It is hard to says something is workable or not if you don't know what the OP really wants or you suspect that he/she hasn't completely figured out what they need.

I can't know what he wants unless he declares it. So far, he has written

"I need to multiply a low frequency (human heart beat measured by a piezo crystal) of aprox one hertz by say 200, so that it would be audible. Realtime, with minimum delay. I wish to use it for biofeedback.
All its harmonics should be multiplied too."

Not translate, multiply. 1 Hz becomes 200, 50 Hz (there are sharp edges in the waveform) becomes 10 KHz, and so on. The resulting sound is to be continuous and in real time. I doubt that Devidas understands what that implies. It isn't just not knowing how to do it, it's not knowing what "it" is. I hoped to get him to think about that with my first message.

For some reason the OP hasn't posted any clarification.

Embarrassment at having posted a request for the impossible? Troll? It's not important to me. I'm done with this until he posts again. There's no gain from discussing how to accomplish what we suspect he might want.
