Here's just a sampling of the things that you can do with this wild and wonderful tool:
Amplify - changes the volume of the selected audio.
BassBoost - enhances the bass frequencies
Change Pitch - changes the pitch/frequency of the selected audio without changing the tempo. (Can also change speed and tempo.)
Click Removal - removes clicks on recordings from vinyl records without damaging the rest of the audio. You can choose how sensitive the click detection is, and what the maximum length of a click is.
Echo - repeats the selection with a decay, sounding like a series of echos.
Equalization - Boost or reduce arbitrary frequencies. You can select one of a number of different curves designed to equalize the sound of some popular record players, or draw your own curve.
Noise Removal - lets you clean up noise from a recording.
Repeat - repeats the selection a certain number of times.
Reverse - reverses the selected audio temporally; after the effect the end of the audio will be heard first and the beginning last.Wahwah - uses a moving bandpass filter to create its sound.
