Does anyone know why whatever mic or preamp i use to record through my digital performer(motu) system, i am also getting a grainy top end sound on the vocals mostly. It almost sound like im recording the level too hot or something but im definetly not. its just sounds kinda fuzzy.

any body know why?
 
bring up your buffers a little, if they are set too low then that can cause a distorted sound. Driver problems are the only other thing i can think of. Has the unit worked in the past?
 
thanks fo the info, it kinda always seemed to have that coating of fuzziness on it. Its digital performer maybe.
 
More likely - poor quality converters -- what soundcard are you using?
 
i am actually converting the signal from anolog to digital using the apogee psx 100 then into motu 308 using aes. then i am converting again from digital to analog using another apoggee ad8000. The software is digital perfomer using a g4 dual processor macintosh.

You should NOT be hearing anything grainy at all... there must be something mis-wired/misconfigured somewhere... how are you clocking everything?
 
im using the nanosync masterword clock. 44.1/16 bit. do u think it could be something with digital performer/?????
 
sounds like a motu driver problem to me, or your settings in digital performer are messed up. try reinstalling the soundcard?
 
I was running a mix off a roland workstation today via the coaxial digital output into cubase and noticed a very similar problem. Turned out to be that the Roland was putting out 44.1K, and I think my RME soundcard was trying to be the master clock at 48k , and the cubase project was recording it at 48K. ( OK, I was not paying a whole lot of attention to this mindless transfer...!) Once i noticed it, I was somewhat surprised it even locked up and passed the signal, but it did and it also put a funky alias into the top end just like you've described. It may be a longshot, but I'd check closely the sample and bit rates throughout and make sure all components are speaking the same language.
