I have a recording (MTS file) of one of my favourite movies ("The Guns of Navarone") from free-to-air. Annoyingly, it is Audio Described. Can I suppress or delete this (to me) unwanted 'voice over'?
This free open-source AI software is truly amazing! Its typical use is to extract the lead vocal in a song leaving the background singers and instruments so it can be used as a karaoke track. I personally use it to get rid of background wind or fan noise. The results are far better than my attempt using audio tools to suppress the noise (I'm not an expert). So, it may actually work on the audio of your movie even if the voice over is on the same track.
But since this is one of your favorite movies, why not just purchase the DVD or Bluray on Amazon and enjoy the best quality! 😀
