Audionaut is a free, open-source multitrack audio editor and recording application designed for macOS, Windows, and Linux. Developed using the JUCE framework in C++, the application provides precise cutting, multi-channel support, and per-track playlists without the complexity of a full digital audio workstation (DAW).
Audionaut: Open-Source Multitrack Audio Editor with MCP Support for AI Agents
A key feature of Audionaut is its support for the Model Context Protocol (MCP), which allows AI agents such as Claude to drive audio editing sessions. By installing the audionaut-mcp package via Node.js, users can enable agents to perform edits that appear as undo steps within the application.
The software includes several advanced audio processing capabilities. It utilizes a C++ port of Meta's Demucs for stem separation and integrates the Essentia library for audio analysis, such as beat tracking and onset detection. For headless operation, audionaut-cli provides a command-line interface that enables AI agents to execute workflows—including creating, analyzing, and exporting projects—via JSON-formatted machine-readable output.
