Scalable Tri-play Recording for Stereo, ITU 5.1/6.1 2D, and Periphonic 3D (with Height) Compatible Surround Sound Reproduction

Objectives: Take the next step toward reproducing human hearing AND make better recordings in 5.1. In life, we hear sources we see ' but also reflections and reverberation we don't see. Each sonic arrival is individually direction-stamped by our unique HRTF, including height, tonally colored by our pinna. Preserving 3D directionality is key to life-like hearing. A practical, scalable approach is presented (pat.pend.) - a way to "transform" 3D (full sphere) recordings for uncompromised 2D reproduction in stereo or 5.1/6.1 without any decoding. By adding a decoder and speakers, full 3D is losslessly 'reconstituted' from 6-channel media. Experimental "tri-play" 6-channel "PerAmbio 3D/2D" recordings have been made and demonstrations presented (114th Amsterdam 3/2003 & AES 24th Banff 6/2003) with praised results.
