Doesn't matter which - just total system gain.  That= S/W works best if the noise threshold rides at about 10dB above the baseline,  th= en it allows for up to 70 - 80dB of signal peaks.

Alan,

When you wrote :-

my only comment is that you may have too much gain in the system.

Are you meaning sound card or receiver gain?

Gary.
