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.

Abstract This chapter describes the MPEG-2 Audio coding family which was developed to extend the MPEG-1 Audio functionality to lower data rate and multichannel applications. First we will discuss MPEG-2 LSF and “MPEG- 2.5” systems in which lower sampling frequencies were used as a means to reduce data rate in MPEG-1 audio coding.

Audio in an MPEG-2 transport stream It supports MPEG-1 layers I and II and MPEG-2 low sampling frequency (LSF) extensions Input samples must 16 bits per sample, with an audio sampling rate of 48, 44.1, 32, 22.05, or 16 KHz. The encoder cannot resample the audio stream; the encoded audio has the same sample rate as the input.

Typical bit rates for Layer II are in the range of 128-256 kbit/s, and 384 kb/s for professional applications. MPEG-1 Layers I and II (MP1 or MP2) are perceptual audio coders for 1- or 2-channel audio content. Layer I has been designed for applications that require both low complexity decoding and encoding.

MPEG-2 Part name: Advanced Audio Coding The MPEG-2 AAC standard is a new, state of the art audio standard that provides very high audio quality at a rate of 64 kb/s/channel for multichannel operation. It provides a capability of up to 48 main audio channels, 16 low frequency effects channels, 16 overdub/multilingual channels, and 16 data streams.

MPEG-1 and MPEG-2 Layer II Audio Encoding. Description. Lossy audio compression that derives from the MUSICAM audio codec. This format may be referred to as MP2 and employs perceptual compression. This means MP2's compression takes out information that is imperceptible in the human auditory range. MP2 is the dominant audio …
