RØDE's RØDECaster Pro is a great, feature-rich audio interface for use with Ecamm Live. It can add some powerful features to your broadcast such as the ability to use the RØDECaster's sound effects pads and Bluetooth phone call-in.
Fixing Doubled Audio
However, some configurations may result in a doubled or echo effect in your broadcast for sound from sources other than your microphone. If you encounter doubled audio, follow these steps:
If you have enabled the RØDECaster's USB multi-track feature, you will see two audio interface's show up in Ecamm Live's Sound Levels window. Be sure to pick RODECaster Pro Stereo, and not RODECaster Pro Multichannel.
2. In the RØDECaster's on-screen settings, activate USB Mix-minus. To find this setting, use the RØDECaster's touchscreen, and navigate to Advanced and then to Audio and then to Processing. If you do not see these menu choices, ensure that you have the latest firmware from RØDE.
Once you have followed these steps, RØDECaster will no longer be looping the Mac's output audio back into the input.
Other Reasons for Echo
If you're still hearing an echo in your broadcast, you may need to activate Ecamm Live's Echo Cancellation.
If you're hearing feedback of your own voice coming from your speakers, ensure that you don't have Ecamm's Audio Monitor feature turned on.
