Auto Surround Panner DirectX Plug-in Description:

The Auto Surround Panner is a specialize Auto Panner DirectX plug-in. This plug-in allows you to automatically pan from LEFT to RIGHT and/or FRONT to SURROUND. The surround encoder does not do all the necessary processing for high end surround encoding, but should be more than adequate for use as an effect. This plug-in really shines on guitars with delays or on any backing instrument or vocals.
Because of the nature of LCRS Matrix surround anything sent to exclusively to the surrounds will be 180 degrees out of phase. This means if you are using a Satellite/Sub Woofer for monitoring you will hear the low end (150Hz and below) drop out when the sound is coming from the surrounds only. You can use the CENTER control which will move the center panning point more towards the front speakers. You can also keep the width to 0.75 or below. That way the low end won't disappear completely.
There are controls for SPEED-FREQUENCY, HOLD TIME, CENTER, WIDTH, and SURROUND VOLUME. There are also two panning curves which are SIN and TRIANGLE, selectable Starting Positions as well as Speed Multipliers With this plug-in you can pan from left to right as well as from front to surrounds.
This plug-in requires DirectXMedia 7 or later to operate correctly.
