G10H2250/131 - 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

Sub-classes:

G10H2250/135 » Autocorrelation 31
G10H2250/141 » Bessel functions, e.g. for smoothing or modulating, for FM audio synthesis or for expressing the vibration modes of a circular drum membrane 1
G10H2250/145 » Convolution, e.g. of a music input signal with a desired impulse response to compute an output 12
G10H2250/151 » Fuzzy logic 1
G10H2250/155 » Graham function, i.e. mathematical description of the fluid dynamics of air flowing through a gap, where there is a given pressure differential on either side of the gap, e.g. to model air velocity in wind instruments for physical modeling sound synthesis 0
G10H2250/161 » Logarithmic functions, scaling or conversion, e.g. to reflect human auditory perception of loudness or frequency 8
G10H2250/165 » Polynomials, i.e. musical processing based on the use of polynomials, e.g. distortion function for tube amplifier emulation, filter coefficient calculation, polynomial approximations of waveforms, physical modeling equation solutions 3
G10H2250/211 » Random number generators, pseudorandom generators, classes of functions therefor 35
G10H2250/215 » Transforms, i.e. mathematical transforms into domains appropriate for musical signal processing, coding or compression 18
G10H2250/261 » Window, i.e. apodization function or tapering function amounting to the selection and appropriate weighting of a group of samples in a digital signal within some chosen time interval, outside of which it is zero valued 7
