[UK-CONTEST] DVK Audio Quality

[Chris Burbanks]

Hi Robin. I've been playing around with the various gain levels and it's
looking better. I suspect I am not going to be able to improve it any more.
An interesting learning curve but not during a contest! I'll take a look at
that site after. 73 Chris

Well I guess an overall increase in gain of 10db would have created the
same effect ! IS this just a lack of gain on the line input to your
sound card Chris? The processor on the radio would only normally be
working on mic in of course, so things are likely to sound different
anyway.
Perhaps you should try processing the audio BEFORE it goes on the AC97
card ?
Have a look at this site
