John, I don't know what you can do. without hearing the noise it would be
hard to tell. I guess it will be trial and error.

Gary,
I'm using a new Allen -Heath Zed 10Fx mixing board with usb interface and
my cableing is brand new as well. My Win 7 I3, 8gb computer is also brand
new and I'm using Audacity 2.0.3. In a way I'm glad you don't think that
it is line noise interference. But how do I go about finding the
problem? Oh I forgot to mention that I'm using one of two new EV voice
quality mics and a Kurzwell K2600. Any suggestions on how I go about
finding where the problem may be is appreciated.
Thanks,
John

That doesn't sound like an AC line problem. If you had an AC line problem
you would hear a 60 or 120 HZ hum. it wouldn't be high pitched.
It may be noisy circuitry in your mixer, coupled with a cabling problem,
such as poor shielding or an impedance mismatch.

Subject: AC line filter question
Hi all,
I am experiencing some sort of high pitch line noise in my recordings.
I am using an Allen - Heath mixing board with a usb interface into my
Windows 7 computer using Audacity 2.0.4. I was told that I should look
into an AC line adapter, but I'm afraid that the entire electrical
system for tha room I am using is on one circut, including overhead
lights and fans. I wish to be able to get rid of this line noise that
exists even with the overhead fan off. Can anyone make a good
suggestion as to what I should do for this problem?
Thanks,
John
