bee bap boo bap bap, we're testing out our I2S BFF that we designed a few months ago (https://blog.adafruit.com/2023/01/28/a-new-bff-with-i2s-audio-amplifier/) - makes adding high quality audio really easy for many microcontroller boards like the RP2040 or ESP32 QT Py's. Here I'm running an MP3 streaming demo (https://github.com/schreibfaul1/ESP32-audioI2S) on an ESP32 QT Py and it's working great to play Frequency by BartleBeats direct from Bandcamp (https://bartlebeats.bandcamp.com/album/frequency)! Of course it also works great with playing from onboard flash or micro SD cards, particularly in CircuitPython where we have concurrent I2S audio playback baked in.
