Audio signal

An audio signal is a representation of sound, typically as an electrical voltage. Audio signals have frequencies in the audio frequency range of roughly 20 to 20,000 Hz (the limits of human hearing). Audio signals may be synthesized directly, or may originate at a transducer such as a microphone, musical instrument pickup, phonograph cartridge, or tape head. Loudspeakers or headphones convert an electrical audio signal into sound. Digital representations of audio signals exist in a variety of formats.

An audio channel or audio track is an audio signal communications channel in a storage device, used in operations such as multi-track recording and sound reinforcement.

Signal flow

Signal flow is the path an audio signal will take from source (microphone) to the speaker or recording device. It is most frequently in a recording studio setting, where the signal flow is often very long and convoluted as the electric signal may pass through many sections of a large analog console, external audio equipment, and even different rooms.

Track

Track or Tracks may refer to:

Electronics and computing

Entertainment

Song

A song is a single (and often standalone) work of music intended to be sung by the human voice with distinct and fixed pitches and patterns using sound and silence and a variety of forms that often include the repetition of sections. Written words created specifically for music or for which music is specifically created, are called lyrics. If a pre-existing poem is set to composed music in classical music it is an art song. Songs that are sung on repeated pitches without distinct contours and patterns that rise and fall are called chants. Songs in a simple style that are learned informally are often referred to as folk songs. Songs that are composed for professional singers are called popular songs. These songs, which have broad appeal, are often composed by professional songwriters, composers and lyricists. Art songs are composed by trained classical composers for concert performances. Songs are performed live and recorded. Songs may also appear in plays, musical theatre, stage shows of any form, and within operas.

Trail

A trail is usually a path, track or unpaved lane or road, though the term is also applied, in North America, to routes along rivers, and sometimes to highways. In the United Kingdom and the Republic of Ireland path or footpath is the preferred term for a walking trail. Some trails are single use and can only be used for walking, cycling, horse riding, snow shoeing, cross-country skiing, etc., others, as in the case of a bridleway in the UK, are multi-use, and can be used by walkers, cyclists and equestrians.

There are also unpaved trails used by dirt bikes and other off road vehicles. In some places, like the Alps, trails are used for moving cattle and other livestock (see transhumance). In the US historically, the term was used for a route into or through wild territory used by emigrants (e.g. the Oregon Trail).

Usage

In Australia, the term track can be used interchangeably with trail, and can refer to anything from a dirt road to an unpaved pedestrian path. The term trail gained popularity during World War II, when many servicemen from the United States were stationed in Australia, which probably influenced its being adopted by elements of the Australian media at the time (see Kokoda Track).

Audio (magazine)

Audio magazine was a periodical published from 1947 to 2000, and was America's longest-running audio magazine.Audio published reviews of audio products and audio technology as well as informational articles on topics such as acoustics, psychoacoustics and the art of listening. Audio claimed to be the successor of Radio magazine which was established in 1917.

History

Audio began life in Mineola, New York in 1947 as Audio Engineering for the purpose of publishing new developments in audio engineering. In 1948, the Audio Engineering Society (AES) was established and in 1953 they began publishing their definitive, scholarly periodical, the Journal of the Audio Engineering Society.Audio Engineering magazine dropped the word "engineering" in 1954 and shifted to a more consumer- and hobbyist-oriented focus while retaining a serious scientific viewpoint. In 1966, Audio's headquarters were moved to Philadelphia and the periodical was printed by North American Publishing Company.

In 1979, CBS bought Audio from its Philadelphia publisher and moved operations to New York. CBS then bought a group of magazines from Ziff-Davis, including sometime competitor Stereo Review, which soon found itself sharing office space (but not staff) with Audio. In October 1987, Peter Diamandis led a management buyout of the CBS magazine division with 19 magazines with $650 million of financing from Prudential Insurance. Diamandis Communications Inc. soon sold seven magazines for $243 million and in April 1988 sold Audio and the rest of the magazines to Hachette Filipacchi Médias for $712 million. Peter Diamandis remained in control of the magazine group and in 1989 bought competing audio magazine High Fidelity and merged its subscription and advertiser lists with those of Stereo Review, firing High Fidelity's staff and shutting down its printing.
