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

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?

Need to send an I2S audio stream from an MEMS Microphone to Mobile app using ESP32 Bluetooth Realtime. Need some advice!
Have you found Phil's audio tools for Arduino, they work great on ESP32. https://github.com/pschatzmann/arduino-audio-tools

A Low Latency Guitar Effects Processor Suitable for Running on a Raspberry Pi
I use an ESP32-A1S board for that. I use this project https://github.com/pschatzmann/arduino-audio-tools/ and the platformIO vscode plugins.
Have a look at this example to see how easy using that library is :

Audio and Arduino
Check out arduino-audio-tools and other libraries it can make use of, such as ESP32-A2DP. It's tailored towards ESP32 devices, but also supports the RP2040 and others.

Looking for way to modulate MP3 file with 40khz
I have already successfully generated a fairly good 40khz sine wave with the internal DAC using this library: https://github.com/pschatzmann/arduino-audio-tools. I have also played an uploaded MP3 file, but I cannot figure out how to implement FM specifically to modulate the two waves together.
-
PWM or DAC for audio output using RP2040 as the MCU?
The PCM5102A does a great job. You can get modules for a few dollars, and can even get hat specifically designed for the RP2040. I've got one to work with an ESP32 with the Arduino Audio Tools library. Andreas Spiess has a great video on the subject.

Normally I’d recommend one of my YouTube videos :) - but actually this guy has done an amazing job: https://github.com/pschatzmann/arduino-audio-tools

Play file by name Esp32 I2S
I got it to play both MP3 and WAV files using ESP-audioI2S and arduino-audio-tools, though only single files. AAT uses player.copy() and the other uses audio.loop(), both can call files by name but only once, as far as I can tell.
