[A83] Re: Need for speed




For outputting 8bit samples, you 'll need to use PCM to convert them to 1
bit...
this means you 'll need to output 256 bits for every wave. 4.77 mhz / 256 is
almost 1.65 clockticks per write to the speaker... i don't think you can
write a player wich is fast enough...

since you are already converting/compressing the wave, i suggest you convert
it to 6 or 7 bit samples...
