SoundCraft
Open-source Pro Tools-style DAW in pure Rust — record, edit, mix and bounce, with MIDI, plugins and agents.
SoundCraft is a free, open-source digital audio workstation that re-creates the Avid Pro Tools workflow in pure Rust: an Edit window for arranging and editing, a Mix window with faders, inserts, sends and automation, and the Shuffle, Slip, Spot and Grid edit modes and tools engineers already know. One Rust codebase runs natively on macOS, Windows, Linux and FreeBSD and in a browser via WebAssembly — no subscription, no account, works offline.
The engine covers real work: multitrack editing with playlists and comping, clip gain lines, fades and crossfades in five shapes; a mixer with ten inserts and ten sends per track, busses, aux inputs, VCAs and routing folders; breakpoint automation for volume, pan, mute, sends and every plugin parameter, recorded live in Write, Touch and Latch; instrument tracks with built-in synths, a piano-roll MIDI editor with a velocity lane, Standard MIDI File import/export and audio-to-MIDI; a score editor with MusicXML export; a picture track with H.264, ProRes and Motion JPEG playback; and surround from stereo to 9.1.6 and Ambisonics. Built-in processors include EQs, compressors, de-essers, room and plate reverbs, saturators and synths, and your CLAP, VST3 and Audio Unit plugins load with their editors too. Bounces go to WAV, AIFF or FLAC with dithering and LUFS metering.
Every action is scriptable: the same commands drive the menus, the keyboard, a CLI, a JSON control channel and an MCP server (claude mcp add soundcraft -- soundcraft-cli mcp --demo), and session.inspect lets agents verify their own work. SoundCraft is honest about being pre-alpha — measured at 94% of the incumbent's menu items and roughly 40% of the way to replacing it for real work, with MIDI controller recording, audio device setup and AAF/OMF session interchange still on the alpha checklist. But where Pro Tools needs a subscription, SoundCraft is free, native and yours.
