* aac – the Advanced Audio Coding format is based on the MPEG2 and MPEG4 standards.

Audio signal processing, sometimes referred to as audio processing, is the intentional alteration of auditory signals, or sound, often through an audio effect or effects unit.

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

Audio unprocessed by reverb and delay is metaphorically referred to as " dry ", while processed audio is referred to as " wet ".

Audio is an electrical or other representation of sound.

Audio CD is an umbrella term that refers to many standards of means of playing back audio on a CD.

Audio and video encoded with many codecs might be put into an AVI container, although AVI is not an ISO standard.

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.

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 latency is the delay between when an audio signal enters and when it emerges from a system.

Timestamping is built into FireWire MIDI interfaces and Mac OS X Core Audio.

The Open Sound Control ( OSC ) protocol was developed at the Center for New Music and Audio Technologies ( CNMAT ) of the University of California, Berkely, and is supported by software programs such as Reaktor, Max / MSP and Csound, and some newer hardware controllers, including the Lemur Input Device.

MPEG-3 is not to be confused with MP3, which is MPEG-1 Audio Layer III.

MPEG-2 Audio is defined in ISO / IEC 13818-3

AAC is more efficient than the previous MPEG audio standards, and is in some ways less complicated than its predecessor, MPEG-1 Audio, Layer 3, in that it does not have the hybrid filter bank.

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

The first Philips CD-i player, released in 1991 and initially priced around USD $ 700, is capable of playing interactive CD-i discs, Audio CDs, CD + G ( CD + Graphics ), Karaoke CDs, and Video CDs ( VCDs ), though the last requires an optional " Digital Video Card " to provide MPEG-1 decoding.

* Steganophony-the concealment of messages in Voice-over-IP conversations, e. g. the employment of delayed or corrupted packets that would normally be ignored by the receiver ( this method is called LACK-Lost Audio Packets Steganography ), or, alternatively, hiding information in unused header fields.

Audio recordings use native speakers, and one strength is helping learners improve their accent.

Audio is available for this text with a native speaker from Milan ( compare to the same text in Italian ).

Although there was native support for many popular games which used middleware sound libraries like HMI Sound Operating System, the Miles Audio Interface Libraries ( AIL ), the Miles Sound System and others, the user had to patch the games by replacing the existing sound drivers with the UltraSound versions provided on the installation CD.

* Audio formats: Vorbis, AAC, AAC +, M4A, MP3, AMR-NB, AMR-WB, RealAudio, WMA, a-law, u-law and audio containers AIFF, WAV, AU

Audio Interchange File Format ( AIFF ) is an audio file format standard used for storing sound data for personal computers and other electronic audio devices.

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.

* Audio formats supported natively: MP1, MP2, MP3, MPC, AAC, Ogg Vorbis, FLAC / Ogg FLAC, ALAC, WavPack, WAV, AIFF, AU, SND, CD, Opus

** Audio formats: MIDI, AIFF, WAV / WAVE, AIFF, MP2, MP3, AAC, AACplus ( AAC +), Vorbis, AC3, DTS, ALAC, AMR, FLAC, Monkey's Audio ( APE ), RealAudio, SHN, WavPack, MPC / Musepack / Mpeg +, Shorten, Speex, WMA, IT, S3M, MOD ( Amiga Module ), XM, NSF ( NES Sound Format ), SPC ( SNES ), GYM ( Genesis ), SID ( Commodore 64 ), Adlib, YM ( Atari ST ), ADPCM ( Nintendo GameCube ), and CDDA.

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.

To record WAV files to an Audio CD the file headers must be stripped and the remaining PCM data written directly to the disc as individual tracks with zero-padding added to match the CD's sector size.

The default file formats are Windows Media Video ( WMV ), Windows Media Audio ( WMA ), and Advanced Systems Format ( ASF ), and its own XML based playlist format called Windows Playlist ( WPL ).

Audio data compression techniques, such as MP3, Advanced Audio Coding, Ogg Vorbis, or FLAC, are commonly employed to reduce the file size.

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 ).

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.

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 ).

In November 2003, Johansen released QTFairUse, an open source program which dumps the raw output of a QuickTime Advanced Audio Coding ( AAC ) stream to a file, which could bypass the Digital Rights Management ( DRM ) software used to encrypt content of music from media such as those distributed by the iTunes Music Store, Apple Computer's online music store.
