SoundCraft

Recording, editing and mixing audio; an open-source, modern digital audio workstation (DAW), built in pure Rust.

A complete digital audio workstation that runs natively on macOS, Windows, Linux and FreeBSD, and in the browser. Multitrack editing, a full mixer with plugins, sends and automation, MIDI, recording and bouncing, and every action scriptable from the command line or by an AI agent.

What it does

SoundCraft follows the workflow audio engineers already know: an Edit window for arranging and editing, a Mix window for balancing, edit modes, tools, playlists, memory locations, AudioSuite processing and the rest. If you've spent years in that workflow, your hands should already know where things are.

Mix window. Ten inserts and ten sends per track, busses and aux inputs, master faders, VCAs, routing folders, solo-in-place with implicit solo, and meters with peak hold.	MIDI editor. Instrument tracks with built-in synths, a piano roll with a velocity lane, step input, quantize, transpose, and Standard MIDI File import and export.
Automation and markers. Breakpoint automation for volume, pan, mute, sends and every plugin parameter, written live in Write, Touch and Latch, plus memory locations and a big counter.	Everywhere. Signed builds for macOS (universal), Windows (x64, x86, Arm), Linux (AppImage, deb, rpm, Flatpak), FreeBSD, and a WebAssembly build that runs in the browser.
Video. A picture track with thumbnails and a Video window that follows the playhead, decoding H.264, ProRes and Motion JPEG in pure Rust, with timecode burn-in and sync offset.	Surround and immersive. Main and bus formats from stereo to 9.1.6 and Ambisonics, a surround panner with divergence and height, object/bed routing and a Renderer window with live speaker levels.
Notation. A Score Editor for MIDI tracks, MusicXML export for Sibelius and other notation programs, and printable engraved scores.	Your plugins too. CLAP, VST3 and Audio Units, with their own editors, their state saved in the session, and every instance created off the audio thread.

Feature tour

• Editing: Shuffle, Slip, Spot and Grid modes; Smart, Selector, Grabber, Trim, Pencil, Zoom and Scrubber tools; cut, copy, paste, duplicate, repeat, shift, insert silence, separate (at selection, on grid, at transients), heal, consolidate, strip silence, nudge; fades and crossfades in five shapes, drawn straight from the clip corners; playlists with comping lanes; clip gain lines; edit groups; single-key Commands Focus shortcuts; trackpad scrolling that follows your fingers and pinch-to-zoom around the pointer; undo for everything.
• Mixing: fader and pan with automation, pre/post sends, busses, aux inputs, master faders, VCA masters, routing folders, solo modes, mute and solo groups, phase invert and trim, clip effects, and automatic plugin delay compensation.
• Automation: volume, pan, mute, send and every plugin parameter; Write, Touch, Latch and Trim passes recorded live from the faders; thin, glide, coalesce and convert to clip gain.
• Plugins: 7-band and 1-band EQ, compressor/limiter, expander/gate, de-esser, maximizer, channel strip, room and plate reverbs, mod delay, chorus, flanger, phaser, saturator, lo-fi, rectifier, pitch shifter, time shift, gain, trim, invert, DC removal, signal generator, dither, a subtractive synth, a drum synth and a sampler (plays any WAV, AIFF, FLAC, MP3 or OGG across the keyboard), all original. CLAP plugins load too. Any processor runs offline as AudioSuite, and user presets save per plugin.
• MIDI: instrument and MIDI tracks, a piano-roll MIDI editor with a velocity lane, an event list, a score view, step input, quantize, transpose, real-time properties, Standard MIDI Files, and Audio-to-MIDI from a sung or played melody.
• Recording: punch in on a selection or on the fly, pre/post-roll, loop recording with a playlist per take, input monitoring through the full channel strip, and autosave with recovery.
• Time and tempo: Bars|Beats, Min:Secs, Timecode (every rate, drop-frame included), Feet+Frames and Samples; tempo and meter maps with a tempo editor; linear, parabolic and S-curve tempo ramps; key signatures and detected chords; Beat Detective and Identify Beat; pitch-preserving Elastic warping.
• Audio files: WAV/BWF/RF64, AIFF/AIFC and FLAC in and out; MP3, Ogg Vorbis, AAC, ALAC, CAF and the audio of MP4/MOV movies in. Any sample rate and bit depth.
• Bounce: mix or stems to WAV, AIFF or FLAC at 16/24/32-bit float with dither and normalisation, reporting peak, true peak and integrated loudness (LUFS).
• Fast: a parallel mix engine, copy-on-write undo, and a UI that holds 120 frames per second with seventy-odd tracks playing.

Getting started

Download a build from the releases page, or build from source with Rust 1.95 or later for the desktop/web UI (the core workspace's declared minimum remains Rust 1.90):

git clone https://github.com/storytold/soundcraft
cd soundcraft
cargo run --release -p soundcraft -- --demo     # opens the demo song

Linux needs the ALSA headers (libasound2-dev on Debian/Ubuntu, alsa-lib-devel on Fedora).

The web build:

cd apps/soundcraft-web && trunk serve --release   # then open http://127.0.0.1:8080

Useful shortcuts: Space play/stop, ⌘= Mix/Edit, F1–F4 edit modes, F5–F10 tools, ⌘E separate, ⌘D duplicate, Enter new marker, ⌘⇧N new tracks. Setup › Keyboard Shortcuts lists them all.

