I have big database of audio files, about 1-2 s long. Different people say different words, but during process I done some duplicates which I have to find and remove (database is about 100000 sounds and it is difficult to listen, have some noise, or are similar to human, but are different). Some duplicate audio files cant be shifted by half a second or less during cutting process.
Please help. How can I find real duplicates in my audio database?
