Sample rate: such 8000, 11025, 16000, 22050, 44100 Hz or 48000 Hz. Bits per sample: 16 bits (audio sample data values are in the range [0-1024]) Number of channels: 2 (stereo) The wave from the USB Key is parsed to detect the sample rate in order to configure the I2S accordingly. When the play back begins the blue LED starts toggling.
