Interesting Article on Time-Phase Coherence

Unread post by Simon Hickie »

Good article here which goes a long way to help explain why the Doc's speaker recipes and philosophy works. http://greenmountainaudio.com/speaker-t ... coherence/

Phrases like: "'Technology in the service of marketing' has led our industry astray over the past 20 years", "Measurements sell products", and "Test equipment will also be limited by the microphone used, as microphones have their own phase, tonal, and dynamic flaws. Even lab-calibration microphones can't resolve the same level of detail as the ear." should resonate somewhat.

Well join and tell him. Nick want more activity on the forum. It had become a cozy closed shop with no new ideas. Now people are thinking.

Well, from those Audio Talk test tones, phase is unimportant.
But, as per the Green Mountain link, music contains lots of transients.

From the Linn Exakt demo, my impression was that correcting phase made a nice little tweak, but it's no substitute for having a good set of drivers and a good speaker cabinet in the first place.

The Audio Talk test tones showed what happened in a gross sense, I cannot understand why you say it shows phase is unimportant IMO it showed the opposite, it is a worse problem with music.
