This one might seem a little easy for some people, but it essential that everyone knows it – what is a compressor, and how to use compressor plugins in protools.
Basically a compressor takes the incoming audio and squeezes it, making the louder bits quieter and the quieter bits louder. You have control over how much compression you add to incoming audio. There are four main controls on a compressor – threshold, compression ratio, knee, attack and release.
