Microphone out of phase

General discussion about Gig Performer
1

I have a mic hooked up to an x32 mixer which is also my audio interface. When monitoring the mic just thru the x32, it sounds fine. When running it thru GP and back to the x32 out, it sounds out of phase. I did check if I wasn’t running it double, which it didn’t. I broke all connections in GP and had no sound which confirms it didn’t run double on the x32, then I wired it from the audio in block directly to audio out block, both L and R, and it gives a phasing problem. It probably has to do with it being a mono signal that has to be to wired to both L and R to hear it in both speakers. I tried the “Gain and balance mono to stereo” block, and this also didn’t help. When only sending it to the left OR the right, it sounds fine.
Any ideas on this?

Thanks,

Stef

Keep in mind that using audio interfaces you introduce some latency.
Now when you use in ear monitoring you hear your natural voice inside your head and the sound coming from the audio interface.
Maybe that is the root cause of the issue.

I think this could not be the reason here as he says it sounds ok when he only uses left or right output only.
Latency will always stay the same regardless of using mono or stereo out.

Hard to tell what Stef is hearing here exactly, X32 routing could also be the problem.
Maybe he returns right and left outputs of GP into two channels on x32 and both of them are panned to mid position. So he “doubles” the mic signal in X32 software. That could sound like described.

what is the routing of the X32. I think you are right @DerBecker

I had latency problems when I routed the mic through GigPerformer :slight_smile: and the solution was to change the sample rate.

But if its only on one channel it should not this problem.

That doesn’t make any sense.

Why not, less smaple rate, less latency?

Higher sample rate less latency

You are right :slight_smile: Sorry!

Because I misread it. I thought we were talking about microphone out of phase and thought the suggestion of changing the latency was a fix!

You are sure that you are not mixing the output of GP with some kind of direct internal monitoring of the X32 itself? Digital interfaces always introduce some latency. If you mix the output of that with a latency free (analog) signal, you’re bound to have phase issues.

Just thinking out loud.

Thanks for all the help guys. This was what’s going on. There was a very small amount of latency which caused the sound to fase with my voice resonating in my head. The reason I didn’t hear it when only checking L or R, was because i cranked the volume way up for monitoring because it loses half of the volume when only checking one side.

Didn’t know it would be so hearable. The sample rate was on 64. A total roundtrip of about 6ms.
