Hello

yes I think there're still some rounding errors or things like in ste 
dma sound code. I'm trying to improve the precision for others bad 
quality in some demos, so this will certainly benefit to this program too.

By the way, could you test on a real STE the program DMA_TEST that Paulo 
posted on http://atari-forum.com/viewtopic.php?f=28&t=20760&start=25 ?
The value slightly change on each run, but I'd like to know what you get 
on a PAL STE.
