Frequently asked questions
How do I compress audio?
Choose a recording, set the threshold and ratio, then adjust attack and release. Preview and compare with Original before downloading.
What do attack, release and knee change?
Attack controls how quickly compression responds to louder sound. Release controls how quickly it recovers. Knee makes the transition around the threshold gradual or sharper.
Can I raise the level after compression?
Use makeup gain to raise the compressed signal. Prevent clipping can lower the finished audio to leave 1 dB of headroom. Both stereo channels receive the same gain reduction.
