Comment (by akantor):

 You are right - it comes down to a difference in the .wav files
 themselves.
 {{{
 $ file countToTwelve.wav
 countToTwelve.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM,
 16 bit, stereo 16000 Hz
 $ file sample.wav
 sample.wav: RIFF (little-endian) data, WAVE audio, stereo 16000 Hz
 }}}

 countToTwelve.wav is slow, sample.wav is fast.  So the problem isn't yet
 solved.

 It seems the difference is that sample has 32bit floats, and countToTwelve
 has 16bit shorts (which is way more common).
