A method of and system for generating audio having pitch attributes of an incoming audio stream. The method comprises of receiving a digital audio input. The audio data is analyzed upon receiving an analysis trigger indication which can be synced with the audio tempo. The analysis includes a Fast Fourier Transform of a segment of digital audio data.

The integrated spectrum is process to find a number of peak frequencies in the spectrum and their gain. A number of the peak frequencies are used to program a number of oscillators and the parameters determined during analysis and controllable attributes and characteristics of the oscillators. The synthesis is performed upon receiving an analysis clock. First, a number of digital oscillators are configured with the associated frequency parameters and gain parameters from the peaks array; The number of oscillators configured according to the audio pitch analysis and are generated an oscillator output at the frequency and gain specified in the peak array. These oscillator output are summed together thereby generating synthesized audio.
