Push-to-talk microphones are useful for avoiding feedback while streaming and conferencing simultaneously in an Evercast session. Here's how to make it work.
From the lobby, click the Settings button.
In a live room using Evercast for Mac or Windows, hover over your name in the top right of the screen. In the menu that appears, click on Device settings.
In a live room using Evercast for Chrome, find the More button on the bottom right, then click Device selection.
In the window that appears, go to the Microphone drop-down and select your push-to-talk microphone. The name of your microphone will vary by the brand and model.
Verify that your microphone is working by talking into it and watching the Microphone level audio meter. When you see the colored bar move, you're good to go! Click Save.
You can also set a shortcut key in the Push-To-Talk Shortcut popdown.
