above. Set the other end of the selection using one of the methods described below. You can use any of the following methods for setting the other end of the selection: Set the end of the selection using the ] key during playback.
If during playback you press ] and then Spacebar to stop, the end of the selection is set at the point in the audio where you pressed the ] key. During playback, press P to pause when you reach the position which you want to be the end of the selection.
Press ] to mark the position for the end of the selection. Using the selection controls on the selection bar, as described in the next section. Note that Track table must be the focus to use these keystrokes. Setting the start or end of the selection using the selection controls With the cursor positioned where you want to start the selection, to set the end of the selection: Tab to the Show combo box, and set it to either start and end of selection, or start and length of selection.
If you increase the value of either the length, or the End control, then the value of the start control remains unchanged at the initial cursor position.
Tab to the end or length control. If it's the End control, then increase its value. For example if you want to move the end of the selection to five seconds after the start of the selection, and assuming the format is set to hh: If it's the Length control, then you can increase the value of the length by either by using Up Arrow , or by typing in digits, as described in the Edit spin boxes section, which is in the Selection bar section.
With the cursor positioned where you want the end of the selection, to set the start of the selection: If you increase the value of either the length, or the start control, then the value of the end control remains unchanged at the initial cursor position.
Tab to the start or length control. If it's the start control, then decrease its value. For example, if you wanted to move the start of the selection to ten seconds before the end of the selection, and assuming that the format of the selection controls is set to hh: Selecting a time range using the stored cursor position The second general method of selecting a time range consists of four steps: Open the Select menu, and choose Store Cursor position. Set the other end of the selection, again using using one of the methods described in the Moving the cursor section above.
Open the Select menu, and choose Cursor to Stored Cursor position. Playback commands for checking a selected time range When a time range is selected, then if you press Spacebar for playback, only the audio in the selected time range is played. In addition you can use the following playback commands to check that you've selected the time range which you want: To play a cut preview, press C.
This plays back a short period before selection start, and then a short period after selection end. The selected time range itself is omitted. Adjusting a selected time range There are a couple of ways of making small adjustments to a selected time range, and they are described in the next two sections. Adjusting the selected time range using keystrokes to move the start or end of the selection You can use the following keystrokes to move the start or end of the selection by a small amount.
Tab to the Show combo box, and set the Start and end of selection option.
This allows you to adjust the Start or the End of the selection without affecting the other one. Tab to either the start or the end control. If the format isn't already set to hh: The format can be changed using the context menu of the control. If, for example, you want to adjust the time in tenths of a second, press End to move to the last digit, and then press Left Arrow to move to the tenths of a second digit.
You can then press Up Arrow or Down Arrow to increase or decrease the time by a tenth of a second respectively.
Adjust the other selection control if desired. Deselecting a selected time range If you press any of the following keystrokes which move the cursor, then any selected time range is deselected: Deleting audio To delete the selected audio, press the Delete key. There are two cases: If a time range is not selected, and so no audio is selected, then the audio is inserted at the position of the cursor. If some audio is selected, the selected audio is replaced by the pasted audio.
There are a couple of convenient playback commands which can be used for checking that the transition at the start and end of the pasted audio sounds alright: Insert silence To insert a period of silence into the selected tracks: Move the cursor to where you want to insert the silence.
Choose Silence from the Generate menu. A Silence Generator dialog opens, and the focus is a spin box which allows you to specify the length of the silence.
The spin box is identical to the spin boxes used on the Selection bar, though the first non-zero digit is the initial focus, rather than the first digit. Effects Audacity provides a large number of effects which are available on the Effects menu. Effects with real-time preview Some of the effects which can be used Audacity include real-time preview — where you can change the settings of an effect during playback.
The dialogs of effects which include real-time preview include the following controls, all of which have access keys: Apply button, which applies the effect to the selected audio, and is the dialog's default button. Note that as with any other Apply button, it doesn't close the dialog. Close button Esc.
Manage button. This opens a menu which includes commands for presets, and opening an options dialog. If you press Stop Playback during playback, and then press Start Playback, then playback resumes from where it was stopped.
Skip Backward button. During playback, pressing this seeks backward by a short period. Otherwise, pressing it ensures that the next playback starts at the start of the selected time range. Skip Forward button. During playback, pressing this seeks forward by a short period.
Otherwise, pressing it causes the next playback to start at the end of the selected time range. Enable check box. This sets whether the effect is enabled, and is checked by default. Unchecking this allows you to quickly compare the audio with and without the effect. To delete the selected track or tracks, choose Remove Tracks from the Tracks menu.
Avoiding introducing clicks when editing If you delete or cut part of the audio in a track, and if the beginning or end of this part hasn't zero amplitude, then this can result if sudden changes in the amplitude of the audio.
