Edited by Mypinkphone, Six Degrees, Sondra C, Eric and 16 others

Audacity is a robust, powerful open-source audio recorder and editor that can do much more than

you would imagine from a free application. Its interface is a little cryptic in places, so you mayfind yourself a little overwhelmed when you first use it.

Method 1 of 4: Recording

1.1

Connect your gear.In your instrument preferences, set the output destination of yourinstrument. Set the input of Audacity to match the output from your instrument. In this

example, the signal is routed through the Soundflower interface from a software synths

output to Audacitys audio input.

o While sound cards and interfaces vary, its a good practice to monitor your actualinstrument to prevent latency issues. Because latency is always a factor when

monitoring the recorded signal, its very difficult to find your groove whenplaying. In Audacity, set your preferences as shown:

2.2

Confirm connection.Check to make sure your outputs and inputs are properly routed by

first selecting Start Monitoring from the popup menu below the input meters (by themicrophone icon), then playing your instrument.

o The LR input meters should respond.o If the meters are hitting 0dB, use the Input Volume Sider to lower the input level

so that the meters only approach 0 during the loudest sections.

3. 3Choose how to activate recording.When everything is connected properly, and yourlevels are set, youre ready to record. Youhave two options:

o Press Record and start playing. There will generally be some silence at thebeginning of your track. This can be trimmed away when youre done recording.

o Alternately, you can enable Sound Activated Recording in your Recordingpreferences. Check the Sound Activated Recording checkbox, then set the SoundActivation Level (DB)the lower the number, the quieter the sound that willtrigger recording. This is useful if, for example, you are recording in another room

and dont want to have a long silence at the beginning of your track as you walk

back and prepare to play.

4. 4Record your track.Whichever method you choose, its now the moment of truth! Pressthe red Record button (or press R, and when youre ready, start playing. Youll see the

waveforms written to your track as you play.

o Note: While this should not generally be the case, if everything is set as describedabove, if you are flat-lining (i.e., the waveform displays as a straight line) when

you record, that means that signal is not getting from your instrument to yourtrack. Confirm your connections and try again.

Stop recording.When you are finished, press the square yellow Stop button. You should

see something similar to the image above.

o If you chose Sound Activated recording, Audacity will automatically stoprecording when the sound drops below the threshold level.

o To add additional tracks while listening to previously recorded tracks, make sureOverdub: Play other tracks while recording new one is checked in Preferences:

Recording.

6. 6Set a date and time to record.Theres an alternate recording option that most software

sound recorders do not have, and that is Timer Record.

o From the Transport menu, select Timer Record..., or press Shift-T. In the resultingwindow, you can set the Start Date and Time, and either the End Date and Time,

or the Duration. This lets you set your recorder to turn on when you are not

around. Why would you do this? Because you can!

7. 7Extend your recording.If you want to add additional material to your existingrecording, press Shift-Record, or type Shift-R, and new material will be appended at theend of the existing recording on the current track.

Method 2 of 4: Playback

1. 1

5/10

Review your recording.When you have finished your tracking, give it a listen. Click on

the triangular green Play button (or press the Space bar). Your track should play from the

beginning, and will automatically stop at the end of your track.

o Pressing Shift while you press Play or the Space bar will loop your track until youclick the Stop button or press the Space bar again.

o To loop a specific section, make sure the Selection Tool is enabled, then click anddrag over the section you want to loop. Note: after you make your selection, press

Z for the software to automatically find the zero crossing point: the point wherethe start and end waveforms are at 0 amplitude (start and end at at the same sound

level). Depending on the nature of the loop and the source material, this will often

give you a very clean loop without clicks or pops.

2. 2Change the playback speed.You can alter the playback speed easily, which can come in

handy if you are working out a solo, or trying to learn a difficult piece of music.

o Drag the Playback Speed slider to the left to slow the track down, or to the right tospeed the track up, then press the green Playback at Speed arrow to play yourtrack back at the new speed. To make changes, adjust the speed and click thearrow again.

3. 3Choose your view of the track.The default view is the waveform viewed in linear form.Without going into detail, the linear scale is viewed as a percentage of level between 0

or silence; and 1, or maximum level. You can also view the track in other formats:

o Waveform (dB) which shows the waveform in decibel levels. It will generallyappear larger than the linear view.

o Spectrogram, which is a colorful FFT (fast Fourier transfer) view of the audio.

o Pitch, which shows pitches from high at the top of the track, to low pitches at thebottom. Its very interesting with rich textures, and chords.

Solo tracks.If you have multiple tracks playing, and only want to hear one of them, click

on the Solo button in the Track control area to the left of the waveform.

o All other tracks except those that are soloed will be silenced. This is very useful ifyou want to, for example, get a good level between the bass and the drums.

5.5

Mute tracks.If you have multiple tracks playing, and want to silence one or more ofthem, click on the Mute button in the Track control area to the left of the waveform.

o All other tracks but the muted track or tracks will still sound. This is very useful ifyou want to, for example, compare 2 takes, or thin down the mix temporarily.

6. 6Set your pan and level.The Pan control will place your sound in the stereo field, fromleft to right, to any point in between. The level control sets the volume for that track.

1. 1Trim your track.If youve recorded more than you need, to save editing time, trim yourtrack to only what you intend to keep. Start by making a safety backup in case things go

awry, and then proceed as follows:

o Choose the Selection Tool from the toolbar. Select the audio you want to keep.Choose Loop Playback (Shift-Space), and listen to your edit a few times to make

sure its good. Adjust as necessary until it sounds right, then from the Edit menu,select Remove Audio, then select Trim, or simply press Command-T (Control-T

on a PC). The audio on either side of the selection is removed from the track.

o After trimming, move your audio, if necessary, to the correct location by selectingthe Time Shift tool, and dragging the sound to the proper location.

2. 2Apply effects.You can apply a variety of effects, from those built into Audacity, to VST

effects, and effects native to your OS.

o With the selection tool, select all or part of your track.o From the Effect menu, choose your desired effect. For this example, well use

Echo, as applied to a simple click track.

9/10

o Set any parameters called for by the effect, listen to the preview, and when itshow you like, press OK. The effect will process, and display the result. Theexample below is the raw click track on top, and the echoed click track on the

bottom.

o You can process the same track with many effects, though its possible to amplifythe waveform too much, resulting in ugly digital distortion. If that happens, undoto the last step before distortion kicked in, and instead of applying your next filter,

apply an Amplifier effect, set to -3dB. If your next process still results in

distortion, undo the distorting effect and the Amplify effect, then redo theAmplify effect at a stronger level. -6dB would be good.

10/10

o Note: Its always a good idea to duplicate a track (Command or Control-D) beforedoing any editing that changes the waveform.

3. 3Experiment freely.Try all the filters, and see what they do and how the sound with your

source material.

4.4

Save your finished sound file.When youre done editing, mixing, trimming, and

polishing your sound file into a rare gem of musical beauty, you will want to save it forposterity and possible fame and fortune. From the File menu, select Export..., then choosethe desired formatfrom AIFF to WMA and many others in between.

Method 4 of 4: Dig In

1. 1Audacity may be free, but its an immensely powerful sound application. Its loadedwith great effects, sound generators, and a fairly flexible editing system. Once you get the

hang of how it feels, youll be able to turn out some great stuff.
