Your track is finished.
Is it ready to send?
Upload the bounce and the Demo Analyzer measures it the way a label will hear it: loudness against your own genre, true peak, dynamics, the stereo image and the low end. Then it says what to fix, and which of 1,300+ labels it fits.
The audio is deleted once the analysis finishes. Only the reading is kept, and only for 20 days.
Six readings, measured off your audio
Not estimated from a model. The file is decoded and measured to the broadcast standard, ITU-R BS.1770, the same way a mastering engineer’s meter does it.
Against the median of your own genre, not a streaming number.
The wave between the samples, reconstructed at 16 times the rate.
Loudness range to EBU Tech 3342: the distance between the loud parts and the quiet ones.
How wide the image is, and whether the sides survive a mono sum.
Phase between the channels. Below zero, a club rig eats the track.
Whether the bass is mono where it has to be.
How loud is your genre, actually
−14 LUFS is the level Spotify plays back at, not the level this music is mastered to. So we measured 322 released tracks off the charts, one genre at a time, with EBU R128. Your demo is read against the median of its own genre, and against the quartiles either side of it.
A techno master sits at -6.8 LUFS, which is 7.2 dB louder than the level Spotify plays back at. Master to -14 and you hand that away; nothing turns it back up.
15 genres, 322 tracks. Drum & Bass is the loudest at −4.3 LUFS and Electronica / Ambient the quietest at −9.8, which is 5.5 dB between them. Measured from thirty second previews, which carry a decibel or two of noise on any single track: the median over dozens is what survives that.

What LUFS should my track be mastered to?
It depends on the genre, and it is louder than most guides say. Released Drum & Bass sits at a median of −4.3 LUFS and Electronica / Ambient at −9.8 LUFS; Techno at −6.8 and House at −8.8. The table above has all 15 genres.
Is −14 LUFS the right level for club music?
No. −14 LUFS is the level Spotify turns tracks down to when it plays them, not the level this music is released at. Every one of the 15 genres we measured is louder: even the quietest, Electronica / Ambient, sits at −9.8 LUFS, 4.2 dB above it.
What true peak should a demo have?
Below −1 dBTP at the very least. Spotify asks for that much headroom so the peaks between samples do not clip when the file is encoded for streaming, and −2 dBTP for masters louder than −14 LUFS, which every genre in the table is. The analyzer reconstructs the wave at 16 times the sample rate to find those peaks.
How were these numbers measured?
322 released tracks off the charts, 15 genres, 16 to 28 tracks each, integrated loudness to EBU R128. They come from thirty second previews, so any single track carries a decibel or two of noise; the median across a genre is what holds.
What you get back
Where the loudness sits against released records in your genre, and by how much.
What is still wrong, in the order worth fixing: dead air at the edges, a file name that does not read as Artist - Title, a low end that will not survive a big system.
Which labels it matches, and the reason each one matched: the genre and the BPM inside their window.
What moved since the last bounce of the same track, once you run it again.
