First, I am using version 2.1.1 and my OS is Windows 10.
I have cut out a song from a movie that I can’t find to buy online or as a CD, the soundtrack was never released. I want to remove the movie voices from the song, while leaving the song vocals in intact.
I have cut the whole movie down to about 2:40 minutes of what I want to keep, with four tracks, the movie came in a ac3 file with six tracks. The tracks I have are Mostly sounds (the song I want to keep) Left, right, Movie voices, and base.
After playing the song over and over again, while also playing around with the Movie voices track, I have found that the voices seem to spill over during the first 30 seconds and I can see them on the graph, while playing.
I’ll try and say this another way, I have two tracks with a song I want to keep, but it has a some voices in the background. I do have another track with ‘JUST’ the voices.
How can I removed the spoken voices using the track three or the voice only track as a base?
The idea is that you make a stereo track with “music + voice” in one channel and “voice only” in the other channel.
Initially you would just set the two mono tracks so that one is Left and the other is Right (see “Mono, Left Channel and Right Channel”: http://manual.audacityteam.org/o/man/audio_track_dropdown_menu.html#Splitting_and_Joining_Channels) but do not join them as a stereo track - keep them as separate Left and Right single channel tracks.
Use the Amplify effect one the track with the louder voice to bring the level of the voice down so that it matches the level of the voice in the other track.
Hint: If you use good headphones and if you are able to match the voices exactly (which may not be possible), it will sound as if the voice is in the middle of your head and the music is over to one side.
Get that as close as you can, then join the two tracks to make a single stereo track and apply the “Vocal Reduction and Isolation” effect.
There are no guarantees that this will work, but it is probably your best shot.
