Batch process lead-ins

I have a ton of mp3’s, all with different lead-in lengths. Is there a way to set them all to 2 seconds, for example?

I don’t think I understand the question.

Do you have songs where the introduction music before the main theme is different lengths? you’re stuck with that. We can’t take the music apart and put it back together.

Or do you have silence at the beginning and each of the silences is different?


The lead-in silence on my tracks can very between 0 seconds and 12 seconds. I would like to set it to 2 seconds. I have close to 12,000 mp3’s to adjust, so a batch process or a chain would be good.
