title: Programming Wavelets for Audio Identification
body: <p>How exactly is a wavelet used digitally?</p>
  
  <p>Wikipedia states</p>
  
  <blockquote>
    <p>"a wavelet could be created to have a frequency of Middle C and a
    short duration of roughly a 32nd note"</p>
  </blockquote>
  
  <p>Would this be a data structure holding e.g {sampleNumber, frequency} pairs?</p>
  
  <p>If a wavelet is an array of these pairs, how is it applied to the audio data?</p>
  
  <p>How does this wavelet apply to the analysis when using an FFT?</p>
  
  <p>What is actually being compared to identify the signal?</p>
