Trail Riding Edition
Our CDs (now Patented) contain over a thousand all-original recorded sounds made over a period of years. We have utilized the absolute latest digital recording technology, in portable form, to gather the sounds in pristine quality. To intensify and concentrate the training exposure, we have edited and layered the sounds into relatively short 'scenes'. Because of the CD's ability to loop and shuffle the tracks, these seemingly 'short' tracks can be extended indefinitely, and increased in volume until the horse is virtually immune to them. Furthermore, Gary Hedden's knowledge of the psychoacoustics of pinnae-related localization (how horses perceive the source of sounds) resulted in a unique recording and mixing technique. This technique actually simulates the ear and head movements of the frightened horse when responding to moving sound sources, and encodes that sound into the stereo signal. Our pictures show that the horses we tested are initially very curious about the sounds coming from the small boom box, because they seem to be coming from locations beyond the dimensions of the speakers. Extensive digital signal processing was employed in the mastering of these discs to make the utmost of the relatively limited playback fidelity of medium-grade boom boxes. Technical Details All of the CD tracks are originally recorded by us, using stereo MS (variable image width) microphone techniques and ultra low noise preamps. 24 bit conversion and storage is accomplished with a unique hand-held digital hard disc recorder. The individual sounds are then edited and mixed in a proprietary 32-bit floating point processor, and mastered with complex dynamic range reduction, so that the end result is consistent and aggressive audio level on the CD.
