Measured, not modeled

YOUR EARS LIE.
NUMBERS DON'T.

Most tools guess from metadata or vibes. We run real signal analysis on your actual audio file — every number ships with a measured badge.

Key

How it works

THREE STEPS. ZERO GUESSWORK.

Upload

Drop in an MP3, WAV, or M4A — up to 25 MB. A full track or a mix bounce, both work.

We measure

Real DSP reads your file in seconds: tempo, key, loudness, energy, groove, brightness.

Get The 75%

The 75%

DATA IS CHEAP.
DECISIONS AREN'T.

Most analyzers drown you in graphs. We compare your measurements against your genre lane's targets and rank the moves that matter — up to four, ordered by impact. It's the 75% of the work that gets you 75% of the way there.

  2. 2. True peak at +0.8 — pull the limiter back 1.5dB.
  3. 3. Brightness dips after the drop — automate a high-shelf lift.

FAQ

STRAIGHT ANSWERS.

No. Your audio is uploaded for analysis and deleted immediately after. Your measurements and results are saved to your account so you can revisit them — the sound file itself is gone.
Real DSP on your actual file: tempo (BPM), musical key (Camelot), loudness (LUFS integrated + true peak), energy, danceability, and brightness. Every number carries a measured badge — never an AI guess dressed up as data.
MP3, WAV, and M4A up to 25 MB. A full-length track or a bounce of your mix — both work.
We suggest one of 14 lanes (Trap Soul, Drill, Afrobeats, House, Amapiano…) from your tempo and energy, and you can pick your own. Each lane has its own targets, so The 75% always compares you against the right reference — not some generic “industry standard.”
After measuring your track, we rank the highest-impact production moves for your numbers — up to four, ordered by impact. It's the 75% of the work that gets you 75% of the way there, before the endless tweaking.
Anytime, in one tap from your account page. You keep unlimited scans until the end of the billing period. Single-scan purchases are yours forever.
