ANY APP WITH A MIC MENU

Play music to podcast guests

Put your mic and your intro music in one input, then pick Patch Mix in Discord or Zoom. Guests hear the show as it plays, never their own voices echoed back.

Show clips in a class

Play videos from Chrome into a Zoom workshop without sharing your screen’s sound. Rehearse the level in your headphones before the call hears it.

Demo an app with its sound

Let people hear the product, not just see it: alerts, playback, voice features. Your narration and the app arrive as one clean input.

Stream with one clean input

Give OBS a single source with your voice and your game or browser at the levels you set, with a limiter keeping peaks in check.

Bring in any app with Pass-Thru

Apps that let you choose a speaker, like a DAW or a soundboard, can play into Patch Pass-Thru and on into your call.

Cue tracks in private

Turn Send off and Hear on, and a source plays only in your headphones. Line up the next track while the call hears just you.

Mix

You decide what the call hears.

Mic plus four apps

One microphone and up to four apps, each captured on its own.

Send and Hear, per source

Put a source in the call, in your headphones, or both.

Levels and meters

−60 to +6 dB per source, a master fader and stereo meters.

Preview before going live

Hear the whole mix while the call hears silence.

Scenes

One setup per kind of call. Switch mid-call and shared sources keep playing.

Menu-bar control

Mute, switch scenes or stop with the window closed.

Protect

Guard rails for live calls.

−1 dBFS limiter

A fixed ceiling on the way out, with a light that shows when it’s working.

No echo for guests

The call app’s own sound is kept out of the mix.

Never swaps your mic

If your mic drops, the call hears a pause, not your laptop mic.

Headphones out, sound stops

Local listening pauses, so a clip never blasts from your speakers.

Updates wait

An update never installs in the middle of a session.

Questions

Which apps can I send audio into?

Any Mac app that lets you choose a microphone. Patch includes guided setup for Zoom, Google Meet in Chrome, Discord and OBS.

Can I send just one browser tab?

Not yet. An app source includes all its tabs and windows. Run the call in one browser and play clips from another.

What happens when trial time runs out?

Nothing drops. After 20 minutes of a session, a low hiss is mixed into what the call hears until you stop. The next session starts clean.

Does Patch record or upload audio?

No. Nothing is recorded and your audio never leaves your Mac. Captions are optional, made on device and never saved.

Will installing it interrupt a call?

Installing the audio component pauses your Mac’s sound for about a second. Do it between calls.

How do I remove it?

Settings → Uninstall removes the app, its audio component and the Patch Mix device.
