[vorbis] applaud.wav sounds worse in 1.0?

Surely better trained than mine, then. :^)

I can't do that. applaud.wav was one of the very few samples where I could 
recognize artifacts in RC3; they were still barely noticeable at -q 4.99, 
but went away at -q 5.

On 1.0 I have a hard time hearing that noise at -q 2!

Now the only sample that needs -q 3 to be transparent is fatboy.wav (at the 
same location). Well, apart from that pesky udial.wav that's as broken as 
before. ;^)

So, I've changed my chosen encoding level, from -q 4.99 to -q 3, the 
default, for a gain of 20-30% in size, and I'm confident I won't regret this 
decision.

Vorbis is a-m-a-z-i-n-g! Thanks again, Monty and crew!
