In audio recording, a compressor limits the input above a certain volume. A multi-band compressor does the same, but only to specific frequencies, not to the whole audio channel. For instance, you can use this to even out the low notes and make the bass more constant, or to select out stray sounds, to clean up vocals, fix bad drum noise, or add umph to your mid-ranges. You can make these changes without having to select out entire frequency ranges, the way you would with an equalizer. Otherwise, you can play with all the other settings you find with regular compression: attack, ratio, release, etc.
- A multiband compressor will allow the user to specify what frequency to compress.
- An experienced audio tech can us a multiband compressor can be used to control gain.
- A conservative configuration in your compressor is the best way to start.
