title: How to decode a Binary Signal in a Wav file into Binary
body: <p>I'm doing a puzzle that gets me to call a phone number which produces a load of
  beeping sounds. Putting this into audacity as a spectrogram produces this: <a href="https://i.stack.imgur.com/YTebn.jpg" rel="nofollow noreferrer">image</a></p>
  <p>Zoomed in it looks like this: <a href="https://i.stack.imgur.com/sfL8p.jpg" rel="nofollow noreferrer">image2</a></p>
  <p>This looks like On Off Keying. The problem is i don't know how to take this binary signal and convert it into actual binary (other than doing it by hand but yikes). So far GNU radio seems to be promising but I'm not tooooo sure on how to achieve what I'm looking for with it.</p>
  <p>Thanks.</p>

  <p>The overall recording is also low quality - the original is taken from calling a phone number which transmits this sound - getting a high quality recording of that call would also prove helpful.</p>
