WIDE

Stereo width that holds up in mono.

Allpass decorrelation across 40 ERB-warped bands, with per-band correlation feedback that keeps every frequency mono-safe. Expand without phase collapse. No Haas tricks.

What makes WARM different.

01 / Psychoacoustic width curve

• Width follows human perception of stereo across frequency. Most expansion where your ears are most sensitive. Based on perceptual research.

02 / Three stereo modes

• STEREO for natural width. M/S for mid-side balance. HAAS for delay-based widening. Each mode uses different psychoacoustic strategies.

03 /  Mono-compatible by design

• Per-band correlation feedback keeps every frequency safe for mono. The MONO button lets you check instantly. No phase cancellation surprises.

04 / Frequency-focused expansion

• The FOCUS knob targets width to a specific frequency range. Expand just the highs, just the mids, or the full spectrum.
