Mutating spectral resynthesizer system and methods

A device for audio sound generation, comprising:

• a processor;
• an input buffer coupled to the processor;
• an analog to digital converter coupled to the input buffer and configured to write digitized audio data into the input buffer;
• and
• a memory for storing executable instructions, the processor executing the executable instructions to:
• read a buffered segment of audio data from the input buffer upon receiving an analysis trigger;
• and
• analyze an audio input upon receiving the analysis trigger, wherein the analysis comprises:
• performing a transform on the buffered segment, thereby generating a spectrum and performing a transform on a portion of the buffered segment generating a fast spectrum;
• blending lower frequencies of the spectrum with higher frequencies of the fast spectrum, thereby generating a blended spectrum;
• spectrally integrating the spectrum or the blended spectrum thereby generating an integrated spectrum;
• finding a number of peak frequencies in the spectrum and a number of associated gains;
• and
• resolving the number of peak frequencies thereby generating a peaks array comprising a number of associated frequency parameters and associated gain parameters;
• synthesizing audio upon receiving an analysis clock comprising steps of:
• configuring a number of digital oscillators with associated frequency parameters and associated gain parameters from the peaks array;
• and
• combining each of a number of oscillator outputs thereby generating synthesized audio;
• and
• converting the synthesized audio to an analog audio output.
