Audiobook
An audiobook (or a talking book) is a recording of a book or other work being read out loud. A reading of the complete text is described as "unabridged", while readings of shorter versions are abridgements. Spoken audio has been available in schools and public libraries and to a lesser extent in music shops since the 1930s. Many spoken word albums were made prior to the age of cassettes, compact discs, and downloadable audio, often of poetry and plays rather than books. It was not until the 1980s that the medium began to attract book retailers, and then book retailers started displaying audiobooks on bookshelves rather than in separate displays. Etymology The term "talking book" came into being in the 1930s with government programs designed for blind readers, while the term "audiobook" came into use during the 1970s when audiocassettes began to replace phonograph records. In 1994, the Audio Publishers Association established the term "audiobook" as the industry standard. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ''Audios headquarters were moved to Philadelphia and the periodical was printed by North Amer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Audio
Digital audio is a representation of sound recorded in, or converted into, digital form. In digital audio, the sound wave of the audio signal is typically encoded as numerical samples in a continuous sequence. For example, in CD audio, samples are taken 44,100 times per second, each with 16-bit sample depth. Digital audio is also the name for the entire technology of sound recording and reproduction using audio signals that have been encoded in digital form. Following significant advances in digital audio technology during the 1970s and 1980s, it gradually replaced analog audio technology in many areas of audio engineering, record production and telecommunications in the 1990s and 2000s In a digital audio system, an analog electrical signal representing the sound is converted with an analog-to-digital converter (ADC) into a digital signal, typically using pulse-code modulation (PCM). This digital signal can then be recorded, edited, modified, and copied using computer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Audio (song)
"Audio" is a song by pop music group LSD. The song was released on 10 May 2018, and marks the group's second release, following "Genius". Music video The song's music video was directed by Ernest Desumbila. It opens with Diplo purchasing a used BMW 8 Series and finding a fresh LSD tape in the glovebox. As he hits play on "Audio", the clip jumps to a young girl walking home from school, who encounters an animated Sia balloon floating through the air. The girl takes the balloon with her to a sprawling parking lot, where a dance routine breaks out once the "Audio" chorus drops. More psychedelic animations fill the scenery as Diplo speeds through the parched Los Angeles riverbed and Labrinth wanders the otherwise empty city. This song was featured in Fortnite’s Ariana Grande Concert in 2021 Track listing *Digital download #"Audio" (CID Remix) – 2:41 Personnel Credits adapted from Tidal. * Diplo – production, programming * Labrinth – production, engineering, programming * ...

Sound Recording And Reproduction
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Sound recording is the transcription of invisible vibrations in air onto a storage medium such as a phonograph disc. The process is reversed in sound reproduction, and the variations stored on the medium are transformed back into sound waves. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record (in which a stylus cuts grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to ...

Audio (album)
''Audio'' is the debut album by Blue Man Group, released on December 7, 1999, through Virgin Records. The album was nominated for the Grammy Award for Best Pop Instrumental Album. This album was released in two versions: The DVD had 5.1-channel versions of the music in both DVD-Video (using Dolby Digital) and DVD-Audio formats (one on each side) and a CD that had a 2-channel stereo mix of each track. A behind-the-scenes video of the album is viewable on a promotional 2000 VHS known as ''Audio Video''. This video is also included as a bonus on the Audio 5.1 Surround Sound DVD. Reception Heather Phares of Allmusic.com rated ''Audio'' three out of five stars. She explained that it "reflects over a decade's worth of musical and theatrical innovation." Although she stated that "the spectacle of the group playing its sculptural, surreal-looking instruments is absent from the album," she concluded her review by calling it "an album that proves the Blue Man Group is as innovative ...

Stereophonic Audio
Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective. This is usually achieved by using two independent audio channels through a configuration of two loudspeakers (or stereo headphones) in such a way as to create the impression of sound heard from various directions, as in natural hearing. Because the multi-dimensional perspective is the crucial aspect, the term ''stereophonic'' also applies to systems with more than two channels or speakers such as quadraphonic and surround sound. Binaural sound systems are also ''stereophonic''. Stereo sound has been in common use since the 1970s in entertainment media such as broadcast radio, recorded music, television, video cameras, cinema, computer audio, and internet. Etymology The word ''stereophonic'' derives from the Greek (''stereós'', "firm, solid") + (''phōnḗ'', "sound, tone, voice") and it was coined in 1927 by Western Ele ...

Audio Frequency
An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. The generally accepted standard hearing range for humans is 20 to 20,000 Hz. In air at atmospheric pressure, these represent sound waves with wavelengths of to . Frequencies below 20 Hz are generally felt rather than heard, assuming the amplitude of the vibration is great enough. High frequencies are the first to be affected by hearing loss due to age or prolonged exposure to very loud noises. Sound frequencies above 20 kHz are called ultrasonic. Frequencies and descriptions See also *Absolute threshold of hearing *Hypersonic effect, controversial claim for human perception above 20,000 Hz *Loudspeaker *Musical acoustics *Piano key frequencies *Scientific pitch notation *Whistle register The whistle register (also called the flute regi ...

Audio Signal
An audio signal is a representation of sound, typically using either a changing level of electrical voltage for analog signals, or a series of binary numbers for digital signals. Audio signals have frequencies in the audio frequency range of roughly 20 to 20,000 Hz, which corresponds to the lower and upper 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 back into sound. Digital audio systems represent audio signals in a variety of digital formats.Hodgson, Jay (2010). ''Understanding Records'', p.1. . An audio channel or audio track is an audio signal communications channel in a storage device or mixing console, used in operations such as multi-track recording and sound reinforcement.

Semantic Audio
Semantic audio is the extraction of meaning from audio signals. The field of semantic audio is primarily based around the analysis of audio to create some meaningful metadata, which can then be used in a variety of different ways. Semantic Analysis Semantic analysis of audio is performed to reveal some deeper understanding of an audio signal. This typically results in high-level metadata descriptors such as musical chords and tempo, or the identification of the individual speaking, to facilitate content-based management of audio recordings. In recent years, the growth of automatic data analysis techniques has grown considerably, * Music Information Retrieval * Sound recognition * Speech segmentation * Automatic music transcription * Blind source separation * Musical similarity * Audio indexing, hashing, searching * Broadcast Monitoring * Musical performance analysis Applications With the development of applications that use this semantic information to support the user in ident ...
