No.02825 Tafoid Administrator Oct 13, 2008, 23:27	In the sound test, sample $33 in particular which says "Maggie!" - at least on my CPU, there is a noticeable distortion and roughness (crackles) to parts of the speech. Whether or not this is what the OP meant by bad sound - I can understand the observation based on this and other sound check samples. It's almost like the samples are being overdriven somehow..
No.02826 Smitdogg Senior Tester Oct 13, 2008, 23:41	That's actually a different "Maggie" sample than the one I heard in-game when testing... I hadn't checked the sound test until now. Guess it's still there.

No.07169 Fujix Administrator Jan 30, 2011, 16:05 edited on: Jan 31, 2011, 14:13	The wave form of the voice "Maggie!" shows that there is a short span wave values are shifted to bottom. It causes the broken noisy sounds. Looks like ~~higher~~ lower wave values cause the wrongly calculated and rounded span.
