OpenStudio
What OpenStudio is
OpenStudio is a free, open-source desktop digital audio workstation for recording, editing, mixing, and generating audio. It runs on Windows, macOS, and Linux; listed minimum systems are Windows 10+, macOS 12+, and Ubuntu 22.04+. For audio and MIDI work, it offers multitrack recording, timeline editing, MIDI input, a piano roll, quantize, and audio-to-MIDI conversion. Its mixer provides routing and automation, and it can render master mixes or stems in WAV, AIFF, FLAC, MP3, and OGG, as well as export DDP. Plugin support includes VST3, CLAP, and LV2, with optional ARA2 hosting. The built-in NAM Rack works with local capture files and can browse TONE3000 packs; an account is optional for that catalog. Optional AI tools can separate audio into six stems or generate, vary, and continue audio locally after setup. They are separate from the base installer, and the managed runtime currently targets Apple silicon rather than Intel Macs. The maker says project files, audio, presets, and exports stay on the user’s device, and its standard local AI workflow does not upload audio to external servers.
Who it suits
OpenStudio suits musicians and audio creators who want desktop recording, editing, mixing, MIDI sequencing, and plugin hosting without a paid plan or account. Its optional local AI tools may also suit users interested in stem separation or audio generation, provided their system fits the managed runtime’s current Apple silicon target.
