hear-music

Use the hear-music CLI to perceive audio files. Trigger when the user wants to analyze, transcribe, visualize, or inspect music or audio — generating spectrograms, mel/chroma/waveform images, MIDI transcription, JSON note events with onset/tempo/key estimation, ffprobe metadata, or diagnose hear-music install issues. Examples — "what's the BPM of this track", "make a spectrogram of song.mp3", "transcribe this melody to MIDI", "what key is this in", "show me the structure of this audio file".

Inspect and transform audio files with the hear-music CLI. Use when Codex needs to analyze music or audio into spectrograms, waveform/mel/chroma visualizations, MIDI, JSON note events with onset/tempo/key estimation, ffprobe metadata, or diagnose hear-music installation and PATH issues.
