    Sampling ultrasonic signals

    Hi, I want to sample 4 audio sources which frequencies would be between 30 kHz and 40kHz (ultrasonic signals). Is there a microcontroller with ADC that could do that?

    Advice for ultrasonic signal processing.

    Hi everybody! I need to recover the signal captured by 3 or 4 hydrophones and doing the respective signal processing (amplification, filtering, ADC). What kind of microcontroller should I use in order to do that? The recovered signal should be between 25 kHz and 200 kHz. Thanks!
