I'm trying to create a prototype using a breadboard that is able to record sounds at the ultrasonic frequency range. I am looking into purchasing this microphone.
The problem is that the Raspberry Pi only has digital inputs. I researched and found this ADC. However, from speaking with the guys who run this company, they basically said that this would not be able to handle audio and is only used for simple analogue signals.
Does anyone have any ideas to where I can find a ADC that would suit my needs?
