Computer Audition - Areas of Study

Areas of Study

The study of CA could be roughly divided into the following sub-problems:

  1. Representation: signal and symbolic. This aspect deals with time-frequency representations, both in terms of notes and spectral models, including pattern playback and audio texture.
  2. Feature extraction: sound descriptors, segmentation, onset, pitch and envelope detection, chroma, and auditory representations.
  3. Musical knowledge structures: analysis of tonality, rhythm, and harmonies.
  4. Sound similarity: methods for comparison between sounds, sound identification, novelty detection, segmentation, and clustering.
  5. Sequence modeling: matching and alignment between signals and note sequences.
  6. Source separation: methods of grouping of simultaneous sounds, such as multiple pitch detection and time-frequency clustering methods.
  7. Auditory cognition: modeling of emotions, anticipation and familiarity, auditory surprise, and analysis of musical structure.
  8. Multi-modal analysis: finding correspondences between textual, visual, and audio signals.

Famous quotes containing the words areas of, areas and/or study:

    “... two great areas of deafness existed in the South: White Southerners had no ears to hear that which threatened their Dream. And colored Southerners had none to hear that which could reduce their anger.”
    —Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 1, ch. 16 (1962)

    “The discovery of the North Pole is one of those realities which could not be avoided. It is the wages which human perseverance pays itself when it thinks that something is taking too long. The world needed a discoverer of the North Pole, and in all areas of social activity, merit was less important here than opportunity.”
    —Karl Kraus (1874–1936)

    “Very useless things we neglect, till they become old and useless enough to be put in Museums: and so very important things we study till, when they become important enough, we ignore them—and rightly.”
    —Samuel Butler (1835–1902)
