Just Released My ESP32-S3 Audio Dev Board
If you're getting started, the ESP8266Audio library makes it easy to play audio with the Arduino toolchain. For more advanced use cases, Espressif's own ESP-ADF has a lot of useful features and examples.

LyraT onboard microphones
Take a look at the ESP-ADF recording example. https://github.com/espressif/esp-adf/tree/master/examples/recorder/pipeline_recording_to_sdcard

Ugh.. ADF
Sorry to break it to you, but the Korvo-2 is an ESP32-S3 based board and does not have classic Bluetooth (only Bluetooth LE). The a2dp+hfp example only works on the original ESP32 boards. See this table: https://github.com/espressif/esp-adf/tree/master/examples

ESP32 Audio ADC libraries
I'm mainly looking for a direction toward a library that may assist in my project, or whether I need to do all this from scratch. Is esp-adf (https://github.com/espressif/esp-adf) something I should be looking at, is it relevant to the parts I'm using?
- Sending Analog Audio as Voicememo or call.

New to Arduino - Controlling iOS device (ipad, iphone) with remote
Example code https://github.com/espressif/esp-adf/tree/master/examples/player/pipeline_a2dp_sink_stream this is technically making a headphone with remote control but you can still use it as a starting point.
- Creating an 8-channel, 16-bit audio recorder with ESP32 -- possible?
- ESP32-LyraT webradio / mp3 player with web interface
-
esp8266 as an intercom and connect to my asterisk server
Espressif has an example for the esp32. I’m sure you could use it as a starting point to build what you need.

Sound Module Suggestion
This library documentation has some more information on this... https://github.com/schreibfaul1/ESP32-audioI2S/wiki
- Trying to figure out how to play an audio file using a ESP32, this is our build, code in the comments. Any assistance?

Butting my head against extracting ID3 data and putting it into a JSON/Updating a Web Page
I'm using Audio.h, and have reverse engineered the library: https://github.com/schreibfaul1/ESP32-audioI2S/blob/master/src/Audio.cpp

- Thoughts/ Point in the right direction?

Combine 2 analog signals = mixing?
Are you sure? This project seems to think otherwise, although if you want analog it might be a fun experiment to make it use the ESP32's DAC rather than the I2S peripheral.
-
Is it possible to stream audio from a web server to an ESP32?
I think the best way is to use a I2S amplifier, and a library like this: https://github.com/schreibfaul1/ESP32-audioI2S

HELP! Cannot get I2S output on Adafruit esp32 feather V2!
I use that same DAC for this project : https://github.com/marchingband/campusradioradio/blob/main/campusradioradio.ino which uses this Arduino library https://github.com/schreibfaul1/ESP32-audioI2S

PSRAM alternatives?
I need to add more memory to my Lolin32 Webradio to avoid the constant dropouts that some stations have given. I use the ESP32-audioI2S library. Here in Brazil, access to components is extremely difficult, and we often resort to expensive imports via Aliexpress or eBay. The modules or memory chips that we have on the market are usually of the I2C flash type, like this one or this one. On Aliexpress, the only PSRAM I found was the 23LC1024 chip (128kB - $5.04). But I see chips 23K256 (32kB SPI serial SRAM - $1.38), 24C1024 (128kB I2C EEPROM - $2.30) and 25LC1024 (128kB SPI EEPROM - $1.84) available. Can I use these cheaper options?
What are some alternatives?
