Post Subject: How does this phase work?Posted by zanon on: 6/16/2010

I hope this is on-topic.

I want to understand more about effect of phase on audio.

There is a product, ZVOX, which is alternative to 5.1 surround for home movies. It is stereo system, but it has phase settings (which you can adjust) that make soundstage wider, or more narrow and focused. If you want more dialogue, you use phase to make sound field narrower, if you want "surround feel" without wires you use phase to spread everything out.

This is not about the benefits or problems with ZVOX, this is about how to use phase to narrow or widen sound stage (and by extension, impact of random phase, slightly out of phase etc.)

I am imaging amp that, when level goes up, automatically uses phase to widen sound field, and when level/content goes down, narrows it. I think it would be intersting, and it made me think of Lamm Factor X which you have mentioned Romy.
