When playing 16 channel mods I was not implying actually using a 16 channel device. Mixing the sound into four channels will do quite nicely - add a volume boost feature and bob's your uncle (thank god he's not!). When outputting to say the SAMdac you would end up with 5 bits for each channel since it's got two 8 bit outputs = four 7 bit outputs = eight 6 bit outputs = five 5 bit outputs. Because you are mixing 16 five bit samples together they still sound amazing. The extra processing power would therefore be used for mixing and not for outputting. 16 channels is four times the amount of 4 channels therefore with a sam running at four times the speed I can output a 16 channel mod at 10.4khz (as the current mod player does). Some extra power would be used to beef the sample speed up to 15.6khz, and even more could bring it up to 31.2khz - the problem then being that half of your line interrupt time is being used to pause for the second sample output on a line. Anyway, enough on the mod stuff (has everybody bought a copy of the SAM MOD player version 2.02 yet by the way???? Only five pounds. Just needed to put that small plug in there :) since I was rambling away about mods) With the Quazar you would finally have a good use for 16 bit mode since even with mixing the quality would be excellent. BTW does anybody know if Craig Turberfield has still got an e-mail address. I checked out his WWW homepage and mailed to the address included but got my message thrown back in my face.
