Yeah, he has a copy of it.  As do I, but I'm not too comfortable sharing it, seeing as it was never released.

You may need to ask him permission then, first, in case.

I really do want to add wav support eventually.  I'm really not that knowledgeable with sound though, so I'd either have to learn how waveforms of sound are converted to digital audio or I'd have to have someone explain it to me.

This was done on a z80 cpu by the way with the most minimal of sound chip:


This and the ProjectM sound (from what I've heard) make be believe that it will eventually be possible.  When I support reading from archive, you'll be able to play some pretty large files.

Cool! I like the video...
Yeah, without support for external drives, an SE (83+SE or 84+SE) could hold one low-quality song...

this is nice. My concern about Axe sound is efficiently do multiple channels at once. I tried alternating very quickly once, but the sound got really weird. Could it have been because I was using an emulator?

I tried the same thing on calc (alternating between two sounds [3 also]) and it didn't sound wierd, sounded almost like normal, just different pitches.  My guess is yes, it was the emulator doing it.  I think my code was something similar to:
Code: [Select]
100->A->B
repeat getkey(15)
sinreg(A,1000
if getkey(54)
sinreg(B,1000
end
if A!=255 and getkey(3)
A+1->A
End
if A!=0 and getkey(2)
A-1->A
End
if B!=255 and getkey(1)
B+1->B
End
if B!=0 and getkey(4)
B-1->B
End
end
this code should work, I haven't tested it however, but it is pretty close to what I used for testing multiple channels.

I'm going to write a library to allow users to play sound in their games.  It will come with a designer to make music.  Should be fun.
I was messing around last knight to make sound in different pitches and made a C Major scale pretty easy.

I see what you did thar...

Yeah, the only issue with sound it seems is that you can't play a pitch for longer than ~65k microseconds

You can make it longer if you loop it.

So I figure I will make a library that will let you use 6MHz for your game, and it would use 7 for music.  Ideas?
I also recently started work on a music editing program for Axe as an application.
