http://mizage.com/shush/ for anyone on a Mac is a godsend. Emulates a hardware PTT (can be toggled to push to silence) before audio ever gets to applications. Best $5 I've ever spent.

What's so special about this? Discord has PTT and PTS native.

The reply is suggesting it as a solution to the problem for apps other than Discord, which the parent comment mentions.

AFAIK Ventrilo, TeamSpeak, and Mumble each support this

It's definitely common in gaming-focused apps, but not in the general or business focused apps like Skype, Slack, Teams, etc.

We use Teams on our team, and my current PTT technique is to Ctrl+Shift+M to unmute and mute every time. Très annoying.

Not to mention that often the mute button in many of these apps needs to execute hideous amounts of WebRTC-related Javascript in Electron, delaying your mute significantly. Signalling the CoreAudio OS system directly as Shush does is the right layer for the job.

IIRC even Skype has that option. Can you not bind this directly in Windows/macOS?

Skype only has "push to mute."
