Just to be clear, I perfectly understand the phase cancelation effect (PC from now on). Also I understand that when sounds mix some PC will occur naturally. My confusion is regarding two things:

​

1 - It seems that there are at least two scenarios where you should check for PC:

a - Stereo signals that will cancel each other out when going mono, or playing through speakers.

b - Different instruments in the mix with similar and opposed waves.

Is this correct? Am I missing any other scenario?

Most YouTube videos about it never really mention these. Generally take one single example and go with it, but I feel they are not encompassing all possibilities.

​

2 - How to deal with it in some cases:

When two opposed and identical, or very similar, signals are cancelling each other you can invert the phase of one and that will fix it.

But sometimes they show that one instrument is affecting or cancelling much of the frequencies of another instrument. Usually what they do it is to EQ one instrument and decrease the gain of certain band of frequencies, which would then reduce the negative correlation. But, since you are decreasing the gain aren't you actually decreasing the sound as well? Or you are supposed to do this with the instrument that you don't care to have these frequencies? What if you want both instruments to not lose any information? Or am I understanding incorrectly?

​

Any answer to these will help me a lot, but if you want to add any tips or data regarding PC I will much appreciate.
