Push-to-talk is a concept where you hold down a key to talk, and let go when you're not talking. It controls the on/off of your microphone, making it act like a "walkie-talkie".

Why you want everyone to have this:

• Lets everyone use the regular roll20 interface without installing and setting up a complex extra program like Skype, Ventrilo, Teamspeak, Mumble or Discord.
  • Some of these types of program require hosting services, which adds even more complexity.
  • Most of these types of program are complex to set up, and would require lots of audio device fiddling and volume customization per-player.
• Stops the noise from that one player who types really loud, eats chips with their headset on, or has screaming kids in the background. You know the one.

However, this feature does not exist in roll20's voice chat.

Options are:

• Muting ones self when not talking.
  • But this is quite a lot of effort in conversation.
• Manually using the mic's mute feature.
  • Some microphones have a button for this, which is better.
• Using a program which controls your microphone mute feature.
  • This is by far the best solution.

One recommendation is http://www.pushtotalk.nu/

• Tested and works with Windows 10 64bit.
• Free, a tiny download, no installation required, trivial to configure.
• One recommendation is to configure its hotkeys as ` (backtick) and right-control. It turns out that right-control will permanently un-mute until backtick is pressed, which is technically a bug but really useful.

Even though it's additional work, ensuring that game policy has all players doing this very simple step will vastly improve everyone's playing experience. Please consider it for your game.

If anyone has another solution or program, please take a moment to post it here.
