This section provides a reference guide to Intel IPP for SBR audio decoder. Figure shows the audio decoder pipeline that supports SBR technology.
Figure shows the common pipeline of SBR decoder.
In accordance with the EC126 standard the SBR decoding technology can operate on complex-valued signals in the mode called High Quality (HQ) or on real-valued signals in the mode called Low Power (LP)). On the other hand, the SBR decoding technology can produce output signals with core sample rate or double sample rate. All these modes are supported by Intel IPP for SBR audio decoder.
