PsyPress
Four compressors in one, with a curve you can watch work.
Choose how it responds, from exact and transparent to slow and thick, and choose what it listens to, from instant peaks to perceived loudness. The transfer curve shows where your signal sits on it as it plays, and the meters show what went in, what came off and what came out.
Two switches decide the sound.
Precise · Opto · FET · Vari-Mu
Four responses modeled on the classic families of hardware compressor. Precise does exactly what the controls say. The others bring the timing and character of the circuits they are named after.
Peak · Analytic · RMS · Loudness
What the compressor reacts to: the instantaneous peak, a smoothed analytic envelope, the average power, or loudness weighted the way you hear it.

Pre-release installers are not yet code-signed with a Windows certificate, so SmartScreen may say it “prevented an unrecognized app from starting”. Choose More info, then Run anyway. Release builds will be signed.
In PowerShell, Get-FileHash .\PsyPress-1.0.0-beta-20261008-1643.exe should print the SHA-256 above. The signature file carries the same hash, signed with the MadPsy key that signs every plug-in’s content.
Bugs, crashes and ideas all help: say which host you use and what you were doing. Contact us, or join the feedback list and we will ask now and then.
