Paranoid is correct, you can do volume changes without mixing the internal pulse. So it's 100% software generated. Some sample players do that, some set the internal period to 0.
The two examples I wrote are 1) 4-bit sample with max 15 volume levels 2) 8-bit sample with volume setting to each channel. By converting the sample data to this code will run at the speeds I mention. No interrupts or anything, just a massive list of code.
But it's all useless with these high rates and/or large code it generates. However, I can't think of a faster way to do that (now waiting for tIn to arrive with a completely different idea that is much quicker :).

What's the anti-troll code? That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
