Areas of Study
The study of CA could be roughly divided into the following sub-problems:
- 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.
- Feature extraction: sound descriptors, segmentation, onset, pitch and envelope detection, chroma, and auditory representations.
- Musical knowledge structures: analysis of tonality, rhythm, and harmonies.
- Sound similarity: methods for comparison between sounds, sound identification, novelty detection, segmentation, and clustering.
- Sequence modeling: matching and alignment between signals and note sequences.
- Source separation: methods of grouping of simultaneous sounds, such as multiple pitch detection and time-frequency clustering methods.
- Auditory cognition: modeling of emotions, anticipation and familiarity, auditory surprise, and analysis of musical structure.
- Multi-modal analysis: finding correspondences between textual, visual, and audio signals.

Famous quotes containing the words areas of, areas and/or study:
“Adults understandably assume that the level of verbal proficiency a five-year-old displays represents his level of proficiency in all areas of functioning—if he talks like an adult, he must think and feel like one. However, five-year-olds,... belie the promise of adult-like behavior with their child-like, impulsive actions.”
—Dorothy H. Cohen (20th century)
“Helping children at a level of genuine intellectual inquiry takes imagination on the part of the adult. Even more, it takes the courage to become a resource in unfamiliar areas of knowledge and in ones for which one has no taste. But parents, no less than teachers, must respect a child’s mind and not exploit it for their own vanity or ambition, or to soothe their own anxiety.”
—Dorothy H. Cohen (20th century)
“All abstract sciences are nothing but the study of relations between signs.”
—Denis Diderot (1713–1784)
