Geyser Mastering

Move the pointer (or touch the graph) to read the frequency, the nearest note and the level.

Long-term average of the output compared with the average of the loaded Reference (level differences are removed, only the tonal shape is shown). Bars above the line = the output has more energy in that band than the Reference.

Correlation and width for Low / Mid / High. A negative correlation in the lows usually means the bass will weaken (or vanish) in mono.

PLR = true peak − integrated loudness. Below about 6 dB the master is very squashed; a tall bar at 0 dB means the waveform is being clipped.

These tools edit the audio itself — use Undo to go back.

Drag on the waveform to select a region, then edit it.

8-band parametric EQ: every band has its own frequency, gain and Q (band 1 = low shelf, band 8 = high shelf). Runs after the EQ / FILTER above.

Cuts or boosts only the content that exceeds the threshold in each band.

Match Main toward the Reference spectrum. Load a Reference track first.

⚠ Reference not loaded — Match EQ is unavailable until you load a reference track.

Not analyzed

Three phase-coherent bands (Linkwitz-Riley 4th order). Each band has its own compressor; attack / release are tuned per band (slow lows, fast highs).

Eight phase-coherent bands (Linkwitz-Riley 4th order), each with its own compressor. Move a crossover to change where a band starts and ends; attack / release are tuned per band (slow lows, fast highs).

Final-stage loudness maximization. Margin is True Peak headroom.

Bass Mono folds content below the cutoff to mono. Low / Mid / High width use a phase-coherent 3-band split (150 Hz / 3 kHz, or the Bass Mono frequency); they are multiplied with the overall Width.

Finds clipping, inter-sample overs and over-compression caused by your effects, then lowers the effect amounts (EQ boosts, makeup gain, drive, saturation, widening, maximizer drive, gains) by the smallest amount that clears the problem. Cuts, thresholds and the limiter ceiling are not touched. Undo restores everything.

Output peak (dBFS) · red = clipping · dashed = true-peak limit

Analyze Reference and auto-apply only the modules you select.
Load both Main and Reference first.

⚠ Load Main + Reference before running Auto Master.

Compressor and Limiter start OFF. If left unchecked, they will be force-disabled including any existing settings.
