Audio DiffMaker: throwing the cat amongst the pigeons

[xenithon]

Hi all. First and foremost, a disclaimer - please do NOT shoot the messenger. I do not support, agree, disagree, or have any feelings or thoughts or conclusions or associations whatsoever with the following

Audio DiffMaker: ...is a freeware tool set intended to help determine the audibility of things intended (or expected) to change sound quality in an audio playback system. It finds the absolute difference between two audio recordings.

The difference recording that results is only what has changed between the two recordings. If anything - a change of component, a treatment, mechanical damping, etc. - is having any audible effect on the audio signal in a system, the difference recording will have audible content. The end result is primarily intended to be evaluated by ear....

The nitty gritty can be read up on the site

In a world where a flyspeck can cause drastic changes in sound reproduction, i would have expected a tiny tad more resonance.

The procedure used in the programm mentioned above is nothing new. It's one of the reasons why it's usually rather hard to find a technically skilled person beeing a cable cultist at the same time.

The fact that no manufacturer or hifi-mag utilizes it for marketing purposes, makes it very likely

there are no differences to be found bigger than the inaccuracies of todays recording technologies. Which is, actually, pretty small.

In other words: Whatever differences we may talk about here (that may be not presentable with this method), they have to be so small they don't survive a single A/D conversion.
