I'm looking for some kind of application that'll let me organize all my audio samples. They are all .wav files of various length. I would like to be able to sample them using categories (drum samples, bass samples) etc. I tried doing it with iTunes, but it won't allow me to add .wav files. I've also tried using lots of directories, but I didn't really like that approach. So, is there some kind of application specializing in sorting audio samples? I'm willing to pay for such an application.
