Is it possible to capture good sound with Aduino? I need to record street / birds / nature sounds.
As I found, maximal sample rate, achievable with built-in ADC is 9kHz, which is to low.
So, I require to use some external hardware. But wave shields I saw are to expensive (comparable by price with Arduino itself), probably, because of excess functions (including not only ADC but also DAC and so on).
Simultaneously, there are ICs, providing ADC functionality and even MP3 encoding functionality for relatively low price. But here a schematic design required.
So, how to find appropriate solution here?
