Listening to a recording
Editing an audio signal (optional)
i
In the "Effect" menu you will find a series of functions with which you can
edit your recordings. This allows you to change the volume ("Amplify"),
balance deviations in volume ("Normalize...") or fade recordings in or out
("Fade In" or "Fade Out"). You will find further information about the
individual effects in Help in Audacity or
at http://audacity.sourceforge.net.
When records are converted to digital files a certain amount of background noise
is also digitalised, e.g. the crackling and hiss of older records in particular.
Audacity helps reduce these background noises.
Removing noise
2. Select "Noise removal..." in the "Effect" menu. The "Noise Removal" window
appears.
• Click on the playback button to play back the
recording. The playback is controlled via the
buttons in the menu bar.
1. Mark with the cursor an area in your recording in
which there is no music but only background
noise heard. Areas between the tracks of a long
playing record are especially suitable for this.
3. Click on "Get noise profile". The window closes
and Audacity creates a noise profile with the
background noises that are to be removed.
