ay compressor
Musical compressor with program-dependent release.

what it's about
AyCompressor automatically blends a fast and a slow release depending on the character of the signal — transients stay lively, dense passages breathe calmly. The sidechain high-pass keeps bass energy from making the whole mix pump. Transfer curve and GR history show you live what's happening.
in detail
- Program-dependent release via crest-factor analysis
- Sidechain high-pass against bass pumping
- Live transfer curve with threshold marker + GR history
- Auto makeup on demand, mix control for parallel compression
- 19 factory presets for vocals, drums, bus and master