So to avoid introducing clicks: After selecting part of the audio in a track, and before cutting, deleting or copying, apply the At Zero Crossings command. After you've positioned the cursor for pasting audio into a track, and before pasting, apply the At Zero Crossings command. More advanced editing Adding a new empty track To add a new empty track, choose an option from the Add New sub-menu which is on the Tracks menu. Importing audio files You can import one or more audio files, and these become new tracks in the existing project.
Align the audio in tracks end to end If you select two or more tracks, you can align the audio in these tracks so that the audio in a track starts at the end of the audio in the previous track. The order in which the audio in the selected tracks is aligned is the same as the order of these tracks in the track table. If you need to change the order of the tracks in the table, you can do this using commands on a track's track menu. The position of the audio in the first selected track remains unchanged.
Time shift You can time shift the audio data in one or more selected tracks so that either the start or the end of the audio is at some desired position. There are a couple of convenient playback commands which can be used for checking the position of the shifted audio: Examples To move the audio in one or more tracks so that it starts at some desired time: Move the cursor to the desired time, using any of the methods described in the Moving the cursor section.
Select the tracks containing the audio you want to move, and make sure that the other tracks are not selected. Note that if more than one track has been selected, and the audio in these tracks start at different times, then the audio in all the tracks is moved by the same amount, so that the earliest audio in the tracks is positioned at the cursor.
As another example, if you want to time shift one or more tracks by a certain amount of time, then: Select one or more tracks that you want to time shift, and make sure that the other tracks are not selected. Press J to move the cursor to the start of the audio in the selected tracks.
Make sure that the start and length option is selected. Tab to the Start spin-box. Depending on whether you want to time shift forward or backward, you now need to move the cursor forward or backward by incrementing or decrementing the time in the spin-box.
For example, if you want to move the audio forward by 1. End moves you to right most digit, which is hundredths of seconds; Left Arrow moves you to the tenths of second digit; Up Arrow five times increments this digit by five; Left Arrow moves you to the seconds digit; and finally, Up Arrow increments this digit by one.
This moves the data in the selected selected tracks, so that is now starts at the modified cursor position. Moving a track On the Track menu there are commands for moving a track up, down, to the top, and to the bottom of the tracks.
Track Mute and Solo Each track has a mute setting which can be on or off, and a solo setting which can also be on or off. Mute If a track's mute setting is on, then it doesn't contribute to playback, or to the audio saved in one of the standard formats.
You can either change the mute setting of an individual track or the settings of all the tracks: Solo If one or more tracks have their solo setting on, then only these tracks contribute to playback, regardless of the Mute settings of all of the tracks. There are a number of options for the solo setting and its interaction with the mute setting: Simple, which is the default. If you turn off the solo setting of a track, then for all the remaining tracks, the mute setting is turned off.
The mute and solo settings are completely independent. There's no solo setting, just a mute setting. Sync lock tracks The idea of sync-lock tracks is to try and keep a group of tracks time synchronized with each other when some operation, such as deleting, affects the timing of one or more tracks in the group.
Labels A label represents either a specific time position or a specific time range, and it can have a name. Creating labels There are two commands for creating labels, and both are on the Labels sub menu on the Edit menu: With no time range selected, this creates a point label for the position of the Cursor. If there is a selected time range, then it creates a region label for the time range. First, using a dialog box for the name: Either choose one of the commands from the Labels sub menu on the Edit menu, or press its shortcut.
A New label dialog opens, and a name edit box is the initial focus. Type in a name for the label optional , and then press Enter to press the OK button, which is the dialog's default button. The new label in added to a label track, which is the first of the following possibilities: The focus is returned to the original track.
To use these commands for adding labels, not using the dialog option: Either choose one of them from the Labels sub menu of the Edit menu, or press its keystroke. If the focused track isn't a label track, then the first label track below this track becomes the focused track, if such a track exists. If there isn't one, a new label track is appended to the existing tracks, and becomes the focused track. In the focused label track a new label is created, and an edit box is opened for entering a name for the label.
Unfortunately Jaws does not say that the focus is now this edit box. Type in a name for the label optional , and then press Enter to close the edit box. For the Add label at Playback position command, the focus is then returned to the original track. Moving to labels There are two commands for moving to labels. This moves to the nearest label after the cursor, or the start of a selected time range.
If there's no label after this time, then it wraps round to the first label. This moves to the nearest label before the cursor, or the start of a selected time range. If there's no label before this time, then it wraps round to the last label. Editing labels The uses of the Edit labels dialog include renaming a label, deleting a label, and as an alternative to the move to label commands.
