Why analyze a song before you work with it
Almost anything you want to do with a track — remix it, DJ with it, sync it to video, publish it — starts with the same questions: what's the tempo, what key is it in, and how loud is it? Answering them one tool at a time means three uploads and three result screens. A song analyzer answers all of them in one pass, so you can get on with the actual work.
What's in the analysis
One upload gives you the BPM (tempo), the musical key (major/minor across all 24 keys), integrated loudness in LUFS with true peak in dBTP, plus the file's technical info — duration, sample rate, channels, and size. It's the same analysis engines as our dedicated BPM, key, and LUFS tools, run together.
Analyzing Suno & Udio tracks
AI music generators give you a finished track but almost no information about it — no BPM, no key, no loudness reading. One scan here tells you everything you need to remix it, layer it, check it against streaming loudness targets, or hand it to a collaborator with real specs attached.
How to analyze a song
One step: drop the file. Everything happens locally in your browser — your track is never uploaded to a server.
1. Drop your track
MP3, WAV, FLAC, or M4A. The file is decoded and analyzed with the Web Audio API — nothing leaves your device.
2. Get the full picture
BPM, key, LUFS, true peak, and file info — every analysis runs in one pass and lands on one result screen.
3. Act on it
Set your DAW tempo and key, check loudness against streaming targets, or head over to mastering and a lyric video for the same track.
Who a song analyzer helps
Anyone who needs to know what they're working with before they start working.
AI music creators
Get the full spec sheet for a Suno or Udio track in one scan — tempo, key, and loudness — before remixing, layering, or publishing it.
Producers checking references
Pull the BPM, key, and loudness of a reference track in one pass instead of running three separate tools.
Pre-publish checks
One last look before upload: is the loudness on target, is the true peak safe, and is the file what you think it is?
