A13 + stereo audio input + Python

Hello all!

I bought an A13 a little while ago for prototyping a device I'm designing that uses ideally a stereo audio input. I realized by trying to acquire a stereo sound that the board only has a mono input!

Given that I'm using Python to code, what would be the best (easiest) hardware option for me? Again, I want to be able to record two sound waves @ 16 bits, 44.1 kHz, 2 independent channels.

Could either MOD-IO or MOD-IO2 boards do what I need?

Thanks!
Best,

There is no simple way to make stereo audio input on that boards. But you can try to use cheap USB soundcard.

I see... How about the MOD-IO and MOD-IO2 boards? Could they be used to that end?

I think, MOD-IOs aren't designed for that purpose. ADCs in ATmega16 can handle only 15ksamples/second at 10bits of resolution. The second problem is TWI - it isn't fast enough t to transfer that amount of data.