The dialog includes the following controls: A table which contains details the labels in all of the label tracks in the project, and which is described in the next section. Insert before, Insert After, and Remove buttons which can be used for editing the table. Import and Export buttons for importing labels from and exporting labels to a text file. In determining which name is selected, the position of a region label is taken as the start of its time range: If the cursor, or the start of a selected time range is at the position of a label, then the name of that label is selected.
Editing in Audacity - Quick Intro
Otherwise, the name of the label which is the nearest label before this time is selected. If there is no label before this time, then the name of the first label is selected. The table The table has six columns: There are a number of ways of selecting a cell in the table: To select the next cell in the table, press Tab or Right Arrow.
If the last cell is selected, pressing Tab moves you to the next control, which is the Add button. To select the cell directly below or above the current cell, press Down Arrow or Up Arrow respectively. Deleting a label Select any of the cells in the row representing the label.
There are then two alternatives. Editing cells Jaws reads all the cells as if they were edit boxes. Editing the name of the label You can either overwrite or edit the current name: To overwrite the current name, simply type in some text, and then press Tab or Enter to confirm the edit, or Esc to cancel the edit.
To edit the existing name, press F2 , which selects the existing text. To deselect the text before editing, press Right Arrow or End which positions the current character immediately after the existing text, or press Home which makes the current character the first character in the text.
To confirm the edit press Tab or Enter , or to cancel the edit press Esc. Editing the start or end time Press F2. You can now edit the time in exactly the same way as you can edit the time controls such as Selection start in the Selection bar.
Clips In most of the rest of this guide, it has been assumed that an audio track contains a single section of audio data. There are a number of ways you can end up with more than one clip on a track: When you record with the audio being appended to an an existing track, then the recorded audio is added as a separate clip. The use of various split commands, which are described below.
Paste some audio into a track which already contains a clip, and at a position which does not lie within the existing clip. Moving the cursor There are commands for moving both to the next and previous clip boundary, where a clip boundary is either the start or end of a clip. Selecting a time range There are two sets of commands for selecting time ranges which involve clip boundaries, and these are described in the next two sections.
Selecting the previous or next clip There are commands for both selecting the previous clip, and selecting the the next clip.
For the Select next clip command: If there is no selected time range, then the first clip which starts either at or after the cursor position is selected. If there is a selected time range, then if the start of the selection is positioned at the start of the clip, and the end of the selection is before the end of the clip, then that clip is selected. Otherwise the first clip which starts after the start of the selection is selected.
For the Select previous clip command: If there is no selected time range, the first clip which starts before the cursor is selected.
If there is a time range selected, then if the start of the selection is positioned at the start of a clip, and the end of the selection is after the end of the clip, then that clip is selected. Otherwise, the first clip which starts before the start of the selection is selected. Selecting using clip boundaries The two commands for selecting using clip boundaries can be used in more cases than the commands for selecting the next and previous clip which were described in the previous selection.
Previous Clip Boundary to Cursor, sets the start of the selected time range to the previous clip boundary. Cursor to Next Clip Boundary, sets the end of the selected time range to the next clip boundary. Various split commands Split To split a clip into two clips in a selected track: Position the cursor where you want to split the clip.
On the Edit menu, open the Split Boundaries sub menu, and choose Split. Split delete, and Split cut You can use the split delete and split cut commands to delete or cut the selected audio, without affecting the position of the contents of the track after the audio which was deleted or cut.
Split New The Split New command moves the selected audio to a new track or tracks, without affecting the position of any subsequent audio in the original track. Detach at silences If the selected audio contains sections of complete silence, that is the amplitude of the audio is zero, then the Detach at Silences command can be used remove those sections of audio, leaving clips which are separated from each other by the resulting sections of empty track.
Merging clips To merge two or more adjacent clips in a selected track: Select a time range such that the start of the time range is before the end of the first clip, and the end of the time range is after the start of the last clip.
So for example, you could arrange for the start of the time range to be the start of the first clip, and the end of the time range to be the end of the last clip. The clips are joined together, and any space between the clips is replaced by silence. Time shifting clips There are a couple of commands, Clip Left and Clip Right, which can be used to move either a single clip, or a number of clips.
Moving a single clip Move to the track which contains the clip which you want to move. Move the cursor so that it lies anywhere within the clip.
If the cursor is at either the start or end of clip, then it it is considered to be lie within the clip, but it's not recommended to use the end of the clip for reasons which are explained below. Clip Left or Clip Right move both the clip and the cursor by a small amount. Moving a number of adjacent clips To move a number of adjacent clips in a track: Move to the track which contains the clips which you want to move. Select the track — the other tracks should not be selected.
You then need to select a time range such that the start of the selection lies within the first clip you want to move, and the end of the selection lies within the last clip. So, for example you could move the cursor to the start of the first clip, and then set the end of the selection to the end of the last clip.
