🎧 Compression Simulator
Adjust threshold, ratio, attack and release controls — and hear exactly how each one shapes your audio in real-time. No DAW needed.
🎤 Audio Source
Choose a sound to compress. Each source demonstrates different compression behaviors.
🎛️ Compression Controls
-20 dB
Signal level where compression begins. Lower = more compression.
4:1
How aggressively signal above threshold is reduced.
10 ms
How fast compression engages. Slow = punchy transients.
100 ms
How fast compression lets go. Affects rhythmic feel.
0 dB
Boost output to compensate for reduced volume.
6 dB
Soft knee = gradual onset. Hard knee (0) = abrupt.
Input Level
-∞ dB
Output Level
-∞ dB
Gain Reduction
0 dB
💡 What's happening: With these settings, any signal above -20 dB gets reduced by a 4:1 ratio. The compressor kicks in after 10 ms (letting some transient through) and releases after 100 ms. This is a classic vocal or bus compression setting — controlled without being squashed.
📌 Quick Presets
Click a preset to load common compression settings and hear the difference.
🎤 Vocal
Smooth, controlled vocals. Fast attack, medium release.
🥁 Punchy Drums
Slow attack lets transients through. Adds punch and weight.
🎵 Bus Glue
Gentle compression that makes a mix feel cohesive.
🚨 Limiter
Extreme ratio. Brickwall limiting for loudness.
🔀 NY Parallel
Heavy squash settings used in parallel compression.
🌱 Gentle Touch
Barely-there compression. Subtle dynamic control.
