Mid Side - does cable length affect the phase/delay of stereo result?

It is the nature of internet discussions for people to tell you what they know rather than what you need.

The OP's query was asked and answered....

The original poster was, I just used your reply as an easy jumping point to respond to the original question.

Sounds good to me boss.

@ccaudle and others, I for one really appreciate the detailed insights. I like to learn the truth about things and be a better and better person every day, so information related to the question at hand (in whatever context) are very much welcome. Pedantry be damned, haha!

Yes, but to me the question seemed so far fetched that it seemed worthwhile to try to pull the OP up a level in how to think about questions like that.
It just didn't seem very satisfying that if someone else asked the OP the same question, and questioned how he came to that conclusion, his answer would just be "John said so" without any understanding of why that was the case.

It was a good question from the OP ignoring the speed of electrical signal propagation through wires being extremely fast compared to the relatively pedantic audio wavelength/periods.

In other slower mediums sum and difference combinations of audio traveling over different path lengths (like through air) can interfere..... and for much higher frequencies than audio the propagation speed through wires can result in constructive or destructive interference (and more).

"No" was just my succinct answer to the original question. There is nothing wrong with more information but at some point it can get confusing "Blinding them with science".

Why is it though that I get a delay on my midi cable, that is 6 meters long when I play keyboard to my DAW? A 1 meter cable is unnoticeable when playing but when I used a 6 meter cable, there is a noticeable delay?

Just to be clear you are comparing the speed of an analog audio signal passing through wire vs, MIDI digital bit stream passing through wire. Apples and Grapefruit... not the same. There is propagation delay in both the midi send end and midi receive end.

The delay has nothing to do with the length of the midi cable. I recall experimenting with sending MIDI signals through 100' long audio snakes with no appreciable delay (while I wasn't measuring for that, I just wanted to see if it worked).

....... Electrons in a wire move at somewhere closer to a few millimeters per second.....

Drift velocity.
Approximately 10^-4 meter per second, or about one tenth of a millimetre.
