Sonic Art & Sound Design- P35:Sonic art is a new art form, or rather, forms. As we shall see, it can encompass a wide range of activities, perhaps wider than almost any other art form. It is an unusual case, based upon a medium that has traditionally been regarded as inferior and subservient to other creative or expressive forms. | CONCLUSION Glossary Acousmatic A sound that has no apparent visual origin or that is heard in isolation from its source. Acoustics The qualities of a space that by modifying a sound have an impact upon its qualities or the way in which it is experienced. A D converter The electronic means whereby an audio signal is converted into digital form and vice versa . Algorithm A formula or a closely defined procedure. Specialist algorithms can be used to create and transform sound within computers. An algorithm applies a particular usually numerical process to incoming data resulting in that data being changed in a more-or-less predictable fashion. Convolution 1 The recreation of the acoustic qualities of a space. 2 The merging of two different sounds using a computer. Delay The insertion of a time lag before a sound is re-heard. Usually achieved by means of a digital delay line. Diffusion 1 The way in which different frequencies are affected by acoustic or reverberant factors. 2 A practice characteristic of electroacoustic performance using multiple loudspeakers. Dynamics The qualities of a sound that are defined by its volume at a given instant or instants. Echo A sound repeatedly delayed and replayed typically with each repeat quieter than the one before. Envelope The overall dynamic qualities of a sound - normally defined in terms of attack decay sustain release. Environment Artwork that seeks to modulate the immediate surroundings by means of sound and or visual projections rather than by the display of specific objects. Feedback Connecting the output of a process back to the input either in order to be reprocessed or to apply a controlling influence. Filter An electronic device that can selectively control the level of different frequency components of a sound. Granulation The manipulation of sound whereby the sound is not directly created from scratch nor is an existing sound sampled in the normal sense of the word. Instead an existing sound is dissected into very .
