Hello,
The idea is to isolate out-of-phase sounds from a stereo recording.
It needs to be spectral.
Melda have it's brother, MCenter..

Flip the polarity of one channel. Sum to mono. Done.

Err, nope. What the guy above you suggested is exactly what you asked for "the out of phase stereo components" are just the stereo difference. The
stereo difference isn't the left and right. extracting the actual left/right/center components requires decorrelation algos (like Leapwing Audio CenterOne, MCenter also possibly, though not sure as i've never used it)
If the latter is what you are after try those and there is also the free but a bit meh Bertom Audio Phantom Center. What you requested though is what Jupiter8 responded with

I think the OP wants to find a way to limit the stereo width so nothing ever 100% cancels anything.
If not, I don’t have the slightest idea of what to do with this...

Yes. Mono panned Left and Right would be isolated too.DJErmac wrote: Sun Apr 13, 2025 9:59 pm I think the OP wants to find a way to limit the stereo width so nothing ever 100% cancels anything.

DMI Studio SpaceControl and RSJ Sideminder then? those are "correlation limiters"DJErmac wrote: Sun Apr 13, 2025 9:59 pm I think the OP wants to find a way to limit the stereo width so nothing ever 100% cancels anything.

Hi,
An out-of-phase signal is a STEREO signal. When panned center, both channels are playing the same frequency with inverted amplitude. This signal, when summed, will resume to ZERO, but only in the electronic/digital domain. In a stereo system, it won't do the same Null.
Lower frequencies will cancel more efficiently, higher frequencies won't cancel at all. Psychoacoustically, an out-of-phase signal will appear to be closer and wider to the listener. The smaller the acoustic space, the better they cancel (except headphones).
But it is possible to pan, for example, a LEFT-CENTER out-of-phase signal.
In this case, the left channel will produce a stronger signal than the right channel, just like in a normal signal.
When applied to a full mix, it gives an interesting result..
Traditionally inverting one channel and summing both, will give a mono signal, and also contain enveryting except the center mono content, gradually increasing amplitude as the signal is far from the center. Out-of-phase will be 6dBs louder.
The only way to do this is with FFT... I can do it using Bidule spectral modules, but the quality of the FFT is standard..

Theoretically, if it were physically possible to place two identical speakers in the same physical location, one of which is playing a signal exactly inverted from the other, they would null.
The reason they don't null in practice is, those speakers are not in the same location. But they might cancel out at different frequencies depending on the acoustics and listener's position.
With headphones, you'll hear the signal in both ears, nothing will cancel. But it can be pretty unpleasant to listen to - some content can even cause vertigo for some listeners.
Ever since a mastering engineer advised me about phase correlation I've always been careful with it, and gotten better stereo images as a result.
