商品描述

This book collects a wealth of information about spatial audio coding into one comprehensible volume. It is a thorough reference to the 3GPP and MPEG Parametric Stereo standards and the MPEG Surround multi-channel audio coding standard. It describes key developments in coding techniques, which is an important factor in the optimization of advanced entertainment, communications and signal processing applications.

Until recently, technologies for coding audio signals, such as redundancy reduction and sophisticated source and receiver models did not incorporate spatial characteristics of source and receiving ends. Spatial audio coding achieves much higher compression ratios than conventional coders. It does this by representing multi-channel audio signals as a downmix signal plus side information that describes the perceptually-relevant spatial information.

Written by experts in spatial audio coding, Spatial Audio Processing:

  • reviews psychoacoustics (the relationship between physical measures of sound and the corresponding percepts) and spatial audio sound formats and reproduction systems;
  • brings together the processing, acquisition, mixing, playback, and perception of spatial audio, with the latest coding techniques;
  • analyses algorithms for the efficient manipulation of multiple, discrete and combined spatial audio channels, including both MP3 and MPEG Surround;
  • shows how the same insights on source and receiver models can also be applied for manipulation of audio signals, such as the synthesis of virtual auditory scenes employing head-related transfer function (HRTF) processing and stereo to N-channel audio upmix.

Audio processing research engineers and audio coding research and implementation engineers will find this an insightful guide. Academic audio and psychoacoustic researchers, including post-graduate and third/fourth year students taking courses in signal processing, audio and speech processing, and telecommunications, will also benefit from the information inside.

商品描述(中文翻譯)

這本書將關於空間音頻編碼的豐富資訊集結成一個易於理解的專書。它是對3GPP和MPEG Parametric Stereo標準以及MPEG Surround多聲道音頻編碼標準的全面參考。書中描述了編碼技術的關鍵發展,這是優化先進娛樂、通信和信號處理應用的重要因素。

直到最近,用於編碼音頻信號的技術,如冗餘減少和複雜的源和接收模型,並未納入源和接收端的空間特性。空間音頻編碼實現了比傳統編碼器更高的壓縮比。它通過將多聲道音頻信號表示為混音信號加上描述感知相關空間信息的附加信息來實現。

《空間音頻處理》是由空間音頻編碼專家撰寫的,該書:

- 回顧了心理聽覺學(聲音的物理測量和相應知覺之間的關係)和空間音頻聲音格式和重現系統;
- 將空間音頻的處理、獲取、混音、播放和感知與最新的編碼技術結合在一起;
- 分析了用於高效處理多個離散和結合的空間音頻通道的算法,包括MP3和MPEG Surround;
- 展示了相同的源和接收模型的見解如何應用於音頻信號的處理,例如使用頭部相關轉換函數(HRTF)處理和將立體聲轉換為N聲道音頻上混音的虛擬聽覺場景的合成。

音頻處理研究工程師和音頻編碼研究和實施工程師將會發現這是一本富有洞察力的指南。學術界的音頻和心理聽覺研究人員,包括攻讀信號處理、音頻和語音處理以及電信專業的碩士和三/四年級學生,也將從其中獲益。
