[sdiy] dsPICs with DACs: linearizing the 12 bit ADCs, external RAM?

For single instrument inputs, if the instrument is going to undergo
heavy processing, this doesn't matter that much, really. Each of those
instruments would probably be at -12 to -20 dB in the mix which lowers
their effective output to those 13-14 bits (and most possibly 10-12
bits effectively because of the DAC crappiness). The effects obscure
the sound even more, so shave a bit or a couple off that as well.

If the ADC does high frequency sampling, just average out pairs of
following samples to half the output rate and add a bit of input.
