Re: [OT]Hardware Speech Systhesis

Actually the sound difference between sampling rates depends heavily on the
chipset used and how the audio path is dealt with.  I have an old turtle
beach sound card that still blows away anything that I have heard and the
DSP on the card makes 8 bit samples sound pretty darn good. getting rid of
the digital artifacts in the audio is a big key. CD quality is really only
16 bits, and unless you have really good speakers the higher harmonics
picked up by the higher sample rates and higher bit resolution are hard to
hear. (Although this will go with  the flame wars on that bi-wire is better
than single runs, flat wire, ribbon cables, monster wire, solid conductor
versus stranded, etc... ) Unless you can take a bunch of different cards
and play with them on the exact same system with the exact same listening
location there is no way to really tell which is really better, and I have
found that a illegal trick that used to be used in Home and car audio - the
distortion box, is starting to be used in computer audio. :-/ those
displays that have the neat buttons to select which speakers to listen to
just may have a distortion box hidden inside.

as for 8 bit's versus 16 on voice synth...  do 16, it's easier on your
head. but 8 will work fine.
