Getting started…
How it works — three steps
1
Drop your mix
Any format works — WAV, FLAC, MP3, or AIFF. For the most accurate true-peak reading, use your lossless master rather than a decoded MP3.
2
Add a reference (optional)
Drop a commercial track you want to match. RefTrack level-matches it automatically so the spectrum comparison is a fair read — not a loudness trick.

Streaming Readiness

Is It Ready for the Platforms?

Streaming services automatically adjust volume — if your track is too loud, they’ll turn it down, which doesn’t help you. Physical media and broadcast don’t auto-adjust the same way, but they have their own loudness conventions worth hitting. Here’s how your track sits against each target.

Loudness Over Time

How Does Volume Change Through the Track?

Short-term loudness (3-second windows) across the track. Orange = your mix; blue = reference. Dashed lines show common streaming targets.

Phase Correlation Over Time

Where Does the Stereo Image Change?

Values near 1 = healthy mono-compatible stereo. Near 0 = very wide. Below 0 = phase cancellation — will sound hollow on a single speaker.

Healthy (>0.7)
Wide (0.3–0.7)
Phase risk (<0.3)
Tone Balance — 31-Band Spectrum

What Does the Frequency Balance Look Like?

31 1/3-octave bands — the same resolution used in professional mastering. Orange = your mix; blue = reference (level-matched). The lowest bands (≤31 Hz) are shown hatched: a single FFT can’t resolve them precisely, so treat them as indicative only.
