I've used lab view on Macs but not on PC's. Call Labview, they know who
has developed what you need. I do speech perception work on a PC and
use Turtle Beach sound card with their native application - Wave.
Pretty inexpensive. I also have Sonic Forge. Very nice but much more
expensive. Generally, if you need simple stimuli - like a sine wave,
you can generate it off line (say from an audiometer to a tape deck),
then import it through the sound card and the software, then save it.
If you're really serious about using a PC, use a very fast processor
(100 MHz or faster), and a hard drive designed for audio-video work.
You want the fastest transfer rate possible it you digitize at high
rates. You also need a large disk drive - audio files take a lot of
