The acronym MIDI stands for Musical Instrument Digital Interface. The advantages for using MIDI with the techniques of compression of data are that they offer several advantages such as high speed, large size, good quality of sound, the facility of tempo control, the facility of instrument control, the facility of webmasters and the advantage of copyright restriction.
The spread of computing has led to an increase in the storage capacity of data. Now a larger volume can be stored on hard disks and stored over the Internet. The growth has led to the need for data compression. The term data compression is defined as the ability to reduce the storage amount or Internet bandwidth which is required to handle data. Most of the methods of data compression work in the same way as their names suggest. The following are the most prominent techniques of data compression. The most popular achievers and the methods of JPEG image compression and MPEG video and audio compression are as follows.
The techniques of lossless data compression are run length encoding, Huffman coding, arithmetic coding, LZ-77 encoding and LZW coding. The techniques of JPEG image compression are lossless and lossy image compression, luminance and chrominance image encoding or blocks, spectral conversion via DCT, quantisation, zigzag scan, lossless output encoding, JPEG summary and stream format, JPEG variants, JPEG-2000/JBIG and vector and fractal compression. The techniques of MPEG audio and video compression are MPEG-1 video compression, MPEG-1 audio compression 1 (waveform versus perceptual coding), MPEG-1 audio compression 2 (compression details), MPEG-2/AAC, other audio compression schemes and MPEG-4 and DIVX.
