MPEG (MPEG Video) is a video format by the Moving Picture Experts Group. The file extensions can be.mpeg,.mpg,.mp1,.mp2,.m1v,.mpv. MP3 (MPEG1/2 Audio Layer 3) is an efficient and lossy compression format for digital audio, offers a variety of different bit rates, an MP3 file can also be encoded at higher or lower bit rates, with higher.

MPEG-1 Audio Layer I, commonly abbreviated to MP1, is one of three audio formats included in the MPEG-1 standard. It is a deliberately simplified version of MPEG-1 Audio Layer II, created for applications where lower compression efficiency could be tolerated in return for a less complex algorithm that could be executed with simpler hardware requirements. While supported by most media players, the codec is considered largely obsolete, and replaced by MP2 or MP3.

For files only containing MP1 audio, the file extension .mp1 is used.

A limited version of MPEG-1 layer I was also used by the Digital Compact Cassette format, in the form of the PASC (Precision Adaptive Subband Coding) audio compression codec. The bit rate of PASC was fixed at 384 kilobits per second.

MPEG-1 Layer I is defined in ISO/IEC 11172-3, which first version was published in 1993.

  • Sampling rates: 32, 44.1 and 48 kHz
  • Bitrates: 32, 64, 96, 128, 160, 192, 224, 256, 288, 320, 352, 384, 416 and 448 kbit/s[5]

An extension has been provided in MPEG-2 Layer I and is defined in ISO/IEC 13818-3, which first version was published in 1995.

  • Additional sampling rates: 16, 22.05 and 24 kHz
  • Additional bitrates: 48, 56, 80, 112, 144 and 176 kbit/s[5]

MP1 uses a comparatively simple sub-band coding, using 32 sub-bands.[6]
