All vibration that falls between the frequency range of 20 to 20K Hz, and therefore detectable to the human ear. Often used in recording to mean the desired sound of the recording as apposed to undesired noise.
Traditionally, audio signals were recorded and played back as analog signals. In today's computer circles, audio refers to files of digital (binary) codes that are produced by converting analog signals to digital audio. The quality of digital audio depends on the sampling rate and the sample size. Humans hear dound in the range of 15 to 20,000 Hz.
Audio refers to sound. Sound is actually waves of air pressure that strike our eardrums and cause them to vibrate. Optimally, the human ear is capable of discerning frequencies within the 20Hz to 20,000Hz range. Typically, most adults over 30 have about a 40Hz to 17,000Hz range. The main task of an audio system is to transform electrical signals into air pressure waves that are as close as possible to the originally recorded sound.
In video communications, electrical signals that carry sounds. The term is also used to describe systems concerned with sound recording and transmission, such as speech pickup systems, transmission links that carry sounds and amplifiers etc.

The term “Audio” shall mean recorded audio used in connection with the Customer Web Page, including (without limitation) spoken words, narration, sounds, music, lyrics, noises, sound effects and sound recordings.
In video communications, electrical signals that carry sounds. The term is also used to describe systems concerned with sound with recording and transmission; speech pickup systems, transmission links that carry sounds, amplifiers and the like.
A term used to describe sounds within the range of human hearing. Also used to describe devices which are designed to operate within this range. Auxiliary Bass Radiator: A loudspeaker drive unit fitted to a box loudspeaker, coupled acoustically but not electrically to the input signal. Functions somewhat like a port or tuned tube in the loudspeaker cabinet supplementing bass output and aiding loudspeaker sensitivity.
Audio refers to sound. Audio can be facilitated by the use of telephone and radio communication. Various software programs and services exist which allow telephone communication via computers connected to the Internet. Multimedia presentations can also feature audio.
relating to sound--or frequencies--that can be heard by the human ear; the audible frequency range extends from approximately 20 Hz to 20,000 Hz; the human voice extends over a frequency range of about 100 Hz to 3,000 Hz.
Most cameras capture 'video' only (what you can see) - some come with audio too (sound). You can add a microphone to a security system to capture audio if needed. To record the sound, your recording device needs to support audio (must have at least one audio input).
Sound. Computers (and audio compact discs and digital audio tape) handle sound by storing a sequence of discrete samples. The continuous sound waveform from the original source is sampled tens of thousands of times a second. Each sample represents the intensity of the sound pressure wave at that instant. Apart from the sampling frequency, the other parameter is the digital encoding of each sample including the number of bits used. The encoding may be linear, logarithmic or mu-law. The source could be a piece of music, voice recording, or generated audio. See also mu-law or u-law.
This term relates to the reproduction of sound, especially to the sound part of a telecast as opposed to the video (picture) portion.
In contrast to the Stereo sound system and conventional Surround Systems, this sound system offers five separate full band audio signals: Left, middle, right, rear left, rear right. An additional subwoofer (LFE) channel is also provided.
Relating to frequencies that can be heard by the human ear. Approximately 20 Hz. to 20 kHz. Related Terms: AF | intermediate frequency amplifier | modulation | moving coil loudspeaker | power amplifier | speaker | volume | woofer
Codec An IC and related circuitry which encodes and decodes complex waveforms, such as music and voice. Such waveforms can be stored directly, but would take up many times as much storage as waveforms compressed by a codec.
