I had the issue of getting multitrack recording to be in sync. Recordings did not line up and it was driving me mad. I researched it online and found out that this issue has to do with I/O Buffer Size settings.

In this video I show how I updated mine. I am using an iMac with Adobe Audition and a Behringer U-Phoria IMC22.


Go to Preferences, Audio Hardware, Change I/O Buffer Size to 128, Sample Rate of 44100, I unclicked “Use machine-specific device defaults” incase this resets these settings on restart.


My recordings line up now and I can get back to recording now!! Cheers.
