Features

Technical Capabilities

Bass mono-maker: everything below an adjustable cutoff (20-500 Hz) sums to clean mono - elliptical M/S filter, mid signal untouched

Gain (±24 dB), resonant-free high-pass and low-pass filters

Stereo width 0-200%

Click-free polarity flip and mute

Lightweight CPU footprint, zero latency

Clean, minimal interface

Mono Maker

Mono where it matters

Low frequencies carry the most energy in a mix, and out-of-phase low end wastes headroom, wobbles on vinyl, and falls apart on club systems and phone speakers. The MONO knob solves this the mastering-grade way: everything below the cutoff collapses to clean mono while the rest of the stereo image is untouched.

Below the cutoff

Summed to perfect mono. Kick and bass hit from the center on any system - tighter, louder-feeling low end.

Above the cutoff

Your stereo image, exactly as you mixed it. Width, reverb tails and doubles stay wide.

The mono sum

Never touched. The filter only removes side content, so mono playback is identical by construction - nothing to check, nothing to fix.

How it works

Elliptical M/S filter

The signal is split into Mid (what mono listeners hear) and Side (the stereo difference). Only the Side is high-passed - the same technique mastering EQs use for vinyl-safe bass.

Before Width

The mono-maker runs ahead of the Width control, so your lows stay locked to mono even at 200% width.

Always clean

No crossovers, no band-splitting phase smear, zero latency, no bypass clicks. At OFF the filter sits below the audible band.
