kvoltmer/Audionaut: Audionaut skilled audio enhancing and audio recording · GitHub

A free, open-source multitrack audio editor that AI brokers can drive over MCP.

audionaut.app · Discussions · Sponsor

Audionaut is a free, open-source desktop utility for easy audio enhancing and recording. Whether you are engaged on music, podcasts, or multitrack recordings, it provides you exact chopping, per-track playlists, versatile multi-channel help, and clear exports — with out the burden and complexity of a full DAW. Audionaut is written in trendy C++ on the JUCE framework and runs natively on Windows, macOS, and Linux.

Audionaut speaks MCP, so Claude and different brokers can edit your classes. With the app and Node.js 18+ put in:

claude mcp add audionaut -- npx -y audionaut-mcp

Keep the challenge open in Audionaut and every edit arrives as one undo step. On macOS, hold tasks in your Music folder. Claude Desktop setup and particulars: manual, chapter 11.

Make certain to clone with submodules:

git clone --recursive https://github.com/kvoltmer/Audionaut.git

or as soon as cloned do:

git submodule replace --init --recursive

The evaluation options (BIC segmentation, onset detection, beat monitoring) hyperlink in opposition to a static construct of the Essentia submodule. Build it as soon as after testing the submodules:

./Audionaut/Builds/build_essentia.sh

The script builds Essentia’s Third-party dependencies statically (sluggish, skipped on re-runs; pressure with FORCE_3RDPARTY=1), then configures and builds Essentia itself with its waf construct system into Submodules/essentia/construct. It patches Essentia’s Linux-oriented Third-party construct scripts within the working tree as wanted for macOS/Apple Silicon, so the essentia submodule will present as soiled afterwards — do not commit these adjustments.

Prerequisites:

• Python ≤ 3.11 — Essentia’s bundled waf wants distutils, eliminated in Python 3.12. The script picks an acceptable interpreter mechanically; override with PYTHON=... ./Audionaut/Builds/build_essentia.sh.
• pkg-config (e.g. brew set up pkg-config)
• CMake 3.x advisable — some Third-party deps ship very previous CMakeLists that CMake 4.x refuses (e.g. pip set up "cmake~=3.31.0").

Building Essentia is elective: with out it, ESSENTIA_ENABLED auto-detects off and the app and exams compile with the evaluation options disabled.

Stem separation runs demucs.cpp, a C++ port of Meta’s Demucs, compiled straight from the Submodules/demucs.cpp submodule — no separate construct step. It wants the submodule’s vendored Eigen (Submodules/demucs.cpp/vendor/eigen, a nested submodule that --recursive fetches); the CMake construct detects it and units AUDIONAUT_ENABLE_DEMUCS accordingly. The mannequin weights will not be within the repository: the app downloads them on first use into its Models folder, or level the CLI at a duplicate with --model.

Visual Studio 2026 — open the Visual Studio resolution situated right here:

Audionaut/Builds/VisualStudio2026/Audionaut.sln

Linux Makefile — set up dependencies:

sudo apt set up libasound2-dev libjack-jackd2-dev ladspa-sdk libcurl4-openssl-dev libfreetype-dev libfontconfig1-dev libx11-dev libxcomposite-dev libxcursor-dev libxext-dev libxinerama-dev libxrandr-dev libxrender-dev libwebkit2gtk-4.1-dev libglu1-mesa-dev mesa-common-dev libxi-dev libegl-dev

then compile:

cd Audionaut/Builds/LinuxMakefile/
make CONFIG=Release -j8

See the Catch2 tests README.

audionaut-cli provides scripts, CI and AI brokers headless entry to .audium
tasks — no GUI, no audio machine. It builds alongside the exams:

cmake -B construct -S Audionaut/Catch2Tests
cmake --build construct -j8 --target AudionautCli
./construct/AudionautCli_artefacts/AudionautCli --help

Every command takes --json to emit precisely one machine-readable outcome
envelope on stdout ({"ok": true, "outcome": ...} or {"ok": false, "error": ...}) with all logging on stderr, plus --quiet. Exit codes: 0 success,
1 operation failed, 2 utilization error, 3 function unavailable on this construct
(e.g. analyze with out Essentia). Option values could also be given as --opt worth
or --opt=worth.

A typical agent circulate: create → import → analyze → auto-edit/assemble
→ export, checking ok in every --json envelope. Projects written by the
CLI open within the GUI app and vice versa.

End-user documentation lives within the User Manual.

CLI invocations report nameless utilization statistics underneath the identical strictly
opt-in consent because the app (one cli_command occasion: verb and exit code) —
nothing is shipped until consent was granted within the app’s settings. Set
AUDIONAUT_DISABLE_ANALYTICS=1 to change the CLI’s reporting off regardless
(CI environments, scripts).

The major Audionaut app additionally accepts the identical verbs (Projucer-style): run
the app binary with a verb and it executes headlessly and quits with the
command’s exit code, even whereas a GUI occasion is open — a file argument or
no arguments launches the GUI as standard.

./Audionaut.app/Contents/MacOS/Audionaut export ~/Music/tune.audium -o ~/Music/combine.wav

Note: the macOS app is sandboxed, so its in-app CLI can solely attain
entitlement-covered areas resembling ~/Music; the standalone
audionaut-cli construct has no such restriction. On Windows, the app is a GUI
program — the shell immediate returns instantly and output interleaves with
it; desire audionaut-cli for scripting there.
