Comparison uses a rolling RMS estimate and settles over a few seconds. Monitor level, mono listening and bypass do not affect export. A/B slots keep your edits during this visit; save a preset to keep them permanently. EQ and dynamics changes are audible immediately.

Master loudness

Momentary (gold) and short-term (green) LUFS over listening time, latest 15 minutes. Starts fresh with Play/seek or Reset meters; includes loops and setting changes.

Momentary — LUFS
Short-term — LUFS
Integrated — LUFS
Max true peak — dBTP

Measures the processed master before monitor volume, level matching, mono and bypass. Momentary: 400 ms. Short-term: 3 seconds. Integrated: gated loudness since Play or Reset meters, including repeated loops and setting changes. Export reports the complete file.

01 · EQ

Drag points to set frequency and gain. Select a bell to adjust its width. HP moves horizontally; set Low cut to 0 below to bypass. Arrow keys also move the selected point. Blue background: source spectrum (separate −90 to 0 dBFS scale).

Shelves shape the lows and highs; bells target a frequency region. Higher Q makes a narrower bell. Frequency and Q are saved with the preset.

02 · Dynamic EQ

Drag down to set maximum cut. Dashed curve: maximum combined cut. Green curve: current reduction. Arrow keys also move the selected point. Blue background: source spectrum (separate −90 to 0 dBFS scale).

Stereo-linked bell cuts respond only when the selected frequency region exceeds its threshold. Maximum cut limits the correction. Turn bands off individually to compare.

03 · Multiband compression

Drag the split handles or use arrow keys. Bars show current gain reduction in each band (0–12 dB).

Stereo-linked RMS detection. Crossovers affect phase; switch the whole module off for full bypass.

04 · Stereo

−1 · opposite polarity 0 +1 · mono

Correlation: —

Processed master before monitoring controls. Vertical = mono; horizontal = opposite polarity. Scope auto-scales for visibility. Correlation uses a rolling 1-second estimate.

1.0 preserves width; 0.0 folds to mono. Monitor in mono before widening. Mono sources remain mono.

05 · Output

Last 60 seconds: input sample peaks (gold), output sample peaks (green), ceiling (dashed). Lower strip: peak gain reduction (0–12 dB). Each point summarizes about 100 ms, not individual transients.

Limiter reduction: 0.0 dB

Output peak: —

5 ms lookahead with 4× reconstructed true-peak detection and 0.3 dB safety margin. Export checks reconstructed peaks again and reports any extra protection. Preview and export share the processing chain.

Each save creates a new preset version in this browser. Custom presets stay in this browser and are not synced to your account. Export captures the current settings; you can keep listening while it renders.
