Compared to other Audiogram tools I've used, this is really easy. Processing time is a bit long, but I did test it with a 2 hour podcast.

I have a couple feature suggestions that I think would be really helpful to podcast producers. Our show has mp3 chapters, and we also include matching time codes in our show notes. If you could read one (or both) of those you could suggest segments for users to clip out.

It would also be great if you could read a RSS feed and use that as an input in addition to uploading single files.
