E-prime sound creation

[Matthew Conroy]

I'm trying to use tones of different frequencies as auditory stimuli. As far
as I can tell, E-prime requires pre-made wav files and cannot generate tones
on its own. Does anyone have suggestions for creating wav files like this or
a place to get them? In addition to the tone's frequency and duration, I'd
like to have control over the ramp up/down time as well.

Many thanks,
Matt
