You shouldn't need anything specific for Bluetooth LE audio in Espruino - you can just take the data and push it into a double-buffered
Waveformclass.Having said that, the data transfer rates sending on 'standard' Bluetooth LE are really quite low (2.5kBytes/sec) so you're not going to be looking at anything that's very good quality.
Hopefully at some point soon we'll add support for the increased MTU sizes which will give the data transfer rates a big boost, and then it'll get a lot more sensible.
