GPL: DirectX 7.0a sound issues

by Jari Jokine » Sat, 08 Apr 2000 04:00:00

Does anyone else get worse sound quality - less treble (propably due to
lower sample rate), "scratchy" sound and more pitch quantization - in GPL
with DirectX 7.0a? The difference to DirectX 6.1 is easy to hear when using
engine sounds with lots of treble.

The problem isn't always present: After viewing a replay it is sometimes
possible to get normal sound, but as soon as the engine rpm goes below
certain limit, GPL (or DirectX 7.0a) switches back to low quality sound.

I have a Diamond MX300 (Diamond's own drivers or latest refence drivers by
Aureal) and Win98. Previously I have stayed with DirectX 6.1, but since it
was disk formatting time anyway, I gave DirectX 7.0a another try. Thanks for
any help.

I get scratchy sound sometimes, am running 7a but really thought it was more
because I was running the SB Live card. If I knock down the sound volume in
windows slightly, it seems to go away.

Doesn't help in my case:( My ears tell me that GPL just swithces to lower
sample rate (not lower pitch) and uses rougher pitch quantization with
DX7.0a.
