Blockfish

Blockfish is a free compressor VST, Audio Unit plugin developed by digitalfishphones. Compatible OS(s): Windows 64b, macOS.

Blockfish is a versatile compressor with countless ways to shape the incoming audio. Unlike many other digital compressors, Blockfish has ‘soul’. It likes to bite, but it can be tamed easily once you’ve learned how to use its potential.

You can remove the front plate and make further adjustments on the circuit board. Everything is possible: clean, transparent, loud, punchy, silky, subtle, fat. But still with a unique sonic character.
