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?

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?

Play file by name Esp32 I2S
Boards like the Adafruit Audio FX Mini, DFPlayer Mini, JQ6500 etc. all have the ability to call files by name/number. The TMRh20 library uses something like tmrpcm.play((char*)"EST_FART.WAV"); but isn't compatible with the ESP32. There is, however, a spin-off version AutoAnalogAudio, based on the TMRh20 library for the ESP32, but as far as I can tell it is for DAC. It does, however, use playAudio("/SHEEK_RATTLER.wav"); to call a file by name using myWAV.h.
What are some alternatives?
When comparing ESP32-audioI2S and AutoAnalogAudio you can also consider the following projects:
ESP8266Audio - Arduino library to play MOD, WAV, FLAC, MIDI, RTTTL, MP3, and AAC files on I2S DACs or with a software emulated delta-sigma DAC on the ESP8266 and ESP32
arduino-audio-tools - Arduino Audio Tools (a powerful Audio library not only for Arduino)
esp-adf - Espressif Audio Development Framework
yummyDSP - An Arduino audio DSP library for the Espressif ESP32 and probably other 32 bit machines
ESP32_WebRadio - An Internet web radio based to ESP32
freac - The fre:ac audio converter project
HubAlyzer - A spectrum analyzer display for HUB75 RGB LED panels and I2S microphones
Lolin32-radio - A Web Radio with Lolin32 Lite
