Turn audio into structured analysis and annotated visualizations for AI perception. Liner notes for an AI.

Built by humanjava.com — find this and other tools for the agentic age at huje.tools.

Install

pip install sense-music

Quick Start

from sense_music import analyze

result = analyze("song.mp3")
print(result.summary)
result.save("output/")

Full Example

from sense_music import analyze

result = analyze("song.mp3")

# Structured data
print(f"{result.bpm.tempo} BPM, {result.key.key} {result.key.mode}")
print(f"Genre: {result.genre}, Mood: {', '.join(result.mood)}")

# Sections
for s in result.sections:
    print(f"  {s.label}: {s.start:.1f}s — {s.end:.1f}s")

# Lyrics (requires whisper)
for line in result.lyrics:
    print(f"  [{line.start:.1f}s] {line.text}")

# Save everything
result.save("output/")           # spectrogram.png, waveform.png, analysis.json, analysis.html
result.render_page("song.html")  # self-contained HTML report

Skip Lyrics

If you don't have Whisper installed or want faster analysis:

result = analyze("song.mp3", lyrics=False)
