DEVICE AND METHOD FOR GENERATING ENCODED STEREO SIGNAL OF AUDIO PART OR STREAM OF AUDIO DATA Russian patent published in 2009 - IPC H04S3/00 G10L19/00 

FIELD: physics; communications.

SUBSTANCE: invention relates to technology of multichannel audio and, specifically, to applications of multichannel audio in connections with headphone technologies. The device for generating an encoded stereo signal from a multichannel presentation includes a multichannel decoder (11), which forms three or more channels from at least one main channel and parametric information. Said three or more channels are subject to processing (12) headphone signals so as to generate an uncoded first stereo channel and an uncoded second stereo channel, which are then input into a stereo encoder (13) so as to generate an encoded stereo file at the output side. The encoded stereo file can be transmitted to any suitable playback device in form of a CD player or portable playback device such that, the user not only receives a normal stereo impression, but a multichannel impression as well.

EFFECT: efficient signal processing concept, which allows for multichannel quality playback on headphones in simple playback devices.
