Sounds of Revolution (SOR) is a German sound design company founded and run by Oliver Schmitt, specializing in royalty-free sample libraries and synthesizer presets aimed primarily at producers of techno, minimal, tech house, and other electronic dance music. The brand has built a catalog spanning hundreds of sample packs and patch banks, including titles such as the SOR Ultimate Bundle, Club Revolution, Minimal Techno Revolution, and the Clicks & Glitches series, with content delivered as 24-bit WAV loops, one-shots, and presets compatible with major DAWs like Ableton Live, FL Studio, Logic Pro, Cubase, and Bitwig.

Beyond its own releases, SOR has produced sound content and factory libraries in collaboration with companies including Steinberg, Arturia, reFX, Xfer Records, Twisted Tools, Yum Audio, and D16 Group — most notably contributing sound design to the D16 PunchBOX kick drum synthesizer. In 2011, Schmitt co-founded the sound label and distribution platform Resonance Sound together with Martin Breuhahn of CFA-Sound, which serves as the primary outlet for SOR releases alongside third-party retailers like Loopmasters and Black Octopus Sound.
