Editing Audio

[The Shogun]

Im trying to take some of the talking at the end of the song out but keep the beat going, any Ideas?

If the beat is repetitive enough it should be fairly easy to do. For editing audio I use Audacity. It should be easy to find with a Google search.

I too, would like to know how to eliminate voices, but keep the music. I'm not sure how to do this in Audacity, so any help that we, The Shogun and myself, could receive on this topic would not go unappreciated.

Eliminating vocals is very hard to do, even in the best programs. The exception is if for some reason the vocals are located on a separate track like in some DVD 5.1-channel surround sound mixes. Sometimes you may be able to track down a non-vocal karaoke track (J-pop singles used to have these a lot a few years ago, now I only see them for anime CDs occasionally).

Theoretically, if you can isolate the vocal somehow, you can use it to subtract it from the music by creating a negative waveform of the vocals and applying it. If the song is stereo, one way is to subtract the right channel from the left channel assuming the vocal is on both and of equal level. Then take this resultant mono vocal track and subtract it from both left and right channels of the original stereo recording. Of course, any other sounds that are also the same on both left and right channels are affected, meaning you'll usually end up eliminating more than just the vocals.

As for The Shogun's case, I assumed that there was a portion of the end of the song that did not have the speaking on them but big enough of a chunk and repetitive enough that he could copy and paste that portion over the spoken parts. Or cut off the end with that spoken part and tack on enough of the repeated beat part to go on long as he wanted.

Good luck.

Oops! I re-read my post and I think I found an error (or at least a somewhat simpler alternative).

It should go like this:

You can try to eliminate the vocals of a stereo recording by taking the left channel and creating a negative of it, then applying this negative left to the right channel. The resultant right channel should have no vocals left if the singing/speaking is dead center on the recording (same levels L & R). Now repeat the process for the left channel by making a negative of the right and applying it to the left. Again, if there are sounds that are present on both the L & R channels at the same levels similar to how the vocals are, they also will be eliminated.

if it is for the anime: just mute the clip, but if you want to eliminate just the vocals, that is too advanced for simple programs

it it is for music: you really cant unless there is a instrumental version that exists
