I use my earphones to monitor my audio.It sounds like it is your guitar picking up interference from something, like your pc monitor. I say that because the buzzing sound is gated (and actually, it is the right frequency for a monitor - I get it all the time. If I need to stand near the monitor while recording, I turn the guitar 90 degrees, as in face another direction, then the buzzing stops).
NoAre you going through any outboard effects first before the interface?
YesAre you straight into the interface with software amp/ effects?
Yeah, its the inbuilt metronome that Garageband has. I don't think its the problem but I'll still check. Coz the buzzing is there when I.m not recording tooIs that popping a metronome or part of the interference? (I'm not being dim - I'm just not sure it is a metronome).
Yeah, a standard CFL versionFluorescent light nearby? Incandescent or LEDs don't create hum, I think. A monitor shouldn't either, unless you're still using a CRT.
My phoneBluetooth or wifi devices nearby?
Cool thanks!!!I used to get him from somewhere. I could never figure it out. At a time when Radio Shack was open they sold me a cable that had rca jacks on both ends and in the middle there is this thing that looks like a battery. I put 1/4” converters on the rca jacks and it eliminated the sound. RS is gone but if you google hum eliminator they might be available or some other product to eliminate hum. This didn’t affect recording since the humming was post recorder (my Mac). I still use one today. Give it a shot, I’m sure you’ll find something similar.
