Hi Folks!
Shame on me - ok. I really have no idea how to play an 8bit digisound sample on the PSG. All i found on the net is to combine all 3 PSG channels to reach a better sound than 4bit digisound on 1 channel. (Because the Volume Register of any channel is 4bit)
Well, i just want to understand the basics to be able to play digisound. I know already, that a digisound is definded by its resolution in bits and the replay rate in KHz. That's clear so far. But i don't know how to interprete the values of a digisound value - means: on a 8bit sample there are values like 0 (zero) that means silence - but there are positive and negative values up to 128 - ok, a greater value is a greater sound, but what is the difference between negative and positive values ?!??
If anybody knows - how to setup the PSG - and like to share this information -- please, help me.
