I have podcast audio files which contain ad breaks. Before and after each ad break, a distinct sound effect is played that lasts a couple of seconds. First, I want to know how I can locate all the occurences of this distinct sound within my audio file. How can I fingerprint a sound clip and then search for this sound in my whole audio file? Second, I want to match all pairs of this sound and cut the audio inbetween each pair. How can I do that?
