Resample MHz signal

Please excuse me for starting another thread on this topic. My
apologies for not being specific enough the first time. But I did
learn something.

What I am really looking for is external hardware that will allow me
to upload an audio frequency WAV file, such a voice or music, from a
PC and then play it back at 100 times the original sample rate.

The program I am using is CoolEdit, which has a built in tone
generator with modulation and eveloping. It can produce 8, 16 or 32
bit resolution at 12 discrete sample rates between 6000 and 192,000.

The idea is to take advantage of this program's functionality and
user-friendly GUI to produce complex signals above the audio range.

PC software (alone) is not a solution as the resulting bandwidth would
be 2KH-2MHz, and therefore beyond the capablities of a standard
soundcard. DSP-based boxes for musicians are equally unsuitable for
the same reason.

I seem to need a lab-type device, or something I can modify or build
from scratch. Do I have any viable options here?

I have Googled big time and so far found nothing. Signal transposers
would be a great project for an electronics magazine. Think of all the
applications.

I hope my aim is clear enough to attract an expert response.
