AI Song Analyzer: Get Key, BPM, Mood and Feedback on Any Song
Wondering what key your song is in, how fast it really is, or why the chorus feels flat? Upload a track and this AI music analyzer tells you. aisong.lol reads the key, BPM, genre, mood, and song structure, then adds plain-English mix feedback so you know what to fix next. Works on your own demos, beats, and finished songs.
AI song analyzer: what it tells you, fast
Short version: a song goes in, a report comes out. An AI song analyzer does the listening homework for you, so you get the facts about a track without tapping along to a metronome or guessing at chords.
- What: A report on key, BPM, genre, mood, structure, and mix.
- Who: Producers, songwriters, DJs, and curious listeners.
- Input: An audio file you upload, like MP3 or WAV.
- Free: 3 generations with a free account.
How it works: upload, analyze, read the report
Three steps. No music theory degree needed.
1. Upload a song
Drop in a demo, a beat, a mix, or a finished master. Use audio you own or have the right to work with. Upload a common audio file like MP3 or WAV; the uploader shows size and length limits.
2. Let the AI listen
aisong.lol scans the track for tempo, tonal center, energy, sections, and balance. Most songs finish after a short wait.
3. Read and act on the report
You get the numbers plus notes in plain words. Copy the notes you need from the report.
What is in the report
Every report covers the same core facts, so you can compare songs side by side.
- Key and scale: the tonal center and whether it reads major or minor.
- BPM: the tempo, plus a note if it might be half-time or double-time.
- Genre: the closest style matches for the track.
- Mood: the feel, like bright, moody, tense, or chill.
- Structure: where the intro, verses, choruses, and bridge land.
- Mix feedback: notes on balance, loudness, and clarity.
Music analysis AI for mix feedback
Numbers are handy. Feedback is where music analysis AI earns its spot in your workflow. Instead of a wall of meters, you get notes like "the low end is crowding the kick" or "the vocal sits behind the guitars in the chorus."
Treat it like a sharp friend with good ears: useful for a second opinion, not the final word. Your taste still wins.
- Balance: is anything buried or poking out?
- Low end: is the bass and kick muddy or clean?
- Loudness: is it close to streaming levels?
- Space: does the reverb wash things out?
Who uses AI music analysis
Different people, same question: what is going on in this track?
Producers
Check key and BPM before you sample, remix, or stack a new part. Then get a quick read on your mix before you send it out.
Songwriters
See your song's structure at a glance. Is the chorus arriving too late? Is the bridge earning its place?
DJs and playlist makers
Group tracks by key, tempo, and mood so sets and playlists flow.
Tips for a more useful analysis
A few habits get you better results:
- Upload the full song, not a clip, so structure reads correctly.
- Use a clean bounce. Heavy compression from a phone recording can skew the mix notes.
- Compare against a reference track in the same genre.
- Run it again after changes to see if the fix landed.
- Double check key on songs with key changes or lots of borrowed chords.
How accurate is it?
Honest answer: tempo and key are usually solid on clear, steady songs. Tracks with tempo drift, key changes, or very sparse arrangements are harder. Genre and mood are educated reads, not facts. Treat key, BPM, and genre reads as a strong first guess, then trust your ears. Use the report as a strong starting point, then trust your ears.
Analyzer vs transcription vs pitch and BPM tools
These sound alike but do different jobs. The analyzer describes a song: key, tempo, mood, structure, and how the mix sounds. Transcription writes out every note as MIDI or sheet music. The pitch, BPM, and key tools change audio, like shifting pitch or speeding up a track. If you want answers and feedback, not new audio or a score, you are in the right place.
Free, files, and privacy
You can try it free online. Free covers 3 generations with a free account. Pro is $10/mo for 100 songs and Premier is $30/mo for 400 songs.
See the privacy policy for how uploads are stored. Analyzing a song does not change who owns it.

Who this is not for
This is not a mixing engineer and it will not fix your track for you. It does not write sheet music, change pitch or tempo, or make new music. It cannot tell you if a song will be a hit, and it is not a copyright or sample clearance check. If you need a detailed, human review of a release, hire an engineer or a producer you trust.
