99Sounds vs TONSTURM

99Sounds is an independent sound design label and free sound effects repository launched in 2014 by Tomislav Zlatić. Its collections include cinematic effects, drum samples, field recordings, rain sounds, loops, and other categories. Audio files and plugins are royalty-free for personal and commercial projects, including music, video, game development, podcasts, and sound design, and attribution is not required. The license does not permit selling or redistributing downloaded audio, either separately or as an attachment to 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 instruments work with VST and AU hosts on 32-bit and 64-bit Windows and macOS, but not macOS Catalina. Drumplayer includes twelve kits, eight slots, stereo and multiple mono outputs, channel volume and pan, and pitch-modulation LFO. Upright Piano includes four sampled notes per octave, six dynamic layers per note, and adjustable envelope, tremolo, filter, and reverb. Sound and plugin downloads cost nothing.

TONSTURM sells royalty-free sound-effect libraries, ambience collections, software plugins, and virtual instruments for sound designers and composers. Its products target professionals in film, games, and multimedia, including post-production teams and game developers. The catalog lists 14,000 professionally recorded and mastered sounds in WAV format, with commercial and broadcast use supported. Ambience libraries include surround, 5.0, and 7.0.2 formats for Dolby Atmos workflows. Software tools support sound editing, processing, and mixing. SpinTracer provides real-time motion control, a spatial motion engine, up to 16 sound objects and input channels, tremolo, floor reflections, and binaural panning. DopplerPRO controls Doppler timing, speed, peak position, path shape, and floor reflections, and supports VST, VST3, AAX, Audio Suite, and Audio Units. It requires internet for activation but works offline afterward, with machine or USB-dongle iLok licensing. Complete Software bundles eight instruments and plugins. Mac and Windows installers are listed, and TONSTURM operates from Cologne, Germany.
