AV Monitor

AV Monitor is a macOS app that lets you quickly preview your audio and video devices. Whether you’re preparing for a video call or just want to test a device, AV Monitor is the tool for you! Getting started is incredibly simple: choose a video device to display in the window, choose an audio device to output, and that’s it. You can change the video device’s output resolution and frame rate, but AV Monitor defaults to the max settings for both.

Featuring:

• Simple audio and video device selection
• Ability to switch to any resolution and frame-rate supported by your video device
• Audio device volume adjustment
• Ability to preview multiple devices in separate windows
