Differentiable wavetable synthesizer using plurality of machine learning models to reduce computational complexity of audio synthesis

The present disclosure describes techniques for differentiable wavetable synthesizer. The techniques comprise extracting features from a dataset of sounds, wherein the features comprise at least timbre embedding; input the features to the first machine learning model, wherein the first machine learning model is configured to extract a set of NL learnable parameters, N represents a number of wavetables, and L represents a wavetable length; outputting a plurality of wavetables, wherein each of plurality of wavetables comprises a waveform associated with a unique timbre, the plurality of wavetables form a dictionary, and the plurality of wavetables are portable to perform audio-related tasks. Finally, the said wavetables are used to initialize another machine learning model so as to help reduce computational complexity of an audio synthesis obtained as output of the another machine learning model.

Method for the synthetic generation of a digital audio signal

A method for the synthetic generation of a digital audio signal by means of periodic sampling of a waveform shall permit the user a particularly simple and intuitive access to the changing and creative transformation of the waveform on which the sampling is based. For this purpose, according to the invention, the waveform is specified by using control points, which, in addition to position parameters, may contain further attributes, of which the parameters and attributes can be changed individually over time by means of control signals or spontaneouseous intervention. The control-point values which result in this way can be interpreted either as direct amplitude-period phase or as magnitude-frequency or phase-frequency pairs. A continuous waveform is generated by interpolation or approximation of the control points and the parameters/attributes of the latter, which assume a time-specific value depending on the current control signals and other influences, and is used for further processing, e.g. spectral band limiting.
