Transcript

  • 1. UNIT 17: AUDIOPRODUCTIONEffects unit (Definitions from Wikipedia)
  • 2. EFFECT Reverberations:  Reverberation is the persistence of sound in a particular space after the original sound is removed.
  • 3. REVERBERATION EXAMPLE
  • 4. 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.
  • 5. DISTORTION EXAMPLE
  • 6. 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.
  • 7. TALK BOX EXAMPLE
  • 8. 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.
  • 9. PITCH BENDING EXAMPLE
  • 10. 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.
  • 11. 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
  • 12. CHORUS EXAMPLE
  • 13. 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.
  • 14. AUTOTUNE EXAMPLE
  • 15. 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.
  • 16. TREMELO EXAMPLE
  • 17. 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.
  • 18. VIBRATO EXAMPLE
  • 19. EFFECT Gating:  Gating is used in sound engineering with oscilloscopes, analog signal processing and more specifically audio signal processing.
  • 20. 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.
  • 21. 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.
  • 22. SURROUND SOUND EXAMPLE
  • 23. EFFECT Mono:  Mono sound, which uses a single channel, as opposed to stereophonic (or stereo) sound.
  • 24. 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.
  • 25. STEREO EFFECT
