About this audio compressor
A compressor reduces the gap between the loudest and quietest parts of an audio track. The result sits at a more consistent level — easier to listen to in the car, on a phone or through earbuds. Every podcast, broadcast and pop song you've ever heard has been compressed.
Pick a preset for the common cases (Voice, Music, Heavy) or roll your own threshold and ratio.

Compressor FAQ
What does threshold mean?
The volume above which compression kicks in. Lower threshold = more material gets compressed. -20 dB is a typical voice setting; -10 dB is gentler.
What's a good ratio?
Ratio is how aggressively material above threshold is squashed. 2:1 is gentle, 4:1 is firm voice-over, 8:1+ is broadcast/pop. Above 10:1 you're effectively limiting.
Will it sound pumpy?
If you push attack/release wrong it can. The Voice and Music presets pick conservative timings; the Heavy preset is intentionally aggressive.
Will the audio be re-encoded?
Yes — compression requires re-encoding. The output uses the same format as the input at a sensible quality default.
