This document summarizes various audio effects used in music, films, advertising and games. It describes effects such as distortion, talk box, pitch bend, delay, auto-tune, phaser and temeblo. For each effect there is a brief explanation of what it is and how it works, along with examples of its use. Pictures and audio examples are provided to illustrate several of the effects.

2. • Applying a process to change a sound form
• Commercial uses
– Music
– Films
– Advertising
– Games
• Approach
– Describe main effects
– Give some examples

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

4. 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

6. • 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.

8. • 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.

9. Pitch bend music
example

10. • 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.

12. • 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.

13. 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

14. • 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 .

15. Phaser effect being used
in song

16. • 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…

17. • This video is a great
example of the Temeblo
effect.
• This video shows a
group of people making
the sound of rain and
thunder
