Free Stereo Effect, Haa5, For Mac & Windows

Haa5Apex Audio has released a free plugin, for Mac & Windows, Haa5.

Haa5 uses stereo delays to create what is known as the “precedence effect”, also known as the “Haas effect” after Helmut Haas, whose 1949 Ph.D. thesis first described this psycho-acoustic phenomenon.

The Haas effect creates a sense of direction by using the same system our own ears use to locate sounds in the natural world. By creating a slight delay between the left and right signals the listener perceives a sense of direction depending on which ear hears the signal first. So, if the right signal is delayed, then the left ear will pick up the sound first, causing the sound to seem to come from the left; and vice versa.

Using the Haas effect, one can create a much more attuned and surgically precise stereo image. And, because the concept relies on psycho-acoustics, the Haas effect lends itself to a much more natural panning effect than standard rotary potentiometer panning, which merely adjusts the volumes of the left and right signals separately to create an artificial and less real sense of direction.

Haa5 is a free (name your own price) download from the Apex Audio site. If you’ve used it, leave a comment and share your thoughts on it!