Moving clips when Sync lock tracks is enabled The use of sync-lock tracks to keeps a group of tracks time synchronized was described in the Sync lock tracks section , which in the More advanced editing section. If a clip overlaps in time with a clip in the original set of clips to be moved, then it also will be moved. In fact, the rule is more general than this. For any clip, if there exists a series of clips, starting with this clip and ending with a clip in the original set of clips to be moved such that each pair of adjacent clips in this series overlap in time, then that clip will also be moved.
If there are one or more label tracks in the sync locked group, then all the labels in those tracks will be moved, though it is not clear why this should be the case. Metadata tags editor Metadata is data which describes other data, and the metadata for audio files consists of a number of tags, where each tag is made up of a tag name and a tag value.
The Edit Metadata Tags dialog contains the following controls: A table which contains the names and values of the tags, and is described in the next section. Add, Remove, and Clear buttons which are used for editing the table. Pressing the Clear button deletes all the values of the preset tags, and all names and values of any custom tags.
The Add and Remove buttons are described in the creating and editing custom tags section. A genres section, consisting of Edit and Reset buttons which are used for editing the preset list of genres, as described in the Editing the list of genres section below. A template section, which won't be described in this guide. The table The table has two columns: To select the cell directly below or above the current cell, press Down Arrow or Up Arrow. Editing tag values All the tag values except the genre tag value are edited using an edit box, but the genre tag value is edited with an edit combo box, which allows you to quickly choose from a list of genres.
To overwrite the current value, simply type in some text, and then press Tab or Enter to confirm the edit, or Esc to cancel the edit. To edit the existing value, press F2 , which selects the existing text. If mastering from tape. If you don't have an external them together. Audacity automatically mixes on the right.
Select "Split Stereo while they're playing. Track" from this menu. In audio books. Substitute it with. The first option is a tool. Silence stuff you don't want.
You can combine three ways of handling this: Continuous sound is the key in those cases and having the ambience. The holes you create with it are easier to control and change at later times. Use the envelope tool to create volume automation to pull down those parts.
Speech or Wallas fx made with voices You want to: Therefore filling those holes with material on Therefore the second option is general practice. It allows you to change or take back what you did after you have made those changes to the volume curve with the envelope tool. Then come back here. Be sure to only silence the bits you don't want and don't forget to fade the edges around the silenced material. The second best way is to use volume automation to get rid of any unwanted stuff.
For this reason only silence unwanted audio if it's too obtrusive.
When using the envelope tool. If it doesn't sound good.
With volume automation you can mute sections of the audio without actually making any edits to the audio data. Substitution expands and improves that option. Audacity Manual Title Page material. Use the Silence function instead.
If you're doing things that require critical timing. Just remember. Bad takes are of course not usable. Select that bit and duplicate it. Mute that new track. The speaker might have made a longer pause. This is usually a piece of ambience somewhere else in the audio track.
This will be our filler for the next gap in the original track. Chop By The Numbers: The goal is to split the long audio track in to several smaller tracks. The selection format for the track that contains the audio clip to be split has to be: Splitting tracks for CD burning You can cut it up.
You want to split it up in to parts that you wish to be separate audio tracks on a CD.. The contents of that track will be selected.
Repeat steps 1 and 2 for each track you wish to be on your audio CD Roast.
Repeat steps 1 to 4 as necessary. Audacity Manual Title Page track you're working on. Place the cursor where you'd like the current track to end and the new one to start. Think you know how this could work a lot easier? Do you need additional help or have suggestions on how to improve Audacity? Get Them Ready for Deep Fry: Once all the tracks are created you need to Export each Audacity track that you wish to be on your CD.
Conclusion That was easy. Pick your filename carefully. Check the preferences under "File Formats". You can also select from Start to Cursor instead.
Go to the Edit menu and pick Split. Make sure that no pauses are between those tracks. That's required by the Red Book standard. Click on an empty part of the track panel left of the wave display with the mute and solo buttons of the track you wish to export. Number them accordingly. The only exception is the standard pause before the first track.
Burn and enjoy. I'm not taking the floor into account because of the obstacles. Freeverb unfortunately does not have an Early Reflections feature.
We choose whatever is closest to 15 ms. The band will be playing no more than four meters away from us. Our room the club is about eight meters on all sides for simplicity and three meters high. In Soundforge however there are a few ER times to choose from. First we determine some basics about the room we want to simulate. Experiment and listen very carefully. This is the amount of time we'll need to take off the other values.
The room volume will be about cubic meters. Let's see what we have to do with parameters in the reverb fx in sample editors. Our club has lots of wood on it's walls and floor and people are sitting at tables and the air's probably filled with a little smoke except in California: No parameter like that in Freeverb and yet it sounds great.
Materials such as polished marble will reflect the sound very well and disperse the sound very little.
