History

The Sound and Music Computing research field can be traced back to the 1950s, when a few experimental composers, together with some engineers and scientists, independently and in different parts of the world, began exploring the use of the new digital technologies for music applications. Since then the SMC research field has had a fruitful history and different terms have been used to identify it. Computer Music

Subfields

The current SMC research field can be grouped into a number of subfields that focus on specific aspects of the sound and music communication chain.
  • Processing of sound and music signals: This subfield focuses on audio signal processing
    Audio signal processing
    Audio signal processing, sometimes referred to as audio processing, is the intentional alteration of auditory signals, or sound. As audio signals may be electronically represented in either digital or analog format, signal processing may occur in either domain...

     techniques for the analysis, transformation and resynthesis of sound and music signals.

  • Understanding and modeling sound and music: This subfield focuses on understanding and modeling sound and music using computational approaches. Here we can include Computational musicology
    Computational musicology
    Computational musicology is defined as the study of music with computational modelling and simulation. It saw its beginning in the 1950s and originally did not utilize computers, but more of statistical and mathematical methods...

Areas of Application

SMC research is a field driven by applications. Examples of applications are:
  • Digital music instruments: This application focuses on musical sound generation and processing devices. It encompasses simulation of traditional instruments, transformation of sound in recording studios or at live performances and musical interfaces for augmented or collaborative instruments.

  • Music production: This application domain focuses on technologies and tools for music composition. Applications range from music modeling and generation to tools for music post–production and audio editing.

  • Music information retrieval: This application domain focuses on retrieval technologies for music (both audio and symbolic data). Applications range from music audio–identification and broadcast monitoring to higher–level semantic descriptions and all associated tools for search and retrieval.

  • Digital music libraries: This application places particular emphasis on preservation, conservation and archiving and the integration of musical audio content and meta–data descriptions, with a focus on flexible access. Applications range from large distributed libraries to mobile access platforms.

  • Interactive multimedia systems: These are for use in everyday appliances and in artistic and entertainment applications. They aim to facilitate music–related human–machine interaction involving various modalities of action and perception (e.g. auditory, visual, olfactory, tactile, haptic, and all kinds of body movements) which can be captured through the use of audio/visual, kinematic and bioparametric (skin conduction, temperature) devices.

  • Auditory interfaces: These include all applications where non–verbal sound is employed in the communication channel between the user and the computing device. Auditory displays are used in applications and objects that require monitoring of some type of information. Sonification
    Sonification
    Sonification, a form of auditory display, is the use of non-speech audio to convey information or perceptualize data. Auditory perception has high temporal and pressure resolution, which opens up possibilities for it as an alternative or complement to visualization techniques.For example, the...

     is used as a method for data display in a wide range of application domains where auditory inspection, analysis and summarisation can be more efficient than traditional visual display. Sonic interaction design
    Sonic interaction design
    Sonic interaction design is the study and exploitation of sound as one of the principal channels conveying information, meaning, and aesthetic/emotional qualities in interactive contexts. Sonic interaction design is at the intersection of interaction design and sound and music computing...

    emphasizes the role of sound in interactive contexts.

  • Augmented action and perception: This refers to tools that increase the normal action and perception capabilities of humans. The system adds virtual information to a user’s sensory perception by merging real images, sounds, and haptic sensation with virtual ones. This has the effect of augmenting the user’s sense of presence, and of making possible a symbiosis between her view of the world and the computer interface. Possible applications are in the medical domain, manufacturing and repair, entertainment, annotation and visualization, and robot tele-operation.
