Audio File MCP App

counterpoint-studio/audio-file-mcp-app

Turns local audio files into an interactive waveform UI inside your MCP host, with playback, EBU R128 loudness metrics (LUFS, LRA, true peak), and a reassigned spectrogram colored by spectral centroid. You call display_audio_file with an absolute path and get transport controls, looping region selection, and both global and instantaneous loudness stats. The playhead position and any selected region are exposed back to the model so follow-up prompts can reference what you're actually hearing. Runs over stdio via npx, works in Claude Desktop, VS Code, Goose, and the MCP Inspector. Reach for it when you need to analyze audio characteristics or discuss specific moments in a file without bouncing between a DAW and your chat window.

Readme

Audio File MCP App

An MCP App for playing and inspecting local audio files in an MCP host.

Audio File MCP App running in Claude Desktop

Renders an in-conversation UI with playback, metadata, loudness, a spectrogram, and an optional annotation-lane timeline.

File metadata, loudness statistics, the current playhead position, any selected region, and the annotation lanes active at the playhead are also exposed back to the model, so follow-up tasks can refer to what the user is actually hearing and looking at.
