Summary

99Sounds is an independent sound design label and repository of free sound effects and plugins, founded in 2014 by Tomislav Zlatić. Its collections cover cinematic effects, drum samples, field recordings, rain, loops, and other audio. The files and plugins are licensed for royalty-free use in personal and commercial music, video, game, podcast, and sound-design projects, without required credit. You may not sell or redistribute downloaded audio, either on its own or as an attachment to your work; the license also bars using it to make noise, white-noise, sleep-sound, or similar apps. Free sound libraries and plugins cost 0.00 USD per free. Instrument plugins are listed in VST, VST3, and AU formats. The maker says its instruments work with VST and AU hosts on 32-bit and 64-bit Windows and macOS, but macOS Catalina is not supported. Drumplayer includes twelve kits and eight slots with mixing and pitch-modulation controls; Upright Piano offers sampled notes across dynamic layers and adjustable sound controls.
