Hello there,
I am trying to make a system with teensy 3.2 that be capable to acquire sound between 20 Hz - 20KHz
and make the FFT analysis to send to my computer via wifi.
I bought a microphone electret and i think, i'll buy a chip to amplify the signal and connect it to ADC teensy for make FFT Analysis.
Do you guys know about some chip that can make this work?? i thought about max9814 but i don't know is compatible with the teensy 3.2.
The other question is about ADC included in teensy. This ADC with 8 bits, it is suficient to make a FFT analysis ?
I notice about audio teensy shield but isn't what i need, because i only need input system.
