I have hundreds of pairs of instrumental/vocal MP3 files. The instrumental version has music played with instruments. The vocal version does too, but it also has a vocal track overlaid.
I don't know what all processing went into creating these MP3 files, but I do know that the instrumental and vocal versions often do not have the same length, and they often start with a different length of silence.
I need to figure out what the offset is between each pair of MP3 files. Because there are so many of them, I would prefer a command line or batch solution.
I don't know anything about signal processing, I'm hoping for some existing tool that can easily do this. Any ideas?
