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”
check-box, 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.
Change Pitch
- Changes the pitch/frequency of the selected audio without changing
the tempo. When you open the dialog, the starting frequency is set to Audacity’s best
guess as to the frequency of the selection. This works well for recordings of singing
or musical instruments without background noise. You can specify the pitch change
in one of four different ways: musical note, semitones, frequency or percent change.
