Monofilter

NUGEN Audio Monofilter is a bass management plugin that brings low frequencies into mono while preserving stereo width higher in the mix. By focusing the bottom end, it helps bass-heavy tracks feel tighter and more defined, with low-frequency content better suited to loud playback. Use it on mixes headed for clubs, where stereo bass can behave unpredictably across a room, or when preparing a master for vinyl, where excessive bass width can cause cutting and playback problems. A stereo width envelope, high-pass filter cutoff, and separate mid and side trim controls let you shape the result. Stereo spectrum analysis and phase correlation control help you assess and manage the signal, while Zero Latency, Linear Phase, and HQ modes offer processing options. Monofilter suits producers and mastering engineers who want a more controlled low end without collapsing the entire mix to mono.
