Compose With Sounds

Additive Synthesis

A process of creating sounds in which complex sounds are made from the combination of simpler elements (such as sine waves). Different types of simple sounds can be combined to create ever more complex sound textures.

Amplitude Modulation (AM)

A type of manipulation in which one input signal modulates the amplitude of another sound.

Balancing sounds

Balancing is a term used to describe the management of sound levels and panning in a final mix. The achievement of a well-balanced mix will make sure that all the sounds fit together, that no one sound is so quiet that it can’t be heard, and that no one sound is too loud and overpower others. Balancing will ensure that the final piece is not overly weighted to either the left or the right (in Stereo), and that sounds are spread evenly through the stereo space.

Band-pass Filter

The Band Pass Filter will only allow one band of sound to pass through.

Read more

Band-reject Filter

The Band Reject Filter will not let a certain band of sound to pass through

Read more

Chorus

The use of multi-layering one or more sounds, often with the use of very small-scale delays. The chorusing effect leads to the impression of a duplication of the original input sound, a chorus consisting of an ensemble of the input sound(s).

Collage

An artwork in which small fragments are cut and pasted together to make a larger final work. In sound-based music this may concern extremely brief elements of sound material up to musical fragments. [EARS]

Delay

A process in which an input signal is looped and repeated.

Digital

Read more

Distortion

A process by which the tops of a soundwave are sliced off, converting the smooth wave into a more jagged shape.

Read more

DSP (Digital Signal Processing)

A term that describes the digital manuiplation of (audio) signals.

Read more

Editing

The process of selection, cutting, layering and ordering through which elements are combined and polished in the creation of a final work.

Read more

Equalisation

A process by which the various frequency energies of sounds can be balanced, usually using a series of band filters to boost or cut certain portions of the sound.

Read more

Fade

A change of volume over time, usually moving from or too silence (fade-in or fade-out).

Read more

FFT (Fast Fourier Transform)

A method which allows the visualisation of a sounds energy distribution over time.

Read more

Filter

A filter changes the frequency makeup of a sound by making parts of it weaker. Filters allow you to focus on parts of a sound that are of interest to you, or to take away parts that you don’t like.

Read more

Flanging

An effect that uses very short delays (in ms) to create a cancellation effect when a delayed copy of a sound is added to the original audio stream

Read more

FM (Frequency Modulation)

FM (Frequency Modulation) Involves one frequency affecting another. FM can be applied as an effect or used as a form of synthesis.

Read more

Gain

Gain is a measure of how loudly the sound plays back. You can change gain, just like you can turn the volume up or down on your TV or stereo.

Read more

Granular Synthesis

A method by which sounds are broken into tiny grains and then reassembled and reorganised to form other sounds.

Read more

Harmoniser

A manipulation in which several versions of an input sound of identical [ears2_encyclopaedia_entry_link id="183"]Duration[/ears2_encyclopaedia_entry_link] (in [ears2_encyclopaedia_entry_link id="241"]Phase[/ears2_encyclopaedia_entry_link]) are created at specifically chosen pitches.

Read more

High-pass filter

A high-pass filter lets the high frequencies through and removes the low.

Read more

Layering

A compositional approach in which different sound textures are placed alongside one another.

Read more

LFO (Low Frequency Oscillator)

A sound wave that has a low frequency (usually below the range of human hearing) but which can be used to manipulate sound within the range of human hearing.

Read more

Loop

To loop a sound is to continuously repeat it.

Read more

Low-pass Filter

A low-pass filter lets the bass tones through (the low frequencies) and removes the treble (high frequencies)

Read more

Manipulation (effect)

A process by which sounds are changed or transformed. There are many manipulations available within the CwS software. Manipulations are sometimes referred to as ‘effects’.

Read more

Panning

The placement of sounds left and right between a stereo pair of speakers.

Read more

Pitch Shifting

This refers to the changing of the pitch in either direction. Traditionally pitch shifting went hand in hand with the change of speed of a tape recorder.
