Is better asndlib o aesndlib for this stuff?

First you have to obtain a 8 bits signed RAW PCM sample. You can use for example audacity.
After that you have to link it to your program. You can use raw2c.exe utility to do that.
copy and include include the files generated.
use ASND_Init() to initialize th library and ASND_Pause(0) to let play.
Finally use ASND_setvoice to play the buffer.
