Free Music Analysis Tools
One upload, every answer: your strongest seconds, exact BPM and key, LUFS vs platform targets, and a 0–100 Virality Score. Each tool below is a different lens on the same free analysis — running in about 60 seconds.
Hook Finder
Upload your song, get the exact seconds where it hits hardest — with timestamps and the reason why. The moment you should clip for TikTok.
BPM & Key Finder
Exact tempo and musical key of any track, measured from the audio — not guessed from metadata. Plus loudness and energy profile.
LUFS Checker
Integrated LUFS and true peak of your master, checked against Spotify, YouTube and Apple Music targets — with the exact dB delta.
Virality Score Checker
A 0–100 score for your song's viral potential — hooks, energy, production, lyrics — benchmarked against real releases.
Which tool answers which question?
Most musicians arrive with one concrete question. Here is where each one gets answered — and because all four tools read from the same analysis, you get the other three answers with it.
Hook Finder → — Your ranked best moments with start and peak timestamps — open the clip on the strongest second instead of the intro.
BPM & Key Finder → — Beat-tracked tempo and the musical key with mode (e.g. A minor), measured from the waveform — works on unreleased and AI-generated tracks.
LUFS Checker → — Integrated LUFS and true peak vs the -14 LUFS Spotify target (and YouTube / Apple Music) — with the exact dB the platform will turn you down.
Virality Score Checker → — A 0–100 score with a per-dimension breakdown: whether hooks, energy, production or lyrics carry the track — and what drags it.
Why one upload powers four tools
A separate BPM finder, a separate loudness meter and a separate “rate my song” site each make you upload again — and none of them see the whole picture. Songbrain runs one full analysis over your audio: tempo and key, loudness and true peak, energy structure, vocals and lyrics, hooks and their exact positions. The tools on this page are simply the four most-asked questions, answered from that one result.
The same analysis also classifies your genre and subgenre, scores your lyrics, renders 7 beat-synced reels cut around your best moments and lays out a 2-week posting plan — so the numbers come with something to post.
Common questions
Yes. The analysis behind them is free and takes about 60 seconds — no card required. Each tool page describes one part of the same result: hooks and timestamps, BPM and key, LUFS vs platform targets, and the 0–100 Virality Score.
No — that's the point. One upload runs one full analysis, and every tool on this page reads from it: the hook timestamps, the BPM and key, the loudness check and the Virality Score all sit in the same result, next to genre classification, lyrics scoring and 7 ready-to-post reels.
MP3 or WAV, full track, 30 seconds minimum. Unreleased demos, raw bounces and AI-generated songs (Suno, Udio) work exactly like released tracks — everything is measured from the audio itself, not from metadata.
Single-purpose meters give you one number and stop. Here the same upload answers the follow-up questions too: not just 'my song is 142 BPM' but which seconds to clip, whether the master survives normalization, and whether the track is worth pushing — with a breakdown of why.
Your song is analyzed and you get the results — the audio is not published anywhere. You decide afterwards whether to create an account to keep the analysis and download the generated reels.
Or just run the full analysis
Every tool result above comes from one analysis — plus genre classification, lyrics scoring, 7 ready-to-post reels and a 2-week posting plan. Free, no card.
