Index MPEG-1 Audio Layer I

MPEG-1 Audio Layer I, commonly abbreviated to MP1, is one of three audio formats included in the MPEG-1 standard. [1]

10 relations: Audio file format, Digital Compact Cassette, Elementary stream, Media player (software), MP3, MPEG-1, MPEG-1 Audio Layer II, MPEG-2, Sub-band coding, 44,100 Hz.

Audio file format

An audio file format is a file format for storing digital audio data on a computer system.

Digital Compact Cassette

The Digital Compact Cassette (DCC) is a magnetic tape sound recording format introduced by Philips and Matsushita in late 1992 and marketed as the successor to the standard analog Compact Cassette.

MPEG-1 Audio Layer II

MPEG-1 Audio Layer II or MPEG-2 Audio Layer II (MP2, sometimes incorrectly called Musicam or MUSICAM) is a lossy audio compression format defined by ISO/IEC 11172-3 alongside MPEG-1 Audio Layer I and MPEG-1 Audio Layer III (MP3).

MPEG-2

MPEG-2 (a.k.a. H.222/H.262 as defined by the ITU) is a standard for "the generic coding of moving pictures and associated audio information".

Sub-band coding

In signal processing, sub-band coding (SBC) is any form of transform coding that breaks a signal into a number of different frequency bands, typically by using a fast Fourier transform, and encodes each one independently.

44,100 Hz

In digital audio, 44,100 Hz (alternately represented as 44.1 kHz) is a common sampling frequency.
