So we decided to build a tool that did that for you -- or at least get you there most of the way! Our initial implementation is somewhat naive and uses a user configurable silence threshold that just reads in volume levels. In the future, we'd like to use a frequency-based approach that focuses on the human voice. We're also open to ideas, so let us know if you have any!
