@Dant2142 I recorded the vic chip demo from my real C64: just watch video ZW2XKSWUPLw (put it behind /watch?v= in the url bar or search for "vicious sid vic")
Well, MOS6581 is basically an analog synthesizer chip which you control directly with assembler or software to create audio. Samples are just recorded audio. It is like comparing a synthesizer with a recording of a sound made with the same synthesizer and saying they are not the same. :)
In this demo, they are actually playing digitised audio (a sample) trough SID.
But it is not important. I meant one of the "instruments" in the track had the same kind of feel as SOTB or DoW on Amy.
@jci10 16-bit digital audio requires a 16-bit volume control, and the SID's volume control is only 4-bits. so the answer to your question would be... NO!
@Atad64 Yeah, but the frequency registers are 16-bit and there are three of them. I guess you are saying that the difference between two frequencies, say, $A400 and $A401 into 54272/54273 essentially create the same voltage to the speakers?
@jci10 I meant that despite of having 16bit registers, resolution of (for example) sawtooth wave is 12bit. So using SounDeamon`s technique cant give You more.
PWM is nice, but if i don`t err there is a 4KHz limitation due to max SID oscillator frequency... and this ugly carrier noise...
OMG.. 0:55 sounds very simmilar to Amiga..
Love u C64 forever.. Cheers from Poland !

Aww, the Vic chip demo didn't pickup. Great upload anyway though.

MDG is back... this stuff is amazing! Incredible what people invent and squeeze out of the sixty-four! ... C64 for life!

Very nice work. I like it. One of the samples reminds me of the amiga game "Dogs of War" or "Shadow of the Beast" :D
But anyway. I still have a working C64 here, I just need to build that XA1541 cable... TO be able to enjoy the good times. :)

In fact the C64 does not use samples.The Amiga does.

Nice job! Query: Shouldn't 16-bit with filtering sound be possible with C64's 16-bit frequency registers? More a of FM modulation of the sound?

@jci10 Frequency registers may give you 12 bit digi playback max.

What about the 12-bit pulse width waveforms?

Yes! VICE 2.1 with FFMpeg libs.
Part 2 is a bit Wonky. Seems like conversion from 50FPS to YouTube .flv format fails.

Was it recorded on the new VICE 2.1?
