• MPEG/audio provides a means of including ancillary data within the bitstream. In addition, the MPEG/audio bitstream makes features such as random access, audio fast forwarding, and audio reverse possible. 2. OVERVIEW The key to MPEG/audio compression is quantization. Although quantization is lossy, this algorithm can give "transparent",

The Microsoft Media Foundation MPEG-2 audio encoder is a Media Foundation transform that encodes mono or stereo audio to MPEG-1 audio (ISO/IEC 11172-3) or MPEG-2 audio (ISO/IEC 13818-3). The encoder supports Layer 1 and Layer 2 audio. It does not support MPEG-Layer 3 (MP3) audio. For MPEG-2, the encoder supports the Low Sampling Frequencies …

MPEG - 4 audio also includes a second perceptual audio coder, a vector - quantization method entitled Transform - domain Weighted Interleave Vector Quatitization (TwinVQ).This is aimed at low bitrates and allows the decoder to discard portions of the bitstream to implement both adjustable bitrate and sampling rate. The basic strategy of MPEG - 4 audio …
