What sort of mics?
SM 58
Positioned how far from the people speaking?
They talk right into it.
Did you listen to each microphone as a single mic or were you listening to the mix of both mics?
Mix of both mics.
Did you mix to mono on site or recorded them as separate tracks and then mono’d them in post prod?
On site.
Have you ever tested your mic cable wiring are they correct ie; pin 1 to pin 1, pin 2 to pin 2, and pin 3 to pin 3?
They are three pin xlr cables they are plugged in correctly.
Are they pro made cables or DIY cables?
Pro made and tested.
Also when monitoring the audio it sounded fine.. just in playback on the computer one sounds tinny for some reason.
My gut feeling is it a 180deg phase problem, if you still have the recording as 2 separate tracks phase reverse just one track (either one … ) then try to mono mix it and see if that makes a difference.
I just recorded to one track I believe…. maybe il figure out how to do two from now on… what is phase 180?
Thanks for your help hopefully these answers help you to determine what is wrong.
