Time-Frequency Processing of Spatial Audio

Document Thumbnail

[Feature] Time–frequency processing of spatial audio signals is an important area of current research. It enables elements of composite sounds to be isolated and managed selectively, and it is used in format conversion processes such as upmixing and downmixing. Time–frequency processing is also an important element of some low bit-rate coding schemes, and it is shown how stereo microphone signals can be processed directly for MPEG-Surround applications.
