What it is
99Sounds is an independent sound design label and repository of free sound effects and plugins, launched in 2014 by Tomislav Zlatić. Its collections include cinematic effects, drum samples, field recordings, rain sounds, loops, and other audio. Files and plugins are licensed for royalty-free use in personal and commercial creative projects, including music, video, games, podcasts, and sound design; attribution is not required.
The license does not permit selling or redistributing downloaded audio, whether on its own or as an attachment to another work. It also bars use of the sounds in noise, white-noise, sleep-sound, or similar apps. Free instrument plugins are listed in VST, VST3, and AU formats. The maker says its virtual instruments work with VST and AU hosts on 32-bit and 64-bit Windows and macOS, but not macOS Catalina. Drumplayer includes twelve drum kits, eight slots, output and channel controls, and a pitch-modulation LFO. Upright Piano offers sampled notes across dynamic layers and adjustable sound controls. Sample formats include WAV, MIDI, NKI, SFZ, and Serum presets.
