Point Claude at any audio file and it can tell you the key, tempo, dynamics, timbre, percussive character, stereo field, structural sections, and how the music evolves over time -- all from raw audio analysis, no images, no guessing, under 1% context window usage. Compare two tracks side-by-side. Detect where the music changes structurally — intro, verse, chorus, bridge — and zoom into the moments that matter. What is this? LLMs can see (vision) and read (text), but they can't hear. This project bridges that gap by running real audio analysis -- the same DSP techniques used in music information retrieval research -- and returning structured numerical data that Claude can reason about. It's an MCP server that exposes audio analysis as tools Claude can call on demand. Ask Claude to analyze a song and it will decode the audio, run spectral/harmonic/rhythm/percussive analysis, and return the results as compact text. No spectrograms, no images, no wasted tokens. Full analysis of a 60-second track completes in under 2 seconds (including source separation). Pure Rust. No Python, no FFmpeg, no system dependencies. Features - Audio decoding -- mp3, wav, flac, ogg, aac via Symphonia (pure Rust) - Spectral analysis -- centroid (brightness), bandwidth (richness), rolloff, flatness (tonality) - Frequency band energy -- RMS energy across 7 standard producer bands (sub-bass through brilliance) for mix diagnosis -","default_branch":null,"files":null,"tree":[],"storefront":"/r/JuzzyDee","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/JuzzyDee/audio-analyzer-rs/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
