You can create a stereo file combining the center channel with the left or right channel, and then run it thru CenterCutGui using the "Sides" channels option.If the background music is the same in the source center channel as in the source front channels, then it will be sent to the output center channel while removed from the output side channels.Something likeAM + BM = A + MM + Bwhere A is the center channel, B is either left or right channel and M is the background music.
The only way of doing C-(L+R) is by using 180° phase shifting on the L/R channels, then when muxed together C and L/R, the music will cancel itself out but the rest of the info in L/R will be added to C, only 180° phase-shifted.
Does the background music in both the original centre channel and right/left channel have to be the same amplitude/volume? Because the left and right channels are quieter than the background music in the centre channel.
Also, should the stereo channel I create be left/right stereo or mono/mono stereo?
I need extract dialogue from other sound too. Can someone write guide how to do it? I want to change dialogue in movie, but both dialogues has differents backround sounds.
...in center track of all my tracks are dialogues with other sounds.
So, I need from two track keep or extract only dialogues from center channel (It' seems, that igregon solved it)
I tried center Cut gui, but without succes.
Please, can someone help how can I make 180° phase-shifted?? Which audio editor has this function?
Probably almost every editor can do this. Personally, I know about Audacity and SoX. The function is often called “invert waveform” or similar, because a 180° phase shift is equivalent to inverting the sign of each sample (e.g., change +0.83 into -0.83).
