Parametric EQ

In a parametric equalizer, each filter cuts or boosts a range of frequencies. Each filter has three controls:
Frequency: the center of the frequency range to be cut or boosted
Gain: the amount of boost or cut
Q: the "sharpness" of the boost or cut, with higher Q meaning a narrower filter

Peak Limiter

The Peak Limiter automatically adjusts volume so that incoming audio never rises above a 0 dB limiting threshold.

Time Pitch

In music the pitch of a note means how high or low a note is.
