High-Fidelity Multichannel Audio Coding Second Edition
Preface Audio is one of the fundamental elements in multimedia signals. Audio signal processing has attracted attention from researchers and engineers for several decades. By exploiting unique features of audio signals and common features of all multi-media signals, researchers and engineers have been able to develop more efficient technologies to compress audio data. Although books on digital ...
متن کاملHigh-fidelity multichannel audio coding with Karhunen-Loeve transform
A new quality-scalable high-fidelity multichannel audio compression algorithm based on MPEG-2 Advanced Audio Coding (AAC) is presented in this research. The Karhunen-Loève Transform (KLT) is applied to multichannel audio signals in the pre-processing stage to remove inter-channel redundancy. Then, signals in de-correlated channels are compressed by a modified AAC main profile encoder. Finally, ...
متن کاملUltra 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...
متن کاملDesign 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...
متن کاملHigh-Fidelity PWM Inverter for Digital Audio Amplification: Spectral Analysis, Real-Time DSP Implementation, and Results
A complete digital audio amplifier has been developed, implemented and tested. The process is entirely computational, and the output load and filter are the only analog components in the system. The process makes use of digital signal processing and a switching power stage to provide both high fidelity and high efficiency, beginning with a digital audio data stream. The advantages of naturally-...
