Their signals are cancelling out because they are in phase, this is a thing. It describes what is happening and why. You are arguing semantics here more than a technical point here, from my perspective. I agree with the physical reason, just because it is simple does not mean you cannot have a term for it in the case.
- mbell 14y agoI am in a way arguing semantics because I believe its confusing to non EE people reading this to use a term like 'phase cancellation' in a way that is very different from its usage in almost every other context. In general it refers to the sum of two waves equaling zero (or some reduced value), i.e. destructive interference. In this case the opposite is happening and the vocals are removed not due to a sum of the waves but rather a difference equating to zero. Side note - welcome to hacker news! Assuming your the same kortuk from the EE stack exchange I believe we've interacted a few times.

- kortuk 14y agoYes, we have interacted there a few times. I would probably use the term "common-mode cancellation." But it is something that is a very base concept in EE and the other terminology makes sense to me, although for non-EE I could see the issue. You should make hacker news your website on EE? Your account looks some bare there, add some information!
