The goal of spatial audio coding is to data compress multi-channel audio material by combining channels into a composite signal and transmitting supporting side-information so that a decoder can reconstruct an approximation of the original signal from the composite.

Recently, a new approach in low bitrate coding of stereo and multi-channel audio has emerged: Spatial audio coding permits an efficient representation of multi-channel audio signals by transmitting a downmix signal along with some compact spatial side information describing the most salient properties of the multi-channel sound image. Besides its

efficiency, Spatial Audio Object Coding (SAOC) is one of the recent standardization activities in the MPEG audio group. SAOC is a technique for efficient coding and flexible, user-controllable rendering of multiple audio objects based on transmission of a mono or stereo downmix of the object signals. The SAOC system extends the MPEG Surround standard by re-using its spatial …

Spatial audio coding (SAC) [1, 2] is a compression approach proposed recently to efficiently encode multichannel audio signals. Rather than individually encoding the audio signal in each channel, the multiple audio signals are simply represented as a mono or stereo audio signals, named down-mix signals, which can be encoded further by any type of audio encoder.

Various efficient implementations (published and new unpublished) of the forward and backward MDCT in the MP3 audio coding standard developed in the time period 1990–2010 have been described, including the efficient implementation of polyphase filter banks for completeness. For each efficient forward/backward MDCT block transforms implementation have been …
