Audio effects

  1. 1. A U D I O E F F E C T S
  2. 2. A U T O - T U N ECreated by Antares Audio Technologies Auto-Tune uses a phase vocoder to correct pitch in vocal and instrumental performances. Auto-tune has the ability to disguise off-key notes and mistakes allowing singers to create a false illusion, that their singing well and in tune
  3. 3. This effect is one lately commonly used in the hip-hop industry by rappers and MCs such as Kanye West, Lil Wayne and T-pain, for the main reason that it gives an interesting twist to their one-tone vocals in their music
  4. 4. AUDIO COMPRESSIONThe Basic idea of audio compression is to lower the louder parts of the song to decrees the dynamics, this then makes to parts of the song that are too harsh sound softer, and the parts that were too low more audible.
  5. 5. Compression is used in the following example.
  6. 6. D E L A YThe delay sound effect records an input signal to an audio storage medium, then it plays it back after a period of time. It can create the sound of a repeating echo, by either playing your recorded sound back multiple times, or played back into the recording again.
  7. 7. Delay is used in the song by U2, you can here it in the guitar. Its properly most famous in this song.
  8. 8. D I S T O R T I O N In order to create a dirty, fussy, hardpounding sound to your audio, you would properly use distortion. The distortion sound effect does this compressing the peaks of a musical instruments sound wave and adding overtones.
  9. 9. Though The Beatles did not invent distortion, they did bring it to the masses in their song ‘Revolution’ taken from the album White Album. This effect is most commonly used in the genres of Pop, Rock and Metal. But it is also used in some hip-hop songs as recognised in rapper ‘Drakes’ song ‘Karaoke’
  10. 10. G A T E (N O I S E) an extreme form of expansion noisegating is. Signals below a certain point are either heavily weakened oreliminated completely. This leaves only higher level signals and removes background noise when the signal is not present.
  11. 11. Phil Collins is a good example of noisegating in his hit single ‘In The Air Tonight’,the noise gating in this song is best heard on in the drums.
  12. 12. E Q U A L I Z A T I O NWhen your boosting or reducing the levels of various frequencies in a signal you are using the sound effect of Equalization. For Example, equalization can mean turning the bass/treble controls up or down.
  13. 13. An Equalizer is used in the following examples.
  14. 14. C H O R U SThe chorus effect is designed to make a signal sound like it was produced by multiple similar sources. For example, if you add the chorus effect to a solo singers voice, the results sounds like a chorus.
  15. 15. Chorus is one of the most common effects and is used in mostly all genres, it is most evident in the following examples.
  16. 16. P H A S E RPhasing is a sweeping/whooshing effect often used in music. The effect is created by mixing the original signal with another version of itself which has been phase-shifted.
  17. 17. This results in various out-of-phase interactions over time which gives the sweeping effect used in this example of‘Voices’ by Disturbed but only in the intro.
  18. 18. T A L K B O XA 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.
  19. 19. The most famous example of the talk box comes from one of Bon Jovi’s famous hits‘Living On A Prayer’, where the talk box is used in the intro
  20. 20. S U R R O U N D S O U N D Surround sound takes in a range of techniques (such as for enrichingthe sound duplicated quality of an audio source with audio channels reproduce by additional speakers. .
