Clipping of a recording

Post by BM_Radio_Players » Thu Nov 29, 2018 11:21 pm

I have recorded a radio play using 6 mics and a stereo SFX using an R16.

I have done this successfully many times but this time I am experiencing "clipping" of voices on all the voice tracks. They suddenly start and stop for short periods, maybe 130 - 150 mS. I first thought it may be clipping from high levels, but from what I read in the manual high levels only result in distortion not in the recording being clipped, and it doesn't seem to be in places of high level anyway.

I can hear the unclipped portion of the words at very low level on the adjacent mikes, so it only seems to affect one track at time.

This recording is ruined, but I don't want it to happen again.
Any ideas out there of what could be the cause?

Regards

"Clipping" IS "Distortion".

There are three places where clipping/distortion can be introduced, though the third is least likely (master fader level too high for the mix).

PEAKing (input gain control is set too high causing clipping in the ADC stage)
Insert Effect Output level too high (resulting in clipping of the processed signal, even though the input PEAK was correctly set)

Wasn't anyone monitoring during the recording? They should have heard any problems with enough time to attempt corrections.
