Sound Field

A spatial map of a stereo song: frequency rises, time recedes, panning spreads left-to-right, and loudness becomes opacity.

DisplayMinimum loudness −96 dBFSPoint size 75%

Frequency rangeLow frequency 35 HzHigh frequency 18 kHz

Frequency balance—low ↔ high percentile

Stereo balance—energy-weighted lean

Volume rank—versus this song

Balance snapshot uses the two-second window around the playhead. It is a navigation aid, not a mastering target.

Advanced indicators

Stereo correlation—−1 phase risk ↔ +1 mono

Stereo width—side energy share

Dynamic punch—crest factor

Low-end width—side energy below ~120 Hz

Professional engineering

Advanced measurements begin automatically after the visualizer is ready.

Standards-oriented level

Momentary—400 ms LUFS

Short-term—3 s LUFS

Integrated—gated LUFS

Loudness range—LRA

True peak—4× reconstructed

Sample peak—decoded PCM

BS.1770-style gating; true peak is 4× reconstructed browser analysis, not a certified compliance meter.

A/B comparison

Load a B mix to compare loudness, width, crest factor and tonal centre at the same relative position.

Named sections

Set the inspection-region boundaries, name the section, then add it.

Filtered region audition

Uses the current frequency range and inspection-region loop. Filtering helps identify suspicious energy but does not isolate instruments.

Inspect warnings

Load a song to run cautious engineering checks.

LUFS-I (estimated)—approximate

Decoded sample peak—not true-peak

Rendering—rendered / eligible

Colour guide

Mostly left Near centre Mostly right

These colours show stereo placement—not instruments. True instrument colours need stems or AI separation.
