title: TV audio processing with TV capture card
body: <p>I'm looking for an open source library or framework to process audio signal from a TV capture card. The idea is to detect TV ad spots and register the time and the channel where them happends. I never worked in something like this, so, any information, link, idea is welcome.</p>
  
  <p>Thanks in advance!</p>
  
  <p>EDIT: I don't care about the language or the OS.
  I want to clarify that my objective is to detect the specifics ads of the company where I work. So, I think I should use the fingerprints of our ads and check them against the captured data. If you have information about this, is welcome too.</p>
