Hey guys,
I've noticed this noise is getting louder. Not sure what it is

when I press the clutch pedal in, the noise stops. When I release it, the noise comes back. Initially I thought torque tube bearings, but could it be the clutch throw out bearing? Anyone have a similar problem? Note due to the phone microphone it is MUCH louder in the recording for some reason. It can only be heard when stopped / not driving, meaning it goes away above 2k rpm. Any ideas?
