G10H2250/571 - 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; Details of musical waveform synthesis, i.e. audio waveshape processing from individual wavetable samples, independently of their origin or of the sound they represent Waveform compression, adapted for music synthesisers, sound banks or wavetables

Sub-classes:

G10H2250/575 » Adaptive MDCT-based compression, e.g. using a hybrid subband-MDCT, as in ATRAC 6
G10H2250/581 » Codebook-based waveform compression 2
G10H2250/591 » DPCM [delta pulse code modulation] 0
G10H2250/601 » Compressed representations of spectral envelopes, e.g. LPC [linear predictive coding], LAR [log area ratios], LSP [line spectral pairs], reflection coefficients 9
G10H2250/605 » Dynamic range companding algorithms, e.g. "mu"-law, primarily used in the digital telephone systems of North America and Japan, or A-law as used in European digital telephone systems 1
