ESP8266Audio VS arduino-audio-tools

Having an issue here using the ESP8266 Audio library (found here).

The Arduino sketch that works for me reads the data out of PROGMEM. When I use that same raw data in ESPhome, it crashes my ESP too. Would there be a way to play from PROGMEM in ESPhome too? Other ways in the library are a function or streaming, but that doesn't fit my use case unfortunately.

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.

Not sure where you got that. According to the ESP8266Audio documentation, the default GPIOs are 2, 15, and 3. You're trying to change 15 to 13.

ESP8266Audio is really fun and easy to use

The ESP32 might suffice for that then, depending on what you consider to be basic applications. It certainly has wifi and bluetooth functionality and you can do audio with an extra chip or an interesting workaround. The ESP32-A1S module even has the necessary chip integrated but you'll likely need to roll a custom PCB for it.

I am simply using the sample code from here. https://github.com/earlephilhower/ESP8266Audio

Have you found Phil's audio tools for Arduino, they work great on ESP32. https://github.com/pschatzmann/arduino-audio-tools

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 :

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.

The ESP32-A1S is a fun toy to program with that lib https://github.com/pschatzmann/arduino-audio-tools on that cheap kit: https://docs.ai-thinker.com/en/esp32-audio-kit

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.

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.

Been wanting to do this myself a good source for this is this linkhttps://github.com/pschatzmann/arduino-audio-tools

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

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.

https://github.com/pschatzmann/arduino-audio-tools and you can program it with arduino
