Song Analyzer
Upload your track, pick your genre, and get an honest diagnosis: what was measured, what it is compared against, and what to do about it.
MP3, WAV, M4A, FLAC · up to 100 MB
Sets the references to what your style actually releases.
Why this tool exists
When an independent artist releases a song and nothing happens, they almost never find out why. They send it to a friend, the friend says it is good so as not to crush them, and that is where the information ends. Without knowing what went wrong, only three explanations remain: bad luck, no money, or no talent. None of them tells you what to do tomorrow.
Very often the problem is not the song: it is that the master distorts once converted to MP3, that the low end vanishes on a bar speaker, that the track takes thirty seconds to get going, or that the beat came from a compressed MP3. None of that has anything to do with talent, and all of it can be measured.
What it analyses
Loudness and master: integrated loudness in LUFS, true peak in dBTP, digital clipping and crest factor. Finds out whether your track will distort on Spotify and whether the limiter has squashed it.
Clarity and tone: band balance, low-mid excess, missing air and real bandwidth. Detects the "inside a can" sound and whether an MP3 slipped into your chain instead of the original file.
Stereo: phase correlation and mono compatibility. Detects whether your bass cancels on a bluetooth speaker or in a club.
Structure and attention: how long your song takes to get going, silence at the start and end, duration, and long stretches without change.
Tuning: deviation in cents from concert pitch and how tightly the notes land.
Technical hygiene: sample rate, DC offset, mains hum and noise floor.
What it does NOT do, and why that matters
It does not tell you whether your song is good. It cannot, and neither can anyone else: that is not measurable. If a tool puts a score on the artistic quality of your track, it is handing you an opinion dressed as science — exactly what your friend does when they say it is good.
The score here is technical: the percentage of verifiable checks your file passes. Every finding carries the measured value, the reference it is compared against, and what to do. If something cannot have all three parts, it does not appear in the report.
Genre changes the diagnosis
A trap track at -8 LUFS is normal; a ballad at -8 LUFS is crushed. A twelve-second intro is suicide in reggaeton and perfectly reasonable in R&B. That is why you pick the genre first: references adjust to what your style actually releases, not to a studio ideal nobody meets.
Frequently asked questions
Is my song uploaded anywhere?
No. All analysis happens inside your browser and the file never leaves your device.
Will it tell me if my song will succeed?
No, and be wary of anyone who promises that. It tells you what technical problems your file has and how to fix them, which is the only thing that can truly be known.
What is a LUFS?
It is the unit platforms use to measure perceived loudness. Spotify, YouTube and Amazon normalise everything to -14 LUFS, so pushing your master past a certain point does not make you louder: it only makes you flatter.
Can I analyse just the vocal?
Yes, and for tuning it is far more precise. Upload the vocal track on its own and the tuning analysis will tell you exactly what is going on.
Is it for demos or masters?
Both. On a demo it flags recording problems; on a master, mixing and limiting problems.
