I've started to tinker with the samd21 chips...
This Arduino library for the Zero produces scratchy telephone quality playback. It sends 8bit sound to the 10bit DAC via this SD card library
Adafruit's circuit python actually sounds pretty decent playing 16bit audio from the same chip, QUAD SPI flash, to the 10bit DAC. hookup guide
Any ideas for porting a simple flash or SD audio player to Arduinoland? I have a couple flash memory chips ready to test but no library for DAC output with perhaps DMA support!?
teensy of course does it so well. I highly recommend teensy for powerful, inexpensive audio projects! I started to dig into PJRC's libraries to see if there was a way to port a simple player to SAMD21 and quickly got lost. Should I pursue that route?
