[LAU] inverting phase of one channel - bad idea?

Hi A question came up on the chuck list today, regarding how to invert the phase of one channel. The poster wanted to use this "trick" to widen the width of the stereo image, and it sure does. However now I'm thinking if it's a good idea in the first place. Besides loosing mono-compatibility, I have a gut feeling that audio treated this way will become very uncomfortable or even annoying to listen to after a while. Does anyone have any thought about this? Should this "trick" simply be avoided or are there situations where using it on some parts of a mix would be ok (keeping in mind that the tracks in question will disappear in mono)? -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk
