UNIT 17: AUDIO PRODUCTION

Effects unit (Definitions from Wikipedia)

EFFECT Reverberations:

Reverberation is the persistence of sound in a particular space after the original sound is removed.

REVERBERATION EXAMPLE

EFFECT Distortions:

A distortion is the alteration of the original shape (or other characteristic) of an object, image, sound, waveform or other form of information or representation.

DISTORTION EXAMPLE

EFFECT Talk box:

A talk box is an effects unit that allows a musician to modify the sound of a musical instrument.

The musician controls the modification by lip syncing, or by changing the shape of their mouth.

TALK BOX EXAMPLE

EFFECT Pitch bender:

Portamento is a a vocal slide between two pitches and its emulation by members of the violin family and certain wind instruments, and is sometimes used interchangeably with anticipation.

PITCH BENDING EXAMPLE

EFFECT Delay:

Delay is an audio effect which records an input signal to an audio storage medium, and then plays it back after a period of time.

The delayed signal may either be played back multiple times, or played back into the recording again, to create the sound of a repeating, decaying echo.

EFFECT Chorus:

In music, a chorus is when an individual plays/ sings at the same pitch converge and are perceived as one. While similar sounds coming from multiple sources can occur naturally

CHORUS EXAMPLE

EFFECT

Autotune: Auto-Tune uses a phase vocoder to correct pitch

in vocal and instrumental performances. It is used to disguise off-key inaccuracies and mistakes, and has allowed singers to perform apparently perfectly tuned vocal tracks without needing to sing in tune.

AUTOTUNE EXAMPLE

EFFECT Tremelo:

Tremolo, or tremolando, is a musical term that describes various trembling effects, falling roughly into two types. The first is a rapid reiteration Of a single note, particularly used on bowed string

instruments and plucked strings such as harp, where it is called whispering.

Between two notes or chords in alternation, an imitation (not to be confused with a trill) of the preceding that is more common on keyboard instruments. Mallet instruments such as the marimba are capable of either method.

A roll on any percussion instrument, whether tuned or untuned.

TREMELO EXAMPLE

EFFECT Vibrato:

Vibrato is a musical effect consisting of a regular, pulsating change of pitch. It is used to add expression to vocal and instrumental music. Vibrato is typically characterised in terms of two factors: the amount of pitch variation and the speed with which the pitch is varied.

VIBRATO EXAMPLE

EFFECT Gating:

Gating is used in sound engineering with oscilloscopes, analog signal processing and more specifically audio signal processing.

EFFECT Limiter:

In electronics, a limiter is a circuit that allows signals below a specified input power to pass unaffected while attenuating the peaks of stronger signals that exceed this input power.

EFFECT Surround sound:

Surround sound encompasses a range of techniques such as for enriching the sound reproduction quality of an audio source with audio channels reproduced via additional, discrete speakers.

SURROUND SOUND EXAMPLE

EFFECT Mono:

Mono sound, which uses a single channel, as opposed to stereophonic (or stereo) sound.

EFFECT Stereo:

The term Stereophonic, commonly called stereo, sound refers to any method of sound reproduction in which an attempt is made to create an illusion of directionality and audible perspective.

STEREO EFFECT
