Be heard. Not your background.
Tish NC turns down keyboard clatter, fan hum and room noise in your microphone. The cleanup runs on your computer, and the people on the call hear your voice.
Off: the call gets everything your microphone hears.
The background steps back. Your voice stays.
-
Keyboard.Typing while you take notes on a call.
-
Fan.The steady hum of a laptop, a cooler or the air conditioning.
-
The room.Dishes, a TV through the wall, the neighbour's dog.
- Your voice.
It stays. It's what the other side should hear.
Results depend on your microphone and surroundings. People talking near you may still be heard.
Calls from home
Work meetings in Zoom, Google Meet and any other app that lets you pick a microphone.
Shared offices
When people nearby type and the equipment hums.
Games and streams
Discord and OBS get a microphone that's already clean.
Set it up once.
Tish NC sits between your real microphone and the call. You pick its microphone in the call app, and the rest happens on its own.

Cleanup on your computer
The noise cancellation models ship with the app. Microphone audio is cleaned on your computer and is not sent anywhere. On Mac you can choose the Neural Engine or the CPU.

Questions
Which computers does Tish NC run on?
Macs with Apple Silicon and macOS 15 or later, and computers with 64-bit Windows 10 or 11. Intel Macs are not supported.
Which microphone do I pick in Zoom, Meet or Discord?
On Mac, Tish Audio. On Windows, CABLE Output. Tish NC takes your real microphone, cleans it and passes it to that virtual microphone.
Does my audio go to the internet?
No. Noise cancellation runs on your computer and the models ship with the app. Tish NC goes online to activate the licence once and to check for updates.
Can it clean up the other people on the call?
On Mac, yes, if you want: set Tish Audio as the speaker in your call app and turn on “Clean up incoming audio” in Tish NC. The Windows version cleans your microphone only.
What is Tish Audio?
The audio driver that carries clean sound from Tish NC into your call apps on Mac. If it is missing or out of date, Tish NC tells you.
How can I check the result before a call?
On Mac, open Test Lab in Tish NC (⌥⌘T). Record your own voice or use a demo voice, add noise such as a cafe, the metro or a keyboard, and compare the sound before and after.
How is Tish NC different from Tish?
Tish NC does one thing: it removes noise from your microphone, and on Mac optionally from incoming audio. The full Tish for Mac also records meetings, transcribes them and writes summaries.
