Hello Experts,
I need some help, I have a .mp3 file having duration of 31 minutes. I want to make it of 30 minutes, without losing any part of file,i.e, i don’t want to delete any part of my file.
Is it possible by changing its speed? If I increase its speed a little bit, it can become of 30 minutes, but how can i make it of exact 30 minutes, neither one second more , nor one second less of 30 minutes…
