I need to reproduce a certain sound wave form, specifically, the sound
of a heartbeat, and I need to do it with only a few dozen bytes of ram,
on a PIC MCU. The sample itself is 250ms long, and I have it in
uncompressed audio format at 11khz, 8 bits, mono. Is there a way to
create a mathematical algorithm to generate the sound on the PIC?
Otherwise I would need 344 bytes of ram, and thats more than the PIC
has total not including the ram needed for code and all the other stuff
I am doing on it. The heartbeat must be exacly reproduced, so I cant
just generate an approximation.
