Microphone audio input to hdmi output

[freshoutdakitch]

Hello, first post here. I am also fairly new to raspberry pi

I have small microphone board found here: https://www.adafruit.com/product/1713
I want to take the audio signal from this microphone as an input and output the signal through hdmi.
The goal of my project is use this along with the V2 pi cam to create a nice DIY webcam.

Is this possible using this microphone board?
Any other advice is appreciated.

*I'm using the rpi 4B 4GB RAM model

Thanks in advance!

That microphone board has an analogue output. No model of RPi has an analogue input. You would need an audio Analogue to Digital converter between that board and a RPi. A USB sound card (dongle) with audio input contains such an ADC.

Not just an ADC, you actually need a CODEXCODEC, (coder-decoder) an ADC is not designed to sample sound, just analog signals.
Two choices, an I2S (inter IC Sound) CODEC, or an USB sound card

1. I did write "audio Analogue to Digital converter". How is that "not designed to sample sound"?

2. The word is "codec", standing for "coder-decoder", not CODEX which is something completely different. https://en.wikipedia.org/wiki/Codex

Perhaps the OP should instead have purchased https://www.adafruit.com/product/3421

Thanks everyone for responding.

drgeoff, I think you're absolutely right about https://www.adafruit.com/product/3421
That looks like the one I need. Guess I'll have to shelve my analog board for a future project.

A simple USB microphone won't work?

Well with usb microphones, I can only find either bulky expensive ones, or small ones like this:

I need it to be small, but these kinds ^^ seem to be junk based on reviews.
Also, using something like an adafruit board is a bit more hands on, which is also something I like about it

I've got two of those little ones and they work fine for my intercom. You think the Adafruit card is going to give better audio?
