I have a MP3 file where each line of the song is repeated thrice. When I hear it closely, what they have done is they have taken the whole song and somehow identified where each line ends (maybe they have their identifier as the 1 second silence between each line), copied the line and pasted it twice.
The reason why they have done this is, so that we will be able to memorize it easily. Now, what I want is the opposite. I want a software/method, where I identify the gap i.e., 1 second gap and then chop of the repeating 2 instances of the same line.
How do I do it and what software would best be suited for this?
