Would it be possible to hook up 32 Audio ADC/DAC to one Gumstix. I want to be able to read 32 channels of uncompressed mono audio (16/44100) using the gumstix. I know that there are 42 GPIO pins accessible, which doesn't leave much in the way of interfacing with that many components. Is there some sort of latch/buffer that could be integrated between the adc/dacs and the gumstix to allow reading batches of data (say 4 or 8 adc/dacs to one interface on the gumstix)?
