If you hear an echo during a live Studio session or in a recorded track, it may be due to a participant's audio setup. In most cases, the echo is fixed by wearing headphones or enabling Echo Cancellation, but for more ways to minimize an echo, see the troubleshooting suggestions below.
Enable Individual Echo Cancellation
Each person's Echo Cancellation is usually already set up in the Lobby. Before they enter the Studio, they indicate whether they are wearing headphones. You usually won't need to change it afterward in the Studio, but if everyone other than one participant hears an echo, enable that participant's echo cancellation in the sidebar.
There are additional possible causes for an echo, including audio spill (also called or bleed/leakage) and crosstalk (more info) where a microphone records audio from an unintended source. See below.
Headphones plugged into a USB microphone
If you or your Guest's headphones are plugged into a USB microphone and the microphone's gain (audio sensitivity) is high, other participants' audio may get recorded through the mic and captured on the track.
To avoid this, plug the headphones directly into the computer/device rather than into the microphone.
Headphones with an in-line mic plugged into the AUX/headphone port
If you or a Guest are using a computer with headphones plugged into it, the computer may use the in-line microphone (in the headphone's cord) as the default microphone. However, this sometimes causes an echo.
To avoid this, select your device's built-in microphone, like the MacBook Pro Microphone (Built-in) as shown in the image below. The first option on the list, Default – External Microphone (Built-in), is the microphone in the headphone's cord.
If this isn't possible or the computer does not have a built-in microphone, reduce the microphone's sensitivity using the computer's settings.
Use the mix-minus mode on an audio mixer
If you or a Guest are using an audio mixer, make sure to enable Mix-Minus to isolate the input audio signal from the output audio coming from the Studio. Read more about isolating tracks with an audio mixer.
