I find the background music in many videos that are designed to inform and educate very annoying.
The sound quality is often not brilliant anyway and the music simply drowns out the dialogue and kills the video. Does anyone know of any software
that will enable me to remove the music from videos without removing the dialogue.
To put it blankly, NO!! there are many DAWs (digital audio workstations) out there cubase being one of them that would be a starting point, I use
reason 5 and Ableton live. But to take a soundtrack of music and vocals mixed together and then remove the music leaving the vocals is nearly an
impossible task unless you have some clever tricks up your sleeve.
If the video you are watching has more than one audio track (which i doubt) with the vocals on one track and the music on the other then just mute the
music channel. But to take the music out requires that you have the music track aswell without the vocals, then its a case of mixing the original
(music & vox) with the music only track, inverting the music only track and slightly phasing it, would have the effect of cancelling out the music
only not perfectly, its tricky, very tricky and you really need to be and audio engineer and expert to pull it off and you will still be left with
elements from the music that take up the same frequencies as the vocals. its easier the other way around, to remove the vocals as they take up
particular frequency bands where as a music track has a much wider frequency range and harder to eliminate.
Usually vocals are the main part of a song and are recorded in the centre of the soundstage, therefore you can use a technique called centre killing
to remove frequencies that aren't panned hard left and hard right, this means that the majority of the vocals will be gone but also any elements of
the music track that existed there will also be gone.
Here is a link to what you require and you'll see that its probably not worth the hassle. Not only are you going to have to convert the video into an
audio track, you'll then need to find an instrumental version of the audio track aswellc(good luck with that bit!) then you are gonna have to go to
work in the DAW you are using to end up with what are usually less than desirable results. This guy has the right idea, and achieves what you
need,check it out......
