So I decide to give up and set the audio level right.
So I get the free for private use sound card oscilloscope
http://www.zeitnitz.de/Christian/scope_en.
I picked this one because it was first when I goggled "sound card
oscilloscope".
Very nice.
But gee, there are 2 channels for the mike and a balance control.
One channel has "the signal" one channel has "chaff".
So I set the balance control to kill the "chaff".
I then raise the volume in the K3 line out until it flat tops
and I back it off by 2.
next step, get it to sample at 48000.
obsessive, I am.
