Re: Pink noise filtering



Could the noise be generated from I/O lines of the pre-amp, say if they crossed power cables or near computers/screens? Processors can make a pitch variable noise, depending on what they're doing, and some CRT screens create high pitched noise. It's certainly best to fixed problems at the source,

Laters,

Subject: Pink noise filtering



I've been searching around trying to find a way to get rid of some pink noise from a USB audio input device, comprising the sampling unit and a pre-amp for phono recording. The pink noise is only generated when the pre-amp is in use.

I've found plenty of algorithms for the creation of pink noise, however precious few for the removal of same. I am not a DSP expert and I was wondering if anyone would have some idea as to what direction I should take in resolving this issue. Is there an easy way of filtering the noise out?

Thanks,

\tommy
