Shelving filters are used as common tone controls (bass and treble) found in consumer audio equipment such as home stereos, and on guitar amplifiers and bass amplifiers. These implement a first-order response and provide an adjustable boost or cut to frequencies above or below a certain point.
As shown in the bass management block diagram, a 5.1-channel audio system consists of five discrete, full-range main channels (front left, center, front right, surround left, and surround right), plus a band-limited low-frequency effects (LFE) channel for added bass (this corresponds to the .1).
Tone control is a type of equalization used to make specific pitches or frequencies in an audio signal softer or louder. It allows a listener to adjust the tone of the sound produced by an audio system to their liking, for example to compensate for inadequate bass response of loudspeakers or earphones, tonal qualities of the room, or hearing impairment.
Smiley face curves have been popular with some car audio enthusiasts, disc jockeys, electric bass players, home stereo owners and sound reinforcement operators. [ 2 ] [ 3 ] Though the graphic equalizer was intended to tailor a system's response to compensate for venue and performance conditions, the smiley face curve is sometimes applied as a ...
Presets stored settings for the amount of each kind of processing to be applied: automatic gain control, limiting, bass boost, etc. Presets cannot be added. The Volume Logic plug-in incorporated multi-band dynamics processing technology, solving common audio problems such as speaker distortion and volume shifting. [citation needed]
The proximity effect in audio is an increase in bass or low frequency response when a sound source is close to a directional or cardioid microphone. [1] [2] Proximity effect is a change in the frequency response of a directional pattern microphone that results in an emphasis on lower frequencies. It is caused by the use of ports to create ...

5.1 surround sound ("five-point one") is the common name for surround sound audio systems. 5.1 is the most commonly used layout in home theatres. [1] It uses five full-bandwidth channels and one low-frequency effects channel (the "point one"). [ 2 ]
