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! 😀
I have a paid for audio removal tool and there is a real chance it would remover the dialogue from the movie as well, especially if the movie has a mono sound track. You could of course edit that track to put the dialogue back in after it is extracted to a new sound track. Sounds like a lot of work.
That plugin looks cool though. I may try it to see how many instrument tracks it can split an audio file into and how much degradation happens through removing a section.
I presume that the unwanted dialogue is mixed in with the dialogue of the film, correct?
In that case, you would need a tool to separate out the various voices and eliminate the one or ones that you don't want. Spectralayers Pro 11 does a pretty good job of this. It can separate out voices, then separate out various voices to separate tracks. I have yet to try this last part but will soon as I have a video clip with someone talking in the background at one point during a speech, and I want to remove this unwanted talking.
Unfortunately, it's expensive. I got it with an upgrade to Samplitude Pro X8 Suite. That blew my retirement budget for the year.
This doesn't help you much, but at least it's a possibility if nothing else works.
