Signal Processing is a very mathematically oriented and intensive area forming the core of digital signal processing and it is rapidly expanding with new applications in every field of electrical engineering such as communications, control, radar, TV / Audio / Video engineering, power electronics and bio-medical engineering as many already existing analog systems are replaced with their digital counterparts.

The Digital Editing System, as Soundstream called it, consisted of a DEC PDP-11 / 60 minicomputer running a custom software package called DAP ( Digital Audio Processor ), a Braegen 14 "- platter hard disk drive, a storage oscilloscope to display audio waveforms to be edited, a video display terminal for controlling the system, and interface cards that plugged into the PDP-11's Unibus slots ( the Digital Audio Interface, or DAI ) that provided analog and digital audio input and output for interfacing to both Soundstream's digital recorders and conventional analog tape recorders as well.

Known variously as " Colorful KQV ," " Audio 14 ," " Groovy QV ," and " The Big 14 " over the years, KQV premiered its top 40 format on January 13, 1958, and is remembered for its high-profile, high-energy personalities, such as Chuck Brinkman, Hal Murray, Dave Scott, Steve Rizen, Dex Allen, Jim Quinn, future game show announcer Rod Roddy, and their large-scale promotion of a Beatles concert at Pittsburgh's Civic Arena ( now the Mellon Arena ) in 1964, and its former showcase studios at the Chamber of Commerce Building (" on the corner of Walk and Don't Walk ," as the DJs would say ) in downtown Pittsburgh, where the disk jockeys could be watched through a large window.

Audio frequency-shift keying ( AFSK ) is a modulation technique by which digital data is represented by changes in the frequency ( pitch ) of an audio tone, yielding an encoded signal suitable for transmission via radio or telephone.

In addition to being a media player, Windows Media Player includes the ability to rip music from and copy music to compact discs, burn recordable discs in Audio CD format or as data discs with playlists such as an MP3 CD, synchronize content with a digital audio player ( MP3 player ) or other mobile devices, and enable users to purchase or rent music from a number of online music stores.

Sony had originally intended for Digital Audio Tape ( DAT ) to be the dominant home digital audio recording format, replacing the analog cassette.

CCETT, IRT and Philips developed a digital audio two-channel compression system known as Musicam or MPEG Audio Layer II ( Emmy Award in Engineering 2000 ).

Other examples include dbx, Inc .' s Model 700 system, which, similar to modern Super Audio CDs, used a high sample-rate delta-sigma modulation rather than PCM ; Decca's 1970s PCM system, which used a videotape recorder manufactured by IVC for a transport ; and Mitsubishi's X-80 digital recorder, a 6. 4 mm ( ¼ in ) open reel digital mastering format that used a very unusual sampling rate of 50. 4 kHz.

One of these efforts, the Digital Audio Recorder Copycode Act of 1987 ( introduced by Sen. Al Gore and Rep. Waxman ), instigated by CBS Records president Walter Yetnikoff, involved a technology called CopyCode and required DAT machines to include a chip to detect attempts to copy material recorded with a notch filter, meaning that copyrighted prerecorded music, whether analog or digital, whether on LP, cassette, or DAT, would have distorted sound resulting from the notch filter applied by the publisher at the time of mastering for mass reproduction.

FLAC (; Free Lossless Audio Codec ) is a codec ( compressor-decompressor or coder-decoder ) which allows digital audio to be losslessly compressed such that file size is reduced without any information being lost.

AM radio technology is simpler than Frequency Modulated ( FM ) radio, Digital Audio Broadcast ( DAB ), Satellite Radio or HD ( digital ) Radio.

Audiophiles play music from a wide variety of sources including phonograph records, compact discs ( CDs ), and digital audio file formats that are uncompressed as well as ones that are compressed using lossless data compression such as FLAC, Windows Media Audio 9 Lossless and Apple Lossless ( ALAC ).
