oops i meant 44,1 kHz

Agemixer (05:15:08)
with speedcode, no loop

Agemixer (05:14:40)
this read+store sample would take 24 cycles at least, a 44,1 kHz rate needs 22,3 clock cycles at max. involving an Y-register trick we just achieve 22 kHz!

Agemixer (05:08:21)
now it only needs a "start sampling" line, one write and ldx CIA_counter , lda real_sample_LUT,x

Agemixer (05:05:02)
Then the curved sample can be read from CIA counter register (delay of cycles), and linearized by this reading the real sample amplituee from lookup table once. Voila'

Agemixer (05:03:00)
the reach signal is given back to c64 userport line which tells the CIA counter to just stop counting (1MHz resolution)

Agemixer (05:01:40)
RC circuit reference signal (resetable), and line input just to opamp input.. gives out a logarithmic curve delay before the result gives "reached"

Agemixer (04:57:55)
the final solution:

Agemixer (04:57:24)
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
