Currently it is limited to 16bit PCM wav files at 16 Khz. A bassier speaker would probably be nice as well.

At that point it would have the potential to actually be relaxing at night especially with some calmer thunder effects. Maybe more of a rolling thunder.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is my demo of Lab 3 for Georgia Tech&#8217;s ECE 4180 Embedded Design Course with Professor Hamblen.
