In independent quality testing by organizations like MPEG and the European Broadcasting Union, aacPlus outperformed all other codecs in terms of audio quality per bit. Due to this performance, SBR was selected in 2001 as reference model for bandwidth extension technologies inside MPEG. Finalized last week in the results of the 64th MPEG meeting, High-Efficiency AAC (MPEG-4 aacPlus) is part of the core effort of MPEG to keep the MPEG-4 standard the most efficient and complete coding system on the market today.
Libraries and reference source code for MPEG-4 aacPlus encoders and decoders are available on Mac OS X, Win32, Linux, as well as multiple DSPs. Developers can contact Coding Technologies directly for immediate access to evaluation kits.
