Collapse
Two ways to collapse.
Classic compression. Violent alternatives.
Features
Two compression algorithms
Classic for transparent control, Fracture for character you can't find anywhere else.
Post-compression saturation
Tanh soft-clip at 2× oversampling adds harmonic warmth without aliasing artifacts.
Stereo width control
M/S processing at the end of the chain, from full mono to wide expansion.
Sidechain HPF
Keep bass frequencies out of the detector so low end doesn't drive the whole mix.
A/B comparison + full undo history
Flip between two parameter states instantly, or step back through every move you've made.
About Collapse
Most compressors work the same way. Measure the signal, compare it to a threshold, apply gain reduction. The math is tidy, the results are predictable, and a well-set compressor in Classic mode is exactly that — feed-forward, smooth, the kind of transparent gain riding that disappears into a session and does its job.
Fracture is a different story. It runs a proprietary dynamics engine under the hood that reacts to transients in a way a conventional compressor simply doesn't. Push it and it doesn't just turn things down — it does something to the signal that's easier to hear than explain. Drums come apart differently. Peaks don't get rounded off, they get taken apart. It's aggressive in a way that ratio and attack time alone can't account for.
Both modes share the same signal chain: sidechain high-pass filter, post-compression saturation at 2× oversampling, M/S width control, and independent input and output trim with metering at each stage. A/B slots let you compare two parameter states in real time. A full undo history means nothing is ever permanent. Classic or Fracture — two ways to collapse.
Spec sheet
Controls
| Control | Range | Description |
|---|---|---|
| THRESH | −60 to 0 dB | The level above which the compressor begins acting. |
| RATIO | 1:1 to 20:1 | How aggressively signal above the threshold is reduced. |
| ATTACK | 0.1 to 200 ms | How quickly the compressor responds once the threshold is crossed. |
| RELEASE | 5 to 2000 ms | How quickly the compressor stops acting once signal falls back below threshold. |
| KNEE | 0 to 24 dB | Controls the softness of the transition into compression around the threshold. |
| MAKEUP | 0 to +24 dB | Output gain applied after the compressor to restore level. |
| MIX | 0 to 100% | Blends compressed signal with the dry input for parallel compression. |
| WIDTH | 0 to 200% | Mid/side stereo width control applied after compression and saturation. |
| SC HPF | 20 to 500 Hz | High-pass filters the sidechain detector so bass doesn't drive gain reduction. |
| DRIVE | 1× to 20× | Bends the tanh saturation curve from nearly linear to aggressively clipped. |
