Things A Compressor Can Do And When You Can Use It
- Soft Knee settings make the compressor apply compression in an increasing amount until it hits the ratio. It also doesn't wait for the audio to reach the threshold to start compressing. It will get applied gently until it reaches the threshold. This is why it can make the transformation between the uncompressed and compressed audio signal more effortless and less intrusive. Soft knee settings are good for guitars, violins, synths and pianos and instruments that need to sound smooth.
- Hard Knee Settings make every part of your audio single get compressed by the entire amount of the ratio. It will not apply any compression until the audio reaches and passes the threshold, unlike the soft knee setting. This setting makes the compression more intrusive and less smooth. It good for fast peaks, like drums and percussion instruments
