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 souComputer sound processingSoundRecording and reproducingDigital techniquesMultimedia systemsProgrammingComputer sound processing.SoundRecording and reproducingDigital techniques.Multimedia systemsProgramming.621.389/3621.3893Breebaart Jeroen1727806Faller Christof1727807MiAaPQMiAaPQMiAaPQBOOK9910841090103321Spatial audio processing4135648UNINA
