11. Sound Effects

Sound Effects Categories

Sounds Effects can be defined as any element of a track that falls outside the classification of drums, percussion or musical instrument.    Sound Effects can be used in 2 main was, either as atmospheric, i.e. set the mood / convey an emotion or as a rhythmic component.

A few examples of DSP sound effects include atmospheric noise, swoosh wind sounds, and zaps.  The addition of sound effects give a song character and can be used either subtly or dramatically.

 

Creating Digital Sound Effects
Most sample libraries come with a range of sound effects.  However, if you’ve created your own Synth sounds from scratch, you have the additional satisfaction of guaranteeing originality.

Electronic sound effects can be generated by manipulating white noise or tones with filters.  Most Synthesisers and VST have the ability to generate noise, and add their own particular character with onboard effects.

As with Synthesiser instruments, the best way to understand how to generate sounds is to play around with the presets.

Adding Filters

  • By adding distortion, thin noise presents can be thickened.
  • Filter the noise through a vocoder to add harmonic components.
  • Add noise through modulation, e.g. Phaser, Flanger etc to create an element of motion.

Swoosh = noise VCO = BP cut off modulated to LFO Sine

Creating Sound Effects from Analogue Sources

Sound Effects from an Analogue Source are infinite.  A few examples are listed below.
