The only sound argument I have found for using integer fixed point over
float can be summed up in two words:
Denormal Number
Although deft coding can alleviate it somewhat, I can only hope that
with the Itanium, Opteron or whatever, this is no longer a problem!

They actually make *more* sence as an audio
format, since there, it
can have a real effect on performance. That's only really relevant
for old or low end hardware, though. (That's why Audiality does it -
but only in the real time synth. I'm simply not motivated enough to
implement the off-line oscillators in fixed point... *heh*)
Right, but on current (PIV and AthlonXP) float is slightly faster, and
significantly so on the next generation Intel chips.
