Original code from [Zlo](https://github.com/flipperdevices/flipperzero-firmware/tree/zlo/wav-player) and most files provided by [RogueMaster](https://github.com/RogueMaster).
Create a wav_player folder in the root of your SD card. You'll need **8-bit, 2 channel, unsigned WAV files** (try [Audacity](https://www.audacityteam.org/) for conversion.)
