Spectrum
01 · Equalizer
Five bands, ±12 dB — the response curve is computed live from the filters.

Glue and control — watch the gain-reduction meter breathe.
02 · Exciter · 04 · Image
Harmonic warmth and mid-side width.
05 · Output
Final gain into the safety limiter.
True-peak safety limiter · always on · ceiling −1 dB
Five stages, one signal path
Every knob above drives a real Web Audio node. The signal flows through the same chain a mastering engineer would patch — and the A/B button lets you hear exactly what it's doing.
Equalizer
Low shelf at 40 Hz, bells at 160 Hz, 640 Hz and 2.5 kHz, high shelf at 8 kHz. Sculpt the balance before anything else touches it.
Exciter
Soft-clip saturation blended in parallel — adds harmonics, warmth and perceived detail without raw distortion.
Compressor
Threshold, ratio, attack, release and knee. It evens the dynamics and glues the mix into one piece.
Stereo image
A mid-side matrix widens or narrows the field — from mono-check at 0% to cinematic at 200%.
Limiter
A fast brick-wall stage holds true peaks under −1 dB, so the master is loud and streaming-safe — never clipped.
