Is there a way to tweak audio quality on a PHAT BEAT?


Picked up a Pirate Radio off Adafruit. Cute design, fun quick build, but audio quality is a bit fuzzy/crackly. I know without a box on the speaker it’ll always be a little bit thin but if I theres some settings I can tweak to clean it up I’d like to. Im using sharepoint-sync for airplay. As a side note, is there a BT module I can use in place of sharepoint-sync? I’d like to use this at work and won’t be allowed to put it on the WiFi.
