Converting Analog to Digital audio

by geoff2802 on Fri Jul 23, 2021 12:26 am

Hi all,

I'm intending to put together a stereo analog to digital converter. I could just buy one but it would be more fun to create one. Requirements:
Inputs: 2 line level audio signals (max. 2 volts). Two conductor from RCA jacks on source component.
Output: SPDIF.
Resolution: 16 bits.
Sampling frequency: 44 kHz.
I use Arduino IDE.

Is this Adafruit Huzzah32 ESP32 capable of meeting these requirements?

If this is achievable, how would I output the signal to SPDIF?

If it's not sensible to use the ESP32 board for this purpose, what would be a good choice? A Teensy perhaps?

All input is appreciated!

Cheers,
Geoff.
