Notes:
Currently only 16-bit linear PCM audio is supported for .wav files. The sampling rate should be
automatically detected and the audio will automatically be down sampled to 8kHz. Stereo channels
are also detected and mixed to produce mono output.
.pcm files should be pre-formatted to 16-bit 8kHz mono format.

same location as ringtone tool.
