SIGNAL CHECKFree online mix analyzer. Check your mix or master in the browser.

How loud your track is overall, and how far streaming platforms will turn it down to hit their target.

The balance of lows to highs across your track, which tells you whether it leans dark, bright, or even.

How wide your mix sits across left and right, and whether that width survives when it collapses to mono.

The gap between your loudest and average moments, which is what makes a track punch instead of feeling flat.

Whether your peaks push past the ceiling, the point where some playback systems start to distort.

Narrow ringing peaks from 1 to 8 kHz, shown in four lanes. The score grades the middle two, 2 to 5 kHz, the zone that makes a mix tiring over time. Separate from the HIGH-MID level above: that band can sit on target and still ring at one frequency.

A plain checklist of whether your track is ready to release for the context you picked.

The identifying details of the track: tempo against the genre you picked, key with its Camelot code, how busy it is, and how human versus programmed it reads.

Tempo and key are estimated from the audio, so confirm them by ear before trusting them. The feel score reads how much natural human variation is in the take: spectral richness, harmonic irregularity, and timing. Loose live playing scores high; tightly quantized or synth-driven tracks score lower. A lower score is about character, not quality.
