title: Generate .WAV sound frequency?
body: <p>Is there any script/tool out there (any language) that will generate .wav file into a waveform image?</p>
  
  <p>Basically I want to upload a small wav file on the web and it will then show an image of waveforms including numbers of seconds (duration). </p>
  
  <p>PS: I did google but no luck.</p>
