I thought so- I believe you having the same sample rate up and down conversion
issue that I was having on digital modes, and that 44.1 k is not where you want
to be. See if you can find out what sample rate N1MM uses for its audio files.
Record the wavs at a multiple of that sample rate. I "forced" the VAC sample
rates and the Windows sample rate to a multiple of the sample rate used in one
of my digi programs. Since many Flexers use N1MM, they can contribute the
sample rates for their wav files and for VAC.
