A25 has been modeled after a beautiful stereo compressor, with a few "modern" add-ons: sample aligned dry-wet control. Mid-side balance control of action of the compressor (sets where the processing is done between mid and side components of the stereo field). True auto-gain, for easy level-matched comparison. Through-clipboard preset management system (copy and paste between instances).
Attackease takes an audio input (I.e. A drum mic track) and separates the incoming audio into two tracks, attack and sustain, with selectable parameters.
