Just a quick note to confirm that the RP2350, unlike the RP2040, is able to decode full 44100Hz stereo MP3 files in real time.
I use David Reid's excellent dr_lib libraries https://github.com/mackron/dr_libs in MMBasic and there is no issue reading the mp3 from a FatFS SDcard or TinyFS Flash and decoding and playing it using PWM. This was one of the things that the STM32F4s could do that I simply couldn't find enough CPU cycles for on the RP2040 but the RP2350 eats it
