So I have a basic audio interface (scarlet 2i2) and a shure sm57 microphone that uses an XLR cable. But when I screen record with quicktime it records to just one channel (the left channel) through my mic. Because my microphone is connected to just one of the XLR inputs on the interface. So it's just recording on that one channel (and there's no way to change it in quicktime), so when I play it back I can just hear it in one ear.
So I was wondering if I should buy some kind of splitter that basically converts my microphone into two inputs so that both channels are recorded simultaneously and then it'd be in stereo? online I saw it's called a "XLR Female to Dual XLR Male Y-Cable".
But wouldn't that degrade the sound quality of the mic or is it ok to do this?
p.s alternatively I could extract that audio from my recording and convert it via software from one channel into two channels. but I think I prefer the hardware solution because it's one less step.
Edit: just got this Y splitter cable and it works perfect on both my dynamic and condenser xlr mics.
Edit#2: found a software solution that converts it from one ear to two ears so don't need to use the y-splitter anymore.
