So $100 for a box that gives audio out you can't use as is and you can't
split without opening the box and hoping that there is a way to get at the
digital part of things before they get to the DAC. Then a small fast
computer or custom hardware to split this into 16 channels followed by 8
stereo DACs for less than $1k. You are only making one or a few, so your
time designing the thing is signifcant, as is the time to design the
software to mangle the audio signal going to the device to hold 8 channels
in one. Then you have the time required to modify the original box as well
as add your mod to it. If you can assume less than $400 for parts, that
only leaves you with less than 20 hours to design, test and execute at $25
an hour... which is pretty poor pay for engineering work.
If there was nothing available, that would be ok, I guess. However, I
think with what is available, the job could be done for less when hours is
included (and I am not at all sure that $400 of parts is realistic at one
off prices)
Of course the other question is, what digital monkeying is happening
inside the chips they use. That is, is the digital part transparent?
