G10H2250/215 - CPC Classification

Classification description:

Aspects of algorithms or signal processing methods without intrinsic musical character, yet specifically adapted for or used in electrophonic musical processing; Mathematical functions for musical analysis, processing, synthesis or composition Transforms, i.e. mathematical transforms into domains appropriate for musical signal processing, coding or compression

Sub-classes:

G10H2250/221 » Cosine transform; DCT [discrete cosine transform], e.g for use in lossy audio compression such as MP3 15
G10H2250/231 » Fermat transform 0
