noise Removal
- Cleans up noise from a recording . First, select a small piece of
audio that is silent except for the noise, select “Noise Removal”, and click on the
“Get Noise Profile” button . Then select all of the audio you want filtered, select
“Noise Removal” again, and click the “Remove Noise” button . You can experiment
with the slider to try to remove more or less noise . It is normal for Noise Removal
to result in some distortion . It works best when the audio signal is much louder
than the noise .
normalize
- Allows you to correct for DC offset (a vertical displacement of the
track) and/or amplify such that the maximum amplitude is a fixed amount, -3 dB .
It’s useful to normalize all of your tracks before mixing . If you have a lot of tracks,
you may then need to use the track gain sliders to turn some down .
nyquist Prompt
- Allows you to express arbitrary transformations using a powerful
functional programming language . See the Nyquist section of the Audacity website
for more information .
Phaser
- The name “Phaser” comes from “Phase Shifter,” because it works by
combining phase-shifted signals with the original signal . The movement of the
phase-shifted signals is controlled using a Low Frequency Oscillator (LFO) .
Repeat
- Repeats the selection a certain number of times . This operation is quite
fast and space-efficient, so it is practical to use it to create nearly-infinite loops .
Reverse
- This effect reverses the selected audio temporally; after the effect
the end of the audio will be heard first and the beginning last .
