Hi, sorry for another one of these questions, but I'm wondering how to create an average frequency graph of a certain scene in Spectrum Lab. For example, I used the method on AVS (that was linked a few pages back) to create an uncompressed mono audio track from a movie, I then found the scene I wanted, cut it into its own ~30 second uncompressed wav track and put it into Spectrum Lab. Now I'm just wondering how I can get an average volume of the various frequencies for the clip. Thanks.
