(digital line transitions = momentary stages causing erraneous, momentary high freqs)

Agemixer (03:04:06)
that kind of stuff.

Agemixer (03:03:38)
also a high freq filter cap could be needed for DAC (additionally), filtering the port digital transitions to the gnd.

... on how to read/write from DAC/ADC.

Agemixer (02:59:30)
at least less hassle machine-side sampler code, just perhaps. otherwise pretty much tye same idea

Agemixer (02:58:35)
but at that stage it is probably better to just buy a ready DAC or ADC chip that does most of that job automatically and.. less hassle and get cheaper perhaps

Agemixer (02:56:41)
and also schottkys at least to prevent line input or line outputs exceed or reverse peaks occur giving more than 5 v or less than 0 volts

Agemixer (02:55:17)
for tad more complexity, there could be a latch chip for inputs and outputs for digital signals buffered, but also some kind of output signal followers

Agemixer (02:53:06)
..to give it some line-level power, could be just be a simple bc547 transistor biased to center, and both input and output with a capacitor.

Agemixer (02:51:07)
always use capacitor in input and output lines of analog signal, you might also need a resistor (attenuator) for the final "line out" signal, could be resistor + trimmer/potentiometer of some lowish R value, so you might need a little preamp anyway
