Sources, filters and outputs as cards, connected with cables. What you see is what you hear.
01 — Routing
Your Mac as a patchbay: apps, microphones and outputs are cards, connected with cables you patch yourself. One signal flow, three views — vertical cables, horizontal cables, or a matrix crossbar.
Cables = truth
The microphone runs through “clean voice” — and from there into the stream and onto your headphones.
Music passes the EQ and automatically ducks while you speak — ducking per source.
The game stays loud and unfiltered on your headphones, but goes to OBS as its own track.
Spotify, Safari tabs, microphones, full system audio — every source becomes a card. Direct sound is muted cleanly: no echo, no doubling.
A filter splices itself into the cable — and when removed, the connection stays. Live, with no dropout in the signal.
Speakers, headphones, OBS tracks, AirPlay, multi-output groups — simultaneously, with its own level per destination and a monitor path per track.
02 — Filter
Every filter has a clear name, exactly one main knob — and real studio tools underneath. Want more? Every installed Audio Unit plugin runs in the chain too.
Evens out quiet and loud passages — for a dense, consistent voice.
Distance changes, guests differ in volume, you turn away for a second — the compressor keeps the voice in its lane before anyone notices.
Evens out quiet and loud passages — for a dense, consistent voice.
A safety net — catches peaks before they clip.
Cleans up the low end and lifts presence. One knob = intensity.
Boosts the foundation of your voice — fuller, warmer.
A touch of room — keep it subtle, or it sounds like a bathroom.
Delays the chain — compensates e.g. video latency (lip sync).
Filters out mains hum (50 Hz + harmonics). Knob = how strongly.
Separates your voice from the surroundings — right on your Mac, no cloud.
Shifts the pitch — center = neutral, up to ±2 octaves.
Against harsh S and sibilant sounds. Knob = how strongly.
Silences the pauses between sentences. Knob = threshold.
Makes the voice loud and dense — broadcast sound at a stroke.
Removes noise floor from any signal — music and records too.
Full EQ with curve and live spectrum — drag bands freely.
03 — Equalizer
The built-in parametric EQ: drag bands freely across the live spectrum, each band with its own colour, solo it on headphones and check with A/B. The curve is exactly what the engine computes.
04 — For streamers & squads
Until they end up in your headphones. NoicePatch cleans up other people's voices too: Discord, game and PS5 chat run through the same filters as your own microphone.
Filter noise, hum and room echo out of incoming voices — Voice Isolation and denoising work on any source, not just your own mic.
Your own ducking per source: as soon as someone speaks in voice chat, game audio and music dip smoothly — and come back when it's quiet.
Mic, game, music and chat as their own channels on the virtual device — up to 8 stereo tracks, cleanly separated in recording and stream.
⌥⌘M mutes all microphones system-wide — as a global hotkey, in the menu bar and on the Stream Deck.
Running PS5 or Xbox chat through your Mac? It passes through denoising and the gate too — and lands cleanly in your stream while you monitor it.
No cloud, no subscription, no forced account: all processing runs locally in real time — even offline at LAN parties.
A real chain from the app: “Clean Voice” — Voice Isolation + hum removal + de-essing, live in the signal path.
Scenarios
Two mics on arms, a guest via Zoom — every voice on its own track, with gate and compressor already in the recording. The multitrack lands in your DAW while everyone monitors latency-free.
Mic → clean voice → DAW track 1 · Zoom → denoise → track 2
Mic, game, music and Discord as separate OBS tracks — viewers hear the music quieter than you, the squad gets denoised, and the cough button lives on your Stream Deck.
4 sources → filters → stream mix (OBS) + headphone mix — independent levels
Webinar, band rehearsal or vinyl digitizing: every source cleanly leveled to studio monitors AND as a multitrack recording — with denoising for old records and a safety limiter.
Inputs → denoise + limiter → studio monitors + recorder
Menu bar
The menu bar panel shows every patch with power, master and live meters — inputs, outputs and groups included. Switch the scenario, pick the system output, save a profile: all without opening the main window. Prefer a clean menu bar? Turn the icon off in Settings — NoicePatch stays reachable from the Dock.
05 — Stream Deck
The NoicePatch plugin brings live meters, levels, mutes and fader strips to your Elgato Stream Deck — with its own canvas that builds every tile from blocks. Everything below is rendered live by the real plugin engine. Nothing is a mockup.
Every key renders its own meter: LED or smooth, with a ghost level before the filter and a peak marker — straight from the engine.
Two or three keys become ONE fader: up is louder, down is quieter. Level, target and peak run across the whole strip — vertical or horizontal.
On Stream Deck +, turning sets the level, pressing mutes — the touch strip shows four channels side by side, as arc, bar or full meter.
Left, center, right and long-press of every key get their own actions — mute, reset, level steps or patch start.
Source, output, channel, route, filter chain or a whole patch — even hardware DSP like the Shure MV7 sits right under your finger.
A construction kit for every tile: stack blocks, drag values, live preview for active, muted, hold and offline — global or per key.
Stream Deck — Canvas
The canvas builds every tile from blocks: meter, value, name, label, zone. Each block has its own controls instead of a fixed style — and the preview runs on the same engine that drives your deck.
Try it
The canvas wants a mouse: blocks get dragged, and the handles on the tile are a few pixels wide. On a desktop it sits right here, ready to try.
06 — Engine
As soon as you speak, the music dips — smooth, two-stage filtered, adjustable per source.
The leveler keeps your voice at target loudness — lifts quiet parts without pumping up breathing pauses.
Shure MV7 connected? Gain, monitor mix and its built-in DSP are controlled right from the card.
Drift-compensated clock, a start watchdog against dead devices, live graph changes without audio gaps — native CoreAudio, no fragile system extension.
NoicePatch separates voice from keyboard, fans and room echo — fully local, on any source.
The noise gate only passes what's above the threshold — breathing, fans and keyboard stay out.
The compressor pulls everything into an even band — your voice stays dense no matter how close the mic is.
Up to 8 stereo tracks per device — mic, game, music and chat land separately in OBS and your DAW.
And beyond
