the final solution:

i was thinking of opamp giving a difference between input and ref signals, but it still gives analog result...

Agemixer (04:55:44)
that would make wense and one RC circuit would do that thing pretty much, rising from 0v to 5v

Agemixer (04:54:14)
plus what if we leave the comparison for opamp or two for one (mono) signal instead of anything digital?

Agemixer (04:53:20)
but what if... 6526 timer? how? hmmz

Agemixer (04:52:41)
what if the input signal is approximated with multi-opamp chips? No.. too rough, gains only few bits and all that calibration and the component values.. still complex

Agemixer (04:50:36)
no.. still requires extra reads and writes per sample... then about a microcontroller... no way, too much of work perhaps, programming and all that

Agemixer (04:49:16)
i was thinking if a count-up/down chip would do as a faster counter versus c64's 6526 or CPU..

Agemixer (04:47:38)
because finding a correct sample value by sawtooth signal or forking with averaging the sample vs input line signal may bee too slow for code or for chips for efficiency like it could 44,1 kHz anyhow.. impossible as it is

Agemixer (04:45:04)
i was in imaginations.. hmmz hmmmz. I think i just invented more c64 friendly sampler, the idea
