Welcome to the Schaack Audio Technologies website! We are dedicated to providing you the finest audio software since 2007.

Check out our award-winning DVS (Digital Vinyl System) Quad (a.k.a. Quadscratch), which is compatible with any soundcard [PC: ASIO driver required] and supports connection of up to 4 turntables. No Phono Input soundcard and no Phono Preamps are needed! Just connect your turntables to Line Inputs directly.

Quad is downloadable for free and may be tried out without the Vinyls that you get when purchasing Quad.

Also make sure to grab Transient Shaper as Tryout Version. It is a powerful plugin for both Mac (AU/VST) & Windows (VST) that enables shaping of the Attack and Release phases of sounds with 2 knobs only.

Transient Shaper is the perfect companion for all percussion-related audio processing. After trying it out, you may not be able to live without it anymore.
