Detect duplicate music files

Question

I have two directories containing ~ 20 GB of music files (mostly mp3, some ogg), and I would like to detect all duplicate songs. There are two complicating factors:

• A song can contain different file names in two directories.
• Two files containing the same song can have different ID3 tags and therefore have different checksums.

What is a good approach to solving this issue?

Answer 1

As I said about this in the past, you need to use genpuids that come from Music IP. Closed source software creates an audio fingerprint of a file regardless of format, id3, checksum, etc.

Answer 7

How about something like this: find a library to get the length of the mp3, as well as a pointer to the audio data (there seem to be several libraries that can do this), do a first pass filter based on the song's length, and for songs that have a consistent length, check your audio data. Similarly, a script for finding duplicate files / images .

Some adaptation of ffTES did a great job for me for a very similar task.
