"Stereoizing" Mono Signals with the Haas Effect
« on: March 09, 2011, 12:19:43 pm »

I read an interesting article by David Moulton on "stereoizing" mono signals. He said that the Haas effect is a great way to "stereoize" a mono sound source.  (The Haas effect being very short .1 to 1ms delay).  Moulton also said that one should only pan a source signal hard left, center, or hard right and that the Haas effect can be used to fill up the "imaginary space" between these points.

How exactly would one use such a delay in mixing?

Let's say I've panned a mono synthesizer sound hard left. If I wanted to "stereoize" that mono sound with the Haas effect, would I use a short stereo delay and pan the effects return, or would I use a short mono delay and just pan the signal of the bus itself?

I've never panned my sends, (just the effects busses themselves).  Perhaps I've overlooked something...

Half understood nonsense.

To say that "the Haas effect" means sub-millisecond delays is inaccurate.

there's NO magic way to stereoize a mono signal, Every benefit has a price. -Go ahead, choose ANY delay from 0.1mS to 10mS, and listen to what it does in mono.

There is no free lunch, anyone who tries to 'authoritize' any approach with a misapplied term either doesn't know what they're talking about, or is being extremely disingenuous.

The Haas effect refers to ambiguity and localization, and is frequently misused as a term. Most people use it wrongly, ten seconds with Google gives a better idea.

I have the feeling that I have more experience in my little finger than you do in your whole body about audio electronics..

Hmm...this is the article in reference.

So how do you, Keith, treat your mono signals (besides the obvious ones that go untreated like bass and drum sounds)?

The article is not about turning mono into stereo. It's about delay panning vs intensity panning.

A delay as short as a single sample can create all kinds of phase havoc... that has nothing to do with stereo and everything to do with comb-filtering... as Bruno said - the article is about localization of a panned signal - not "stereo-izing" but the placement of sounds in a stereo field.

Peace.
