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 sou 606 $aComputer sound processing 606 $aSound$xRecording and reproducing$xDigital techniques 606 $aMultimedia systems$xProgramming 615 0$aComputer sound processing. 615 0$aSound$xRecording and reproducing$xDigital techniques. 615 0$aMultimedia systems$xProgramming. 676 $a621.389/3 676 $a621.3893 700 $aBreebaart$b Jeroen$01646637 701 $aFaller$b Christof$01646638 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910830556903321 996 $aSpatial audio processing$93993746 997 $aUNINA
