Pokey 5 1/2 bit volume only samples?

[Sheddy]

I was researching and coding up some sample playing routines a while back on 8-bit, and I came across some info about a demo, or digi player(?) (from Kactus & Mahonney, I think), that claimed to be 5 1/2 bit resolution. Any of you pros know how that might work, or is it just a joke?

 

Only ways I could think to get more than 4-bit would be a "dithered" sample rapidly changing from, say 2 to 3 to give the effect of volume 2 1/2?

 

Or can the channels be "combined" in volume only too? The manuals warn to not exceed 32 volume when using more than one sound channel. Can volume only give greater speaker excursion with more than one channel combined? If so, the emulators don't seem to allow for this. My experiments didn't seem to work with this. (Although it could be trying to convert the sample data that was the problem)

 

Not desperate for an answer, but curious if anyone else has tried this kind of stuff!

Dunno...maybe they were referring to octives...LOL.

 

'Course my Vic20 SuperExpander claimed to provide 1024x1024 screen resolution in it's ads. (ROTFLMFAO)

(shock) I have never heard demo writers exaggerate before.

 

(got to try all the graemlins)

i read something similar in some c=hacking issue.... i can recommend c=hacking for everyone interesting in 8bit coding...

just browsed through issue #21 from feb 2002 and found dissassemblings of several "minigames"... there was a contest:

You are right Heaven,

 

so it is possible.

there it is in issue 11 c=hacking. code and explanation too. Lots of other stuff too. I'm adding this link to my favorites (even though it's C64!)

 

Thanks
