Introduction

• Applying a process to change a sound form• Commercial uses– Music– Films– Advertising– Games

• Approach– Describe main effects– Give some examples

Sound effects in this presentation

• Distortion• Talk box• Pitch bend• Delay and multi tap delay• Auto tune• Phaser• Temeblo

Distortiona) what is it?

Creates a “warm”, “dirty” and fuzzy sound by compressing the peaks of sound waves and adding overtones.

The picture shows a "Turbo Distortion" guitar effect pedal made by Bo which distorts the sound made by the guitar into a different tone of sounds when you press down on the pedal

Distortionb) Examples

Jimi HendrixExplanation of distortion including audio examples

Talk Boxa) what is it?

• 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.

• This picture shows a modern day talk box on its own and a talk box being used.

Talk Boxb) Examples

Guitar talk box Peter Frampton

Pitch Benda) What is it?

• A smooth uninterrupted glide in passing from one tone to another, especially with the voice or a bowed stringed instrument.

• This electric keyboard contains a pitch bend wheel which changes the pitch much like the way a guitarist bends a string or uses a whammy bar.

Pitch Bendb) Examples

Pitch bend music example

Delay and Multitap delaya) What is it?

• 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. Multitap 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.

• Here is a picture of a Mac programme that you can use to change the Delay and Multitap delay of an audio file.

Delay and Multitap delayb) Examples

Multi-tap delay in reason 3

Auto tunea) What is it?

• Auto-Tune is a proprietary audio processor created by Antares Audio Technologies. 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.

• The first picture shows a programme that auto tunes peoples vocals. The second picture shows the X- Factor, if you want a great a example of auto tuning then switch on to X- Factor on Saturday night.

Auto tuneb) Examples

Youtube user makes a song by using words from different videos on the internet. This is a great example of auto tune but is also an example of talk box

Phasera) What is it?

• A phaser is an audio signal processing technique used to filter a signal by creating a series of peaks and troughs in the frequency spectrum. The position of the peaks and troughs is typically modulated so that they vary over time, creating a sweeping effect. For this purpose, phasers usually include a low-frequency oscillator.

• Phasing is a popular effect for electric guitar. The picture shows a Phaser box that would be used with a guitar .

Temebloa) What is it?

• An imitative sound, as of thunder or an explosion, produced artificially for theatrical purposes, as for a film, play, or radio program. Often used in the plural.

• Sound effects are the most commonly used kind of effect in my opinion. You hear them in films, T.V, Games, radios, songs, advertisements etc…

Temeblob) Examples

• This video is a great example of the Temeblo effect.

• This video shows a group of people making the sound of rain and thunder
