title: How to analyze .wav and .dat file?
body: <p>I want to read .wav or .dat files and plot the spectrum, for the plot spectrum I need the center frequency and bits per samples, in the .dat file I can find the center frequency but I can not find it in .wav
  How can I calculate it?

  <p>I can also find bits per samples in the .wav file  according to the canonical wave file format but not in the .dat file, is .dat file contain it?

  <p>Is .dat file data stored in <strong>little endian</strong> like a .wav file?</p>
