[grc] Sound Quality Issues

[David Klann]

Greetings Fellow Radio Geniuses!

We're running into an audio quality issue here at WDRT 91.9fm in rural
Western Wisconsin. I'm past the point of tearing my hair out in search
of the root cause. I'll outline what I can here, and answer further
questions as they come in. Thanks in advance for your thoughts and help
diagnosing this.

Some facts:

 - The quality of *some* (not all) spoken-word audio recorded in our
"Studio B" sounds like it was recorded with the person speaking through
"a metal pipe while in a tunnel" (that's the best description we've been
able to come up with)

 - It *sometimes* depends on the radio people are listening to when it
happens

 - Music recorded in the same studio from any source (analog vinyl, CD,
digital source, etc) sounds just fine

 - One listener has noticed that it sounds "bad" when they listen with
their home receiver set to "mono" mode, and when they switch to "stereo"
mode it sounds fine

 - The same audio sent to our Internet stream *usually* sounds "normal",
but sometimes sounds "bad"

This has been an otherwise productive exercise for us because we've
learned of a few other misconfigurations in our audio chain. But this
one continues to haunt.

Again, I appreciate any thoughts you can share, and will provide more
info as requested. If off list, I'll summarize the "fix" to the list
when we figure this out.

Thanks!
