Audio — Claude Code MCP server: audio editing and setup
An MCP server for audio work: it measures loudness, checks specs, cleans recordings, applies EQ, cuts files, and converts formats.
claude mcp add audio -- npx -y audioWhat Audio does
Audio gives an agent MCP tools for loading, analyzing, editing, playing, and converting sound. It can measure loudness, spectrum, beats, pitch, chords, and key; check audio against a named specification; remove noise; apply EQ; trim clips; and save a processed file. WebAssembly codecs handle formats without FFmpeg.
The project uses stream-first processing, virtual edits with undo, and paged data for large files. It also includes a CLI for batch work and scripting. The MCP process starts with npx -y audio, with setup commands listed for Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, and other supported clients.
In Claude Code, install it with claude mcp add audio -- npx -y audio. FFmpeg is not required, so its absence does not block the server’s listed audio operations.
What it helps with
- measure loudness and true peak
- prepare a voice recording for a podcast
- trim an audio file and save a new copy
- identify BPM, key, or chords
- apply denoise and EQ to a recording
Example prompts for the agent
- Make
~/Desktop/interview.m4apodcast-ready and report its loudness before and after processing. - Check
voice.wavagainst podcast requirements, clean it, and save the result asclean.mp3. - Trim
song.mp3, normalize its level, and describe what changed.
