Sound synthesis with fixed partition size convolution of audio signals

A system comprising:

• a processor;
• a memory coupled to the processor;
• program instructions embodied in the memory an executable by the processor, wherein execution of the program instructions by the processor causes the processor to implement a method, the method comprising:
• converting a frequency spectrum of a segment of an input signal and a frequency spectrum of a corresponding segment of an impulse response function from a floating point data format to a fixed point integer data format;
• multiplying the converted frequency spectrum of the segment of the input signal with the converted frequency spectrum of the corresponding segment of the impulse response function;
• and
• generating a desired convolved signal corresponding to a convolution involving the segment of the input signal and the corresponding segment of the impulse response function in the time domain using multiplication results from said multiplying the converted frequency spectrum.

A non-transitory computer readable medium having program instructions, wherein execution of the program instructions by one or more processors causes the one or more processors to perform a method, the method comprising:

• converting a frequency spectrum of a segment of an input signal and a frequency spectrum of corresponding segment of an impulse response function from a floating point data format to a fixed point integer data format;
• multiplying the converted frequency spectrum of the segment of the input signal with the converted frequency spectrum of a corresponding segment of the impulse response function;
• scaling multiplication results from said multiplying the converted frequency spectrum;
• accumulating scaled results from said scaling multiplication results;
• and
• performing an inverse transform on accumulated signals from said accumulating scaled results to generate a desired convolved signal corresponding to a convolution involving the segment of the input signal and the corresponding segment of the impulse response function in the time domain.
