title: Dynamic time warping to compare two audio recordings
body: <p>I'd like to use Dynamic Time Warping to compare two feature vectors for two audio recordings (of course I'm doing all the necessary preprocessing first). My program should output the similarity between the two audio recordings in percent. For example 100% means that the two recordings are completely identical, and the more different are the recordings, the lower number I get. How do I get around to it? The DTW only gives me the length of the path or the cost of the transition and I don't know how to convert one of these numbers to a percent value.</p>
