Abstract
A method implemented in an audio synthesis device for synthesizing an audio signal is provided. The method includes determining a first plurality of harmonics based on a sinusoidal oscillator, at least two of the first plurality of harmonics being calculated in parallel, scaling the first plurality of harmonics according to a scaling parameter, determining a first sum of the first plurality of scaled harmonics to generate a first sample of the plurality of samples, determining a second plurality of harmonics based on the sinusoidal oscillator, at least two of the second plurality of harmonics being calculated in parallel, scaling the second plurality of harmonics according to the scaling parameter, determining a second sum of the second plurality of scaled harmonics to generate a second sample of the plurality of samples, and causing playback, on the speaker, of at least the first sample and the second sample.
