MPEG-2 Part 3 (ISO/IEC 13818-3) defined additional bit rates and sample rates for MPEG-1 Audio Layer I, II and III. The new sampling rates are exactly half that of those originally defined for MPEG-1 Audio. MPEG-2 Part 3 also enhanced MPEG-1's audio by allowing the coding of audio programs with more than two channels, up to 5.1 multichannel. MP2 is the dominant audio codec in digital audio broadcasting and is also used in the production of Video CDs (VCDs). MPEG-1 Audio Layer II is defined in ISO/IEC 11172-3. An extension of MPEG-1 Layer II is defined in ISO/IEC 13818-3, which adds more sampling and bit rates as well as support for up to 5 audio channels. Production phase.
