Abstract
A method of performing audio synthesis is disclosed. An audio event is input to an audio algorithm along with associated parameters including source sample data. An interpolation function is provided and the source sample data are interpolated to generate one or more interpolated samples based on the source sample data. A filter function is provided and at least one of the interpolated samples is filtered to generate a filtered sample. A gain function is provided and the filtered sample is processed to generate a gained sample. At least one of the interpolation, filter, and gain functions include outputting an earlier-calculated value along with an estimated difference value in lieu of calculating a new value.
