Complete Guide: Audio Compressor
Everything you need to know about using this tool effectively
The Audio Compressor reduces the dynamic range of your audio files. Quiet sounds become louder while loud sounds stay at their peak level. This creates more consistent volume throughout your audio, making it easier to listen to in different environments.
This tool uses the Web Audio API to apply dynamic range compression to your audio. A compressor listens for sounds above a certain threshold and automatically turns them down. This reduces the difference between the quietest and loudest parts of your audio.
Podcast production
Compress podcast audio so quiet narration and loud laughter are balanced.
Music production
Add punch and consistency to drums, vocals, and full mixes.
Video voiceover
Even out voice levels for consistent listening in videos.
Live recordings
Tame inconsistent volume in live concert recordings.
Audiobook processing
Create consistent volume levels throughout long audiobook recordings.
Broadcast prep
Prepare audio for broadcast with proper dynamic range for different playback environments.

Start with a moderate ratio (2:1 to 4:1) and adjust threshold
Use makeup gain to bring overall volume back up after compression
Fast attack times affect transients - use carefully on drums
Less compression often sounds better than more
Heavy compression can make audio sound squashed - use sparingly
Listen at different volumes to check the compression effect
What does a compressor do?
A compressor reduces dynamic range by turning down sounds that exceed a threshold. Quiet parts stay the same while loud parts get quieter, creating more consistent volume.
What is a good compression ratio?
2:1 to 4:1 is gentle and natural. 8:1 and above is heavy compression. Start gentle and increase if needed.
Does compression affect audio quality?
Light compression is transparent and improves consistency. Heavy compression can sound squashed and lose impact.
Is my audio file uploaded to a server?
No. All processing happens in your browser using the Web Audio API. Your files never leave your device.
What is makeup gain?
Makeup gain boosts the overall volume after compression brings down the loudest parts. It restores lost loudness.
What is the threshold setting?
The threshold sets the volume level where compression starts. Sounds above the threshold get compressed, sounds below stay unchanged.
