چکیده

The introduction of new techniques for audio reproduction such as binaural technology, Wave Field Synthesis and Higher Order Ambisonics is accompanied by a paradigm shift from channel-based to object-based transmission and storage of spatial audio. The separate coding of source signal and source location is not only more efficient considering the number of channels used for reproduction by large loudspeaker arrays, it will also open up new options for a user-controlled soundfield design. The paper describes the technological change from stereophonic to array-based audio reproduction techniques and introduces a new proposal for the coding of spatial properties related to auditory objects.

Design of a High Range, High Efficiency Spread Spectrum Transmitter for Audio Communication Applications

This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...

High-definition digital audio in 3-dimensional sound reproduction

The principles of high-definition, S-dimensional digital audio are reviewed as applicable to DVD in terms of PCM and bitstream formats. A case is presented in favour of both extended dynamic range and extended bandwidth and methods of implementation discussed. Lossless compression is also supported together with multi-channel encoding, while aspects relevant to converter parameters and band-lim...

Ultra high-resolution spatial audio technology for HDTV on DVD

High capacity optical storage and wide band networks facilitate the delivery of ultra high-resolution audio (UHRA). It is proposed that future high-definition television (HDTV) formats should embrace not only enhanced video but also enhanced audio designed for extended bandwidth, bit depth and spatial resolution. Key ideas are summarised including an ultra high-resolution source code format, ef...
