I've discovered a very odd problem. It appears to be very specific to
the Alison Krauss and Union Station Live 2 disc set.

This may get a bit long...

I have all my music ripped to my HD, of course, and I've been using
Inguz for a while. I use EAC and the FLAC (either 1.11a or 1.12, can't
remember right now) encoder/decoder that you get off the FLAC website.
Everything is all set up correctly, Plextor Premium drive is properly
configured in EAC (error correction methods, etc). Been doing CD
ripping for years.

With Inguz engaged I get a weird sound when I play track 5 on Disc 1 of
this set (Bright Sunny South), and a little of the same on Track 6. The
track starts okay, but within about 3-5 seconds it starts to sound
"warbly" and then actually sounds like it progessively is slowing down.
As the track continues it gets worse and worse. The first four tracks on
this disc sound just fine. To be honest I've been too worried to see
what happens if I let it go beyond about 20 seconds or so. This track,
BTW, and all others play just fine on my computer using Winamp (playing
the same exact file). There is also nothing wrong with the disc, as it
plays just fine through my transport.

Knowing that under these circumstances the track plays correctly, I
figured maybe I picked a too agressive filter in Inguz. I tried others
with no luck. I even set it to None with no luck. But when I went into
Slimserver and actually unchecked the FLAC->Inguz in File Types and
replayed the track it played just fine.

Now these tracks are recorded "hot". On EAC all the tracks on both
discs show they're ripped at 100%. And sure enough this track shows
clipping in the Inguz log file. So I figure what I'm hearing must be
clipping artifacts, although I couldn't figure how clipping could
actually make the music sound like it's slowing down.

So I take the next step and reduce the Gain in the Inguz config file.
Tried numbers down to -22dB with no success, and while doing this the
log file still showed clipping, but also still showed -16dB as the Gain
setting. I've got some possibilities now. Either:

1) The Gain setting is working, but the log file is wrong, and it has
no effect on my problem

2) The Gain setting is not working, and my problem is just a clipping
issue that lowering the Gain will fix

I followed all the instructions when adjusting the Gain: FF'd to a
different song, etc. I even went to a completely different album and
then went back to this one.

One of the things I'm wondering is whether my description of what I'm
hearing sounds like clipping, to those who have heard it themselves?
And, is there some trick to using the Gain setting that I might be
missing?
