G10H2250/541 - CPC Classification

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

• G10H2250/545 » Aliasing, i.e. preventing, eliminating or deliberately using aliasing noise, distortions or artifacts in sampled or synthesised waveforms, e.g. by band limiting, oversampling or undersampling, respectively. 2
• G10H2250/551 » Waveform approximation, e.g. piecewise approximation of sinusoidal or complex waveforms 5
• G10H2250/571 » Waveform compression, adapted for music synthesisers, sound banks or wavetables 22
• G10H2250/611 » Waveform decimation, i.e. integer division of the sampling rate for reducing the number of samples in a discrete-time signal, e.g. by low-pass anti-alias filtering followed by the actual downsampling 0
• G10H2250/615 » Waveform editing, i.e. setting or modifying parameters for waveform synthesis. 24
• G10H2250/621 » Waveform interpolation 20
• G10H2250/631 » Waveform resampling, i.e. sample rate conversion or sample depth conversion 24
• G10H2250/635 » Waveform resolution or sound quality selection, e.g. selection of high or low sampling rates, lossless, lossy or lossier compression algorithms 3
• G10H2250/641 » Waveform sampler, i.e. music samplers; Sampled music loop processing, wherein a loop is a sample of a performance that has been edited to repeat seamlessly without clicks or artifacts 124
• G10H2250/645 » Waveform scaling, i.e. amplitude value normalisation 9
