Erroneous high pitches in NES sound emulation

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Play a nes game like megaman 2

What is the expected output? What do you see instead?
I have very good speakers (and ears), and there is a lot of very high pitched 
notes during emulation.  It seems to happen when one of the channels is not 
playing a scheduled note.

What version of the product are you using? On what operating system?
BizHawk 1.0

Please provide any additional information below.
Perhaps until the sound emulation is fixed, a lowpass filter might be a good 
idea, ie, disallow sound output of frequencies higher than X.
