Read WAV file from SD convert to I2S with 48kHz Sample Rate

was looking at the teensy 4.1 but it can only do a 44.1kHz sample rate without major modification to the audio library

If you can’t do it with the Teensy 4.1 then you won’t do it with any processor, it is by far the fastest board around by several orders of magnitude.
