A method of and system for generating audio having pitch attributes of an incoming audio stream. The method comprises receiving a digital audio input. The audio spectrum is analyzed and integrated over segments of digital audio data upon receiving analysis triggers which can be synced with the audio tempo. The integrated spectrum is processed to find peak frequencies in the spectrum and their associated gain stored in a peaks array. The peak frequencies are used to program the oscillators controllable attributes and characteristics. The synthesis is performed upon receiving an analysis clock. A number of digital oscillators are configured with the associated frequency parameters and gain parameters from a peaks array. The oscillators are configured according to the audio pitch analysis and generate an oscillator output at the frequency and gain specified in the peaks array. These oscillator outputs are summed together generating synthesized audio.

Mutating spectral resynthesizer system and methods

In one invention embodiment two microphones are attached to the ear cup and are configured as an end-firing array. The end-firing array suppresses unwanted sounds using an adaptive spectral method and spectral subtraction. According to a second embodiment, Automatic Calibration of an end-firing Microphone Array is provided.
