MPEG-1 Audio MPEG doc#: N7703Date: October 2005Authors: B. Grill, S. Quackenbush MPEG-1 Layer I or II Audio is a generic subband coder operating at bit rates in the range of 32 to 448 kb/s and supporting sampling frequencies of 32, 44.1 and 48 kHz. 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

Introduction What does MPEG-1 Audio provide? A transparently lossy audio compression system based on the weaknesses of the human ear. Can provide compression by a factor of 6 and retain sound quality. One part of a three part standard that includes audio, video, and audio/video synchronization. 4. Technical Overview.

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: Generally used for final-state, end-user delivery. Relationship to other formats; Subtype of: MPEG-1, MPEG-1 Video Coding (H.261)
