Audio processing was necessary for early radio broadcasting, as there were many problems with studio to transmitter links.

Audio broadcasting ( be it for television or audio broadcasting ) is perhaps the biggest market segment ( and user area ) for audio processing products — globally.

MPEG-1 Audio Layer 2 encoding was derived from the MUSICAM ( Masking pattern adapted Universal Subband Integrated Coding And Multiplexing ) audio codec, developed by Centre commun d ' études de télévision et télécommunications ( CCETT ), Philips, and Institut für Rundfunktechnik ( IRT ) in 1989 as part of the EUREKA 147 pan-European inter-governmental research and development initiative for the development of a system for the broadcasting of audio and data to fixed, portable or mobile receivers ( established in 1987 ).

While most other countries abandoned VHF due to its poor suitability for TV broadcasting and allocation for Digital Audio Broadcasting, the FCC chose to cut high-UHF channels instead, because frequency-use rights could be auctioned for a greater price.

In 1985, TV station WGBH, the Boston, Massachusetts, member of the Public Broadcasting Service ( PBS ), began investigating uses for the new technology of stereophonic television broadcasting, particularly multichannel television sound ( MTS ), which allowed for a third audio channel, called the Secondary Audio Program ( SAP ).

Online broadcasting in Windows Media Video / Windows Media Audio of 3 channels.

B. Robinson Music Library ; Mixon Hall, a 250-seat, state-of-the-art recital hall that also includes the Robert and Jean Conrad Audio Control Room for high-tech broadcasting ; the Fred A. Lennon Education Building which includes new practice rooms, teaching studios and a student lounge ; Kulas Center for International Education ( Distance Learning Studio ) and administrative space.

Audio may also refer to:

Audio and radio signals carried on electrical wires are also examples of alternating current.

Most, if not all, of the authors in the JSAC edition were also active in the MPEG-1 Audio committee.

However, the sound quality falls short of the standards common with SACDs ( Super Audio CD ) and also that of audiophile CDs from companies such as Mobile Fidelity Sound Lab.

MPEG-2 part 3 also defined additional bit rates and sample rates for MPEG-1 Audio Layer I, II and III.

Advanced Audio is also defined in Part 3 of the MPEG-4 standard.

The system can also play Audio CDs.

** Grooves ( See also Audio Data )

An all new lossless DTS-HD Master Audio 5. 1 soundtrack was also made from the original stereo recordings by Scorsese's personal sound team.

Waveform Audio File Format ( WAVE, or more commonly known as WAV due to its filename extension ), ( also, but rarely, named, Audio for Windows ) is a Microsoft and IBM audio file format standard for storing an audio bitstream on PCs.

Audio Video Interleaved ( also Audio Video Interleave ), known by its initials AVI, is a multimedia container format introduced by Microsoft in November 1992 as part of its Video for Windows technology.

Audio and radio signals carried on electrical wires are also examples of alternating current.

* Eureka 147, also known as the Digital Audio Broadcasting ( DAB ) system

Apple has also created another recent extension to the AIFF format in the form of Apple Loops used by GarageBand and Logic Audio, which allows the inclusion of data for pitch and tempo shifting by an application in the more common variety, and MIDI-sequence data and references to GarageBand playback instruments in another variety.

The graphics tablet are also used for Audio Haptic products where blind or visually impaired people touch swelled graphics on a graphic tablet and get audio feedback from that.

Audio recordings of 1973 – 1974 Guiding Light episodes have also been uploaded.

Big Audio Dynamite also referenced it in their 1986 song " Sightsee M. C!

In August 1995 ForeFront Records released One Way: Songs of Larry Norman, a tribute album that included covers of 14 Norman's classic songs by ForeFront artists, including dc Talk ; Audio Adrenaline, Grammatrain ; and Rebecca St. James, whose father, David Smallbone, booked and promoted Norman's first concerts and distributed Norman's early records in Australia, including his eponymous 1977 album, ( which is also known as Starstorm ).

The Super Audio CD ( SACD ) format was created by Sony and Philips, who were also the developers of the earlier standard audio CD format.

The term MP2 and filename extension < tt >. mp2 </ tt > usually refer MPEG-1 Audio Layer II data, but can also refer to MPEG-2 Audio Layer II, a mostly backwards compatible extension which adds support for multichannel audio variable bit rate encoding, and additional sampling rates, defined in ISO / IEC 13818-3.

Internally, BBC Radio is now organised under the banner of BBC Audio & Music, which also oversees online audio content.

* Audio: 500 Hz, 1 kHz, and 1. 5 kHz tones ( can be modulated quickly to produce different tones )

* A multiple Sequencer which can mix MIDI tracks with Digital Audio ;

When the music is stored in an audio file format that is lossless such as FLAC, Monkey's Audio or WMA Lossless, the computer playback of recorded audio can serve as an audiophile-quality source for a hi-fi system.

* Audio can often be compressed at 10: 1 with imperceptible loss of quality

Audio effects units that are frequently used in stage and recording, such as reverbs, delays and choruses, can be remotely adjusted via MIDI signals.

* Audio: 3 square wave generators, 1 noise generator, the system has a mono speaker, but stereo sound can be had via headphone output

Audio can be propagated by modulated ultrasound.

Audio CDs can be ripped as WMA or WMA 10 Pro ( WMA 10 Pro in WMP 11 and later ) at 48, 64, 96, 128, 160 and 192 kbit / s, WMA lossless ( 470 to 940 kbit / s ) ( 9 Series on XP and later ), WMA variable bitrate ( from 40-75 kbit / s up to 240-355 kbit / s ), MP3 at 128, 192, 256 and 320 kbit / s, or uncompressed WAV ( WAV ripping in WMP 11 and later ).

Audio can be ripped using error correction and ripped audio can be protected with Windows Media DRM.

Audio can be stored in either of two forms: 16-bit Linear PCM stereo at 48 kHz sampling rate ( 768 kbit / s per channel, 1. 5 Mbit / s stereo ), or four nonlinear 12-bit PCM channels at 32 kHz sampling rate ( 384 kbit / s per channel, 1. 5 MBit / s for four channels ).

DIF blocks are the basic units of DV streams and can be stored as computer files in raw form or wrapped in such file formats as Audio Video Interleave ( AVI ), QuickTime ( QT ) and Material Exchange Format ( MXF ).

DV Audio / Video data can be stored as raw DV data stream file ( data is written to a file as the data is received over FireWire, file extensions are. dv and. dif ) or the DV data can be packed into container files ( ex: Microsoft AVI, Apple MOV ).

Audio drama, whether newly produced or OTR classics, can be found on CDs, cassette tapes, podcasts, webcasts and conventional broadcast radio.

Audio quality differences between CD audio and MP3 can be noticeable.

Miniature binaural " in-ear " or " near-ear " microphones can be linked to a portable Digital Audio Tape ( DAT ) or MiniDisc recorder, bypassing the need for a dummy head by using the recordist's own head.

A digital recording ( such as a CD ) encoded to the Monkey's Audio format can be decompressed into an identical copy of the original audio data.

Because Monkey's Audio is relatively slow when encoding or decoding files ( what FLAC accomplishes in several seconds can take a minute or more with Monkey's Audio ) FLAC has largely eclipsed it as the preferred format for commercial distribution of lossless audio.

Monkey's Audio files can be encoded and decoded on any platform which has a J2SE implementation, by the means of the unofficial JMAC library, which is Free software licensed under the GNU LGPL.
