  • mickey mouse program — (jargon)   The North American equivalent of a "noddy program", i.e. trivial. The term doesn't necessarily have the belittling connotations of mainstream slang "Oh, that's just mickey mouse stuff!"; sometimes trivial programs can be very useful.

  • mpeg-1 audio layer 1 — (audio, compression, algorithm)   (MP1) A simple 32-subband audio compressor using a floating point representation for subband samples. Resolution and scale factor are stored for groups of 12 subsamples. MP1 is only used for Philips DCC Digital Compact cassette with data rates of 384 kbps.
  • mpeg-1 audio layer 3 — (music, file format)   (MP3) A digital audio compression algorithm that acheives a compression factor of about twelve while preserving sound quality. It does this by optimising the compression according to the range of sound that people can actually hear. MP3 is currently (July 1999) the most powerful algorithm in a series of audio encoding standards developed under the sponsorship of the Moving Picture Experts Group (MPEG) and formalised by the International Organization for Standardization (ISO). MP3 is very different from Layer 2, using an additional MDCT layer to increase frequency resolution. Its scale factor groups are more optimised for the human ear, and it uses nonlinear sample quantisation and Huffman coding. MP3 files (filename extension ".mp3") can be downloaded from many websites and can be played using software available for most operating systems (also downloadable), e.g. Winamp for PC, MacAmp for Macintosh, and mpeg123 for Unix. MP3 files are usually downloaded completely before playing but streaming MP3 is also possible. A program called a "ripper" can be used to copy a selection from a music CD onto your hard disk and another program called an encoder can convert it to an MP3 file.
  • mpeg-2 audio layer 3 — (compression, standard, algorithm, file format)   An extention of MPEG-1 audio layer 3 for lower sampling rates (16-24 kHz) targeting bit rates from 32-64 kbps (possibly 8-160 kbps). It is often combined with MPEG-2 LSF.

  • ontological argument — an a priori argument for the existence of God, asserting that as existence is a perfection, and as God is conceived of as the most perfect being, it follows that God must exist; originated by Anselm, later used by Duns Scotus, Descartes, and Leibniz.
