Audionaut Open-Source Multitrack Audio Editor Launch

Audionaut delivers a lightweight, cross‑platform multitrack editor with AI‑agent integration

Audionaut is a free, open‑source desktop application that lets users cut, arrange, and export multitrack audio without the overhead of a full DAW. It runs natively on Windows, macOS, and Linux, is built with modern C++ on the JUCE framework, and is licensed under GPL‑3 (or later) with an optional commercial license.

Core features are usable out‑of‑the‑box and focus on precise editing

Multitrack timeline – Create regions, drop clips onto per‑track playlists, and export clean mixes.
Precise cutting & cross‑fades – Clip‑level editing with automatic gap removal and fade handling.
Flexible channel support – Works with any number of audio channels; projects are stored in the .audium format.
Headless CLI – audionaut-cli provides JSON‑encoded commands for scripting, CI, and AI agents. Every command returns a single machine‑readable envelope ({"ok": true, "result": …}) and respects standard exit‑code conventions.
AI‑agent editing via MCP – Claude and other agents can drive the editor using the Model Context Protocol (MCP). Edits appear as single undo steps, preserving transparency for the user.
Audio analysis – Optional integration with the Essentia library adds beat tracking, onset detection, and BIC segmentation.
Stem separation – Built‑in support for demucs.cpp enables automatic vocal, drums, bass, and other stem extraction.

Getting started: clone, build, and run

Clone with submodules
```
git clone --recursive https://github.com/kvoltmer/Audionaut.git
```
or run git submodule update --init --recursive after a shallow clone.
Build Essentia (optional) – Required for analysis features.
```
./Audionaut/Builds/build_essentia.sh
```
Python ≤ 3.11, pkg-config, and CMake 3.x are prerequisites.
Compile for your platform
- macOS – Open Audionaut/Builds/MacOSX/Audionaut.xcodeproj in Xcode.
- Windows – Open Audionaut/Builds/VisualStudio2026/Audionaut.sln in Visual Studio 2026.
- Linux – Install the listed development libraries and run:
```
cd Audionaut/Builds/LinuxMakefile/
make CONFIG=Release -j8
```
Run the GUI – Launch the built Audionaut.app (macOS) or the Windows executable. Projects are opened by double‑click or via the command line.

Use the CLI – Example workflow:

audionaut-cli create song.audium --channels 2
audionaut-cli import song.audium take1.wav take2.wav --position 4.5
audionaut-cli analyze song.audium --types sbic,beat_degara
audionaut-cli auto-edit song.audium --track 0 --measures 4
audionaut-cli export song.audium -o mix.wav --sample-rate 48000 --bit-depth 24

Each step returns a JSON envelope that can be checked for "ok": true before proceeding.

AI‑driven editing with Claude (MCP)

Audionaut implements the Model Context Protocol, allowing Claude or any MCP‑compatible agent to issue edits. After installing Node.js 18+:

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

Keep a project open in Audionaut; each agent‑generated edit arrives as a single undo step. macOS users should store projects in ~/Music because the sandbox restricts file access.

Community feedback and roadmap hints

User suggestions – Early commenters asked for menu‑based file import, keyboard shortcuts for splitting, automatic cross‑fades, envelopes, and effects. The author acknowledges these as future enhancements.
Podcast‑specific use case – A user wondered about automated removal of music sections from podcasts. Audionaut’s CLI auto‑edit and analysis features (when Essentia is enabled) could be scripted to detect and cut such segments.
Feature comparison – Questions about latency, DAW‑level capabilities, and label support indicate that Audionaut targets a lightweight niche between simple editors (e.g., Audacity) and full‑blown DAWs.
Packaging requests – Some users requested Flatpak distribution; currently the project provides native builds and source instructions only.

Licensing, contributions, and support

Dual licensing – GPL‑3 (or later) for open‑source use; a commercial license is available for proprietary integration.
Contributing – The repository includes CONTRIBUTING.md and a CLA. Pull requests are welcome.
Sponsorship – The author encourages sponsorship via GitHub Sponsors to sustain development.

Bottom line

Audionaut fills a gap for developers and podcasters who need a scriptable, cross‑platform multitrack editor that can be controlled by AI agents. Its open‑source C++ core, optional Essentia analysis, and built‑in stem separation make it a versatile foundation for both manual and automated audio workflows.
