I'm using Ableton Live 11 Lite while recording a cover, and discovered that all of my recording comes out as a jittery mess all of the sudden. I'm using a Focusrite Scarlett Solo, a Squier Telecaster, Maestro Ranger Over-Drive pedal, and an Audio-Technica Mic. It's a new project, I have a metronome set up for recording Privately Owned Spiral Galaxy, and the audio interface splits the mic and guitar into separate tracks that I'm trying to record individually. I posted a sample of the God-awful sound of it recording here for reference.
P.S. I know this isn't the correct page but there's hardly any Ableton/DAW questions on the Music page and no answers really, as opposed to the several I found on SO.
I would start with playing with your buffer size in your Audio driver.
