Audio mixing is used in sound recording, audio editing and sound systems to balance the relative volume and frequency content of a number of sound sources. Typically, these sound sources are the different musical instruments in a band or the sections of an orchestra. Methods and media for sound recording are varied and have undergone significant changes between the first time sound was actually recorded for later playback until now. ... In Music, Audio editing is the process of taking recorded sound and changing it directly on the recording medium. ... Sound system has multiple meanings: A sound reinforcement system is a system for amplifying, reproducing, and sometimes recording audio. ... Amplitude is a nonnegative scalar measure of a waves magnitude of oscillation, that is, magnitude of the maximum disturbance in the medium during one wave cycle. ... Sine waves of various frequencies; the lower waves have higher frequencies than those above. ... A schematic representation of hearing. ... A musical instrument is a device constructed or modified with the purpose of making music. ... In music, a band is a group of musicians, or musical ensemble, usually popular or folk, playing parts of or improvising off of a musical arrangement. ...

Sometimes audio mixing is done live by a sound engineer, for example at rock concerts and other musical performances where a public address system (PA) is used. A typical concert has two mixers, one located in the audience to mix the PA heard by the audience, and the other is located at the side of the stage, mixing for the monitor speakers positioned directly in front of the performers so that they can hear one another. An Audio Engineer is a person recording, editing, manipulating, mixing and mastering sound by technical means. ... Rock and roll (also spelled Rock n Roll, especially in its first decade), also called rock, is a form of popular music, usually featuring vocals (often with vocal harmony), electric guitars and a strong back beat; other instruments, such as the saxophone, are common in some styles. ... A concert is a live performance, usually of music, before an audience. ...

The word monitor is a Latin term for warner or suggester, and now has several different meanings depending on context. ... Closeup of a loudspeaker driver A loudspeaker, or simply speaker, is an electromechanical device which converts an electrical signal into sound. ...

Another example of live mixing is a DJ mixing two records together. Break beats are created by mixing between identical breaks. Often the end of one pre-recorded song is mixed into another so that the transition is seamless, which is done through beat-matching or beat-mixing, and possibly pitch control. For other meanings of DJ, see DJ (disambiguation). ... A break is an instrumental or percussion section or interlude during a song derived from or related to stop-time being a break from the main parts of the song or piece. ... Beatmatching is a mixing technique employed by DJs. ... In music, pitch is the perception of the frequency of a note. ...

At other times, audio mixing is done in studios as part of multitrack recording in order to produce digital or analog audio recordings, or as part of a film or television program. See: remix. Multitrack recording (multitracking or just tracking for short) is a method of sound recording that allows for the separate recording of multiple sound sources to create a cohesive whole. ... Films are produced by recording actual people and objects with cameras, or by creating them using animation techniques and/or special effects. ... A remix is an alternate mix of a song different from the original version, made using the techniques of audio editing. ...

An audio mixing console, or mixing desk, has numerous rotating controls (potentiometers) and sliding switches (faders) that are used to manipulate the volume, the addition of effects such as reverb, and frequency content (equalization) of audio signals. On most consoles, all the controls that apply to a single channel of audio are arranged in a vertical column called a channel strip. Larger and more complex consoles such as those used in film and television production can contain hundreds of channel strips. Many consoles today, regardless of cost, have automation capabilities so the movement of their controls is performed automatically, not unlike a player piano. A recent trend is to use a "control surface" connected to a computer. This eliminates much of the electronics in a conventional console.

Audio mixing on a personal computer is also gaining momentum. More and more independent artists are starting to use their personal computers for digital recording and mixing their work. Audio editing on the computer is also easy and generally preferred. A drawing of the everyday computer. ... In digital recording, the analog signal of a motion-picture/sound is converted into a stream of discrete numbers, representing the changes in air pressure (chroma and luminace values in case of video) through time; thus making an abstract template for the original sound. ... Audio mixing is used in sound recording, audio editing and sound systems to balance the relative volume and frequency content of a number of sound sources. ... In Music, Audio editing is the process of taking recorded sound and changing it directly on the recording medium. ...

A recent trend is mixing to 5.1, which is "surround" audio. This requires 6 channels of audio: left, center, right, left rear, right rear, and low frequencies. In commercial release, only DVD video has a standard. So far there has been little demand for 5.1 in the audio and music domain, but it seems destined that one of the several commercial formats will ascend.
