Multichannel audio is attracting rapidly increasing popularity in audio reproduction. In most cases, however, its transmission requirements are extremely demanding compared to the available bandwidth. One possible solution to this problem could be to transmit a reference channel and recreate the remaining channels at the receiving end. Such a method is proposed by taking advantage of spectral conversion techniques that have been successfully applied to speech processing. Applications of the proposed system include transmission of multichannel audio over the current Internet infrastructure and, as an extension of the methods proposed here, remastering of existing monophonic and stereophonic recordings for multichannel rendering.
