Setting Up Audio
Setting up Aggregated Audio Devices in OSX
The built-in audio interface in Mac OS X is presented to music programs as several drivers: one for the outputs, one for the line input, and one for the built-in mic, and Record can only access one audio driver at a time. To use your built-in audio interface you will need to create an aggregated device.
How Do I Optimize Audio Performance in Record?
You generally want the lowest possible latency when playing an instrument in Record in real time. However, selecting too low a latency might result in playback problems (clicks, pops, dropouts, etc.). The procedure for adjusting latency can differ depending on your audio card, driver and your operating system.
How Do I Monitor in Record?
Record offers a few options for monitoring incoming audio. Open the Record Preferences and look in the Monitoring section on the Audio page to set the way in which monitoring is handled.
