Stereo samples are stored LRLRLRLR where L and R are 8-bits each. To play back a mono sample you could try...
set DMA to STEREO mode
A0=Mono Sample Data
A1=DMA buffer
D7=bufferlength in words-1
fillbuffer_loop_LEFT
move.b (a0)+,(a1)+
clr.b (a1)+
dbra d7,fillbuffer_loop_LEFT
this would play from the left channel
whereas...
fillbuffer_loop_RIGHT
clr.b (a1)+
move.b (a0)+,(a1)+
dbra d7,fillbuffer_loop_RIGHT
this would output to the right channel

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
