Detailed Description

template<typename AudioFs = SdFat32, typename AudioFile = File32>
class audio_tools::AudioSourceSDFAT< AudioFs, AudioFile >

AudioSource for AudioPlayer using an SD card as data source. This class is based on the Arduino SD implementation Connect the SD card. For UTF8 Support change SdFatConfig.h define USE_UTF8_LONG_NAMES 1.

Note: Supported only by Arduino platforms that support SDFAT library!; Dependency: https://github.com/greiman/sdfat
