Has anyone figured out a way to record multiple songs from the audio input of the PJRC Audio Shield board and save them as wav files to the SD card for later playback? This would require auto assigning a new name to each file. I'm not sure this is possible without DOS software creating a file structure on the SD card and something the sgtl5000 chip can do on it's own. In any case, it would be nice if recording on the SD card could be done from an audio input line from a computer, CD/DVD player or cell phone. Any thoughts?
