Scope and limits：The report is a quantitative aid, not a rights or exam verdict. Analysis does not change licensing.
Search and usage guide
Full-dimension analysis is for understanding a track before you edit: upload a song or demo and get BPM, key, chords, form, plus a 23-chapter report on structure, harmony, stems, loudness, melody, and AI constraints. It does not print sheet music or export DAW MIDI—use Audio to Score or Audio to MIDI for those.
Best for remix prep, teaching structure, archiving demo loudness/key, feeding Aurols AI constraints, and planning short-video cues. Not for ready practice PDFs (/free-score) or trimming a ringtone (audio editor).
Typical order: analyze first, then separate, score, or convert MIDI. Platform AI works can be sent here directly. Optional lyrics improve rhyme and form. The report is a quantitative reference; rights clearance and exam certificates are handled separately.
Run music analysis on this page, /en/music/analysis-report, then read the report in My Works. Upload only audio you may analyze.
FAQ
What is in a full-dimension music analysis report?
This page outputs 23 quantitative chapters: AI creation constraints (engineering prompts, BPM / mode / chorus window), rhythm (meter, beat grid, groove), form (8 sections, chorus anchors, DAW cues), key and harmony (key candidates, Roman-numeral progressions, modulation hints), melody transcription, mastering loudness (LUFS / LRA), spectrum, lyric emotion, EBU R128 QC, and Demucs-class 6-stem references. Default downloads are analysis text and a full PDF; some tiers add a composition skeleton, a chord-progression document, and MusicXML. Platform AI tracks can be sent here directly.
Which audio formats can I upload?
mp3, wav, flac, and m4a upload via object storage. You can also pick a synced platform AI track with lyrics auto-filled. Heavily damaged or ultra-low-bitrate files may weaken some metrics. Lyrics are optional: paste matching lyrics to unlock rhyme and emotion chapters; acoustic and form analysis still run without them. Quotas follow the submit page.
How does this relate to MIDI or sheet tools?
Analysis is for reading a track: BPM, key, form, loudness, and creation constraints. It does not print charts or export standard DAW MIDI. Use Audio to Score for notation (reference / sing-along / band packs) and Audio to MIDI for editable notes. Typical order: analyze first, then separate, score, or convert MIDI.
Is the report a rights or exam certificate?
No. It is a quantitative aid for BPM, key, form, and loudness—useful for remix, teaching, and follow-up creation. It does not change licensing and cannot replace registration, a license, or an exam score. Upload only audio you may analyze.
