audionaut.app · Discussions · Sponsor

Audionaut is a free, open-source desktop application for effortless audio editing and recording. Whether you're working on music, podcasts, or multitrack recordings, it gives you precise cutting, per-track playlists, flexible multi-channel support, and clean exports — without the weight and complexity of a full DAW. Audionaut is written in modern C++ on the JUCE framework and runs natively on Windows, macOS, and Linux.

Use with Claude

Audionaut speaks MCP, so Claude and other agents can edit your sessions. With the app and Node.js 18+ installed:

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

Keep the project open in Audionaut and each edit arrives as one undo step. On macOS, keep projects in your Music folder. Claude Desktop setup and details: manual, chapter 11.

Checkout

Make sure to clone with submodules:

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

or once cloned do:

git submodule update --init --recursive

Essentia (audio analysis)

The analysis features (BIC segmentation, onset detection, beat tracking) link against a static build of the Essentia submodule. Build it once after checking out the submodules:

./Audionaut/Builds/build_essentia.sh

The script builds Essentia's 3rd-party dependencies statically (slow, skipped on re-runs; force with FORCE_3RDPARTY=1), then configures and builds Essentia itself with its waf build system into Submodules/essentia/build. It patches Essentia's Linux-oriented 3rd-party build scripts in the working tree as needed for macOS/Apple Silicon, so the essentia submodule will show as dirty afterwards — don't commit those changes.

Prerequisites:

• Python ≤ 3.11 — Essentia's bundled waf needs distutils, removed in Python 3.12. The script picks a suitable interpreter automatically; override with PYTHON=... ./Audionaut/Builds/build_essentia.sh.
• pkg-config (e.g. brew install pkg-config)
• CMake 3.x recommended — some 3rd-party deps ship very old CMakeLists that CMake 4.x refuses (e.g. pip install "cmake~=3.31.0").

Building Essentia is optional: without it, ESSENTIA_ENABLED auto-detects off and the app and tests compile with the analysis features disabled.
