Audionaut - Open-source multitrack audio editor with AI agent control
Show HN: Audionaut – an open-source cross-platform multitrack audio editor
Audionaut is a free, open-source multitrack audio editor and recorder built in modern C++ with JUCE, running natively on Windows, macOS, and Linux. It offers precise cutting, per-track playlists, multi-channel support, and clean exports without the complexity of a full DAW. What sets it apart is MCP support: Claude and other AI agents can drive edits directly, turning commands into single undo steps. It also includes stem separation via demucs.cpp, audio analysis with Essentia, and a headless CLI for scripting and CI. Perfect for music, podcasts, and multitrack projects.
Audionaut speaks MCP, so Claude and other agents can edit your sessions.

Hi, i finally feel confident enough to announce Audionaut. It's been 3-4 years in the making and my initial motivation was to edit my own multi-channel recordings with the old Sound Designer II workflow (create regions, drop to a playlist, export playlist, done). It got a little bigger now and the most current feature is the agent editing, which is imho very useful since you have the UI which always provides transparency.
To try the agent part with Claude Code (app and Node 18+ installed):
claude mcp add audionaut -- npx -y audionaut-mcp
Edits land in the open project as one undo step each, and saving stays with you. On macOS the app is sandboxed, so keep projects in ~/Music.

Congrats on the launch.
Some feedback after using it for a few minutes; It's a good effort and the software is useable. I understand there is a lot more to come. it would be nice to have:
- ability to import files into tracks from a menu or context menu
- keyboard short cut keys for for splitting, etc.
- automatic crossfade when moving clips into each other
- envelopes
- effects
- I think Sony Vegas had one of the most intuitive audio editing experiences when working with tracks and clips, maybe adopt what worked from it.

Wow, thanks! I don't have time to look at it now, but it'll go high on my list. I had a quick look though the docs and I see it supports regions. Does it have labels too? Can I import/export labels and/or regions from file?
Perhaps an idea to create a docs/features.md to mention what it can do. Might even help LLMs picking up your project. Thanks again, I'm very exited!

This is a pretty neat looking platform, especially the production pipeline possibilities in it. This possibly should be front and center a bit more. Adding to my stack to try out.

Task I want but have been too lazy - I have a favorite podcast, that I often fall asleep to. Certain parts with music etc. wake me up. I'd like to chop those parts out as automatically as possible. Can I do that here by e.g. giving some example edits to a few files, and asking to remove similar stuff from other files?
