FUTURE NEEDS TO CREATE NATURAL 3D AUDITORY EVENTS VIA MORE CHANNEL HEADPHONES FOR MPEG SURROUND PURPOSES

摘要

In the future "mpeg surround" will be the successor of the stereo "mp3". This portable technique evolutions need headphones, which offer 3D images of sound with a minimum of elevation effects and a virtual distance perception front and back. The past workshops and discussions during the 119. AES 2005 presented further problems like a compatible mixdown of 5.1 to 2.0 or 4.0 signals; not only the binaural head-related signal processing. As well it should be available standardised vario 3,5" jack for stereo or more channel surround. Herewith will be presented main basics how to realise this 3D auditory events via special multi channel headphone techniques plus a direct audio signal supply under the needs of a loudspeaker compatible reinforcement situation.
