Reply to comment by f10101 in [P] is it necessary to convert audio data from analog to digital? by SSC_08

Sounds good! Is this the same process for microprocessors and such (Raspberry Pi)?

Functionally, the process is the exact same as you would do on a computer, but for these, yes, you will need an ADC module. (as the Rpi doesn't have an audio-in built in).

For sanity's sake, I would recommend getting something like a USB audio interface, or a dedicated audio ADC module that contains all the audio stuff (rather than working with a generic ADC and trying to make it work for audio). Something like: https://thepihut.com/products/hifiberry-dac-adc might be a good option to start with, perhaps?

Sounds good! So just confirming, if I plan to use a raspberry pi, it would make sense to invest in an ADC module compatible with pi, correct?

Yes. Or I believe you can use a USB mic that is compatible with the pi.

Okay, so if I already have a USB mic compatible, I don't need the ADC converter?

Sorry for all the questions and thank you for your help!

Yes, exactly.

A USB mic is a normal mic that has a hidden built-in adc.

It sends you the digital signal over the USB cable.
