- Penteo
Penteo is a digital audio re-mastering process assembled by John Wheeler of Berkeley, CA for professionally converting existing
stereo recordings to 5.1surround sound (stereo upmixing) by using a DSPcross-correlation algorithm . The process is able to cleanly parse out and recover individual sounds which the original mixer channeled to the left, center, and right panorama locations of a stereophonic mix, with discrete separation between the channels.The Penteo process is a forensic analysis of a
stereo mix, comparing waveforms found in the left and right channels, resulting is a re-creation of the original stereo mix in a 5.1 soundfield.Alternatively, the left, center, and right can be used as an all-front 3.0 mix, replacing the stereo phantom center with a real one.
It was first demonstrated publicly at the Surround Expo in Los Angeles in 2005. It is being used extensively for production of classic rock surround source material for the
HD Radio surround broadcast program atWZLX Boston. [cite web|url=http://www.rwonline.com/pages/s.0054/t.6776.html|title=WZLX: Programming a Surround Station|author=Skip Pizzi|publisher=Radio World Magazine|date=June 2007|accessdate=2007-10-12]References