Logs

The desktop app writes its log records to standard error and to logs/soundcraft.log in the settings directory, beside ui.json, Autosave/ and Presets/ (Linux ~/.config/soundcraft/logs/, or $XDG_CONFIG_HOME/soundcraft/logs/; macOS ~/Library/Application Support/SoundCraft/logs/; Windows %APPDATA%\SoundCraft\logs\). A start from a desktop menu or the Dock has no terminal, so this file is what to attach to a bug report: the engine's panic report, audio devices that failed to open or broke, plugins that refused their stored state, CLAP plugins' own messages and files that failed to open land there. Each launch moves the previous log to soundcraft.1.log (and that one to soundcraft.2.log), so the log of a run that crashed survives the next start. The file stops growing at 16 MiB. --version writes no file, and runs with SOUNDCRAFT_NO_PREFS log to standard error only.

The realtime audio thread never writes a record itself: the logger keeps the first one it logs (without waiting or allocating), counts the rest, and the UI thread writes them. The logger is apps/soundcraft/src/logging.rs. The web app logs to the browser console instead.

For agents and scripts

Everything you can click is also a command with an id and JSON parameters, and the same commands are reachable from the menus, the keyboard, the command line, a JSON control channel and an MCP server. Programmatic calls never open dialogs, and session.inspect reports exactly what changed, so an agent can check its own work.

# Headless: load the demo, turn the kick down, add an EQ, bounce.
soundcraft-cli run --demo \
  --cmd 'mix.volume={"track":"Kick","db":-6}' \
  --cmd 'mix.insert={"track":"Bass","plugin":"eq_7band"}' \
  --bounce mix.wav

# Drive the running app.
soundcraft --demo --control 7801 &
soundcraft-cli app --port 7801 transport.play
soundcraft-cli app --port 7801 ui.screenshot '{"path":"shot.png"}'

# Give Claude a DAW.
claude mcp add soundcraft -- soundcraft-cli mcp --demo

# Or keep the agent to some folders (reads and writes are separate roots).
soundcraft-cli mcp --automation-read-root DIR --automation-write-root DIR

See docs/control-protocol.md and docs/mcp.md. soundcraft-cli commands lists every command.

Open SoundCraft › Session Audio Health to check loaded audio availability, sample-rate mismatches and clip source bounds across all playlists, including alternate takes. The report offers a refresh button and suggests how to resolve each issue. Scripts can obtain the same JSON report with soundcraft-cli run --demo --cmd 'session.audio_health={}'. This checks loaded media, not files on disk, signal levels, plugins or routing.

How it's built

SoundCraft is a Cargo workspace of small crates with strict layering: nothing below the UI knows about egui, so the interface could be swapped for another one.

The code never panics on bad input: errors are values, and a malformed file or a bad agent call produces a message, never a crash. cargo xtask ci runs formatting, clippy, the tests, the asset and layering checks and the WebAssembly build.

Status and roadmap

SoundCraft is pre-alpha: it covers 94 % of the incumbent's menu items (measured), about 70 % of its features by presence, and is roughly 40 % of the way to replacing it for real work: record, edit, mix and bounce work end to end, but choosing an audio interface and buffer size, recording MIDI from a controller and session interchange (AAF/OMF) are still missing, and those are the alpha checklist. Translations are missing too. The status, the stage and our effort estimates are in ROADMAP.md; the full assessment is in docs/target-app-parity.md, the ranked list of what's missing in docs/gaps.md, and the menu-by-menu comparison in docs/parity-checklist.md. Bug reports and wish lists are very welcome, in the issues or on Discord.

Downloads

Download SoundCraft from GitHub: the latest release has every build listed below, and all releases have earlier versions and their notes. <ver> in the file names is the version number, and SHA256SUMS.txt lists a checksum for every file.

Windows

Installers and executables are code-signed.

If the app doesn't open on Windows: the desktop app initializes only DirectX 12 by default. Letting wgpu also create an OpenGL instance can crash some graphics drivers (AMD's atio6axx.dll) before the window appears, so the app would flash in Task Manager and quit. WGPU_BACKEND overrides the default for troubleshooting (for example dx12 or vulkan). In PowerShell, from the folder containing the executable:

$env:WGPU_BACKEND = "vulkan"
& .\soundcraft.exe
Remove-Item Env:WGPU_BACKEND                     # restore the default for later launches

An explicit gl override can bring the driver crash back on affected systems. The macOS, Linux and web backend defaults are unchanged.

DirectX 12 shaders are compiled with FXC, which is part of Windows, so no dxcompiler.dll or dxil.dll is needed ("Parent device is lost" at start, #185). $env:WGPU_DX12_COMPILER = "dxc" (or "auto") selects wgpu's DXC handling again for troubleshooting.

macOS

Linux

RISC-V (riscv64): soundcraft-<ver>-linux-riscv64.tar.gz, a tarball only (glibc 2.39+, e.g. Ubuntu 24.04).

FreeBSD

Tracks and Groups, Clips, MIDI Editor, Memory Locations, and Undo History use movable panels. Edit and Mix retain separate arrangements; Clips and MIDI Editor belong to Edit. Transport, plug-in, and specialist utility windows retain their existing hosts. Drag a panel header to a target edge or another header. Its context menu offers Float panel, Move to group, and Close panel. Existing panel toggles reopen panels at their saved location; Reset Panel Layout restores the app layout. Floating panels remain inside the current app window.
