Stereo Pre-built DirectX Example: Reverse Feedback Delay
HINT: YOU CAN CHOOSE ANY WAVEWARP DRAWINGBOARD AS A DIRECTX STEREO PLUGIN -- NOT JUST THE
ONES CONTAINED IN THIS "DirectX/Stereo" CATEGORY. WAVEWARP WILL AUTOMATICALLY CONVERT ANY
DRAWINGBOARD INTO THE REQUIRED FORMAT. THE PRE-CONVERTED EXAMPLES IN THIS DIRECTORY
ARE SIMPLY TO DEMONSTRATE THE EXPLICIT FORMAT OF STEREO DIRECTX DRAWINGBOARDS. SO, AFTER
YOU'VE TRIED THESE, JUST BROWSE TO ANY OTHER EXAMPLE DRAWINGBOARD IN THE ENTIRE DISTRIBUTION --
OR BETTER STILL, GO INTO WAVEWARP AND BUILD YOUR OWN!
This example illustrates another bizarre twist on the use of a simple digital delay as an audio effect. The input is reversed and added to
itself. The length of the reverse buffer corresponds to the delay length. The IIR filter is used to smooth the discontinuities
between successive flipped buffers. The effect is enhanced by feeding back the output of the filtered flipped signal back
into its own input.
Experiment with the delay and mixer settings to explore the interesting behaviour of this strange combination.
Widen the stereo field by adusting the left delay to be different from the right.
