Add Label at Playback Position - This menu item lets you create a new label at the current location
where you are playing or recording. Do this if you want to mark a certain passage while you're
listening to it. You can title the label by typing with the keyboard and then hitting "Enter" or
"Return" when you're done. Only available whilst audacity is playing.
Generate Menu
If you choose an item from the Generate menu when there are no tracks in a project, a new track
is created. Otherwise, the current track is used. If a track is selected and the cursor is placed in a
single place in the track audio is inserted at the cursor position. The default duration is 30 seconds.
The audio created will replace the any selection, otherwise it is inserted into the track, shifting up
later parts of the track.
Silence - inserts silence
Tone... - you can create a Sine wave, Square wave, or Sawtooth wave.
White Noise - inserts random audio samples, which sounds like pure static.
Any items which appear after these three built-ins are VST, Ladspa, or Nyquist plug-ins. It is
possible for a poorly written plug-in to crash Audacity, so always save your work before
using a plug-in. Note that any effect that doesn't take any audio as input will automatically
be placed in the Generate menu.
Effect Menu
The items in this menu only work when you have audio selected. Audacity does not have any real-
time effects; you must select the audio, apply the effect, and then listen to the results. Most
effects have a Preview button. Clicking on this button plays up to three seconds of audio, allowing
you to hear what it will sound like after the effect is applied. This is useful for fine-tuning the effect
parameters.
Repeat Last Effect - selecting this command is a shortcut to applying the most recent effect with
the same settings. This is a convenient way to quickly apply the same effect to many different
parts of a file.
Amplify - changes the volume of the selected audio. If you click the "Allow clipping" checkbox, it
will let you amplify so much that the audio ends up beyond the range of the waveform, and is
clipped (distorted). The default value when you open the effect is to amplify so that the loudest
part of the selection is as loud as possible without distortion.
Bass Boost - enhances the bass frequencies in the audio.
