HackerHotel2019 Badge Audio API
Enjoying audio is easy.
import audio
audio.volume(11)
audio.play_mp3_stream('https://badge.team/RoccoW_-_06_-_Pumped.mp3')
For streaming audio, a wifi connection is of-course needed.
Mixer ctl
Since the audio jack is reversed on the badges, and we don't want to force you to do a hardware modification, in software we "invert" channel 0 and add left and right to channel 1, this fixes the audio issue for passive headphones.
NB: This is automatically done by the firmware after the day 0 OTA. You can chose to disable this mod or use the mixer_ctl api for other effects like balance between left and right, or swapping channels.
