Abstract: A system and method for audio synthesizer utilizing frequency aperture cells (FAC) and frequency aperture arrays (FAA). In accordance with an embodiment, an audio processing system can be provided for the transformation of audio-band frequencies for musical and other purposes. In accordance with an embodiment, a single stream of mono, stereo, or multi-channel monophonic audio can be transformed into polyphonic music, based on a desired target musical note or set of multiple notes. At its core, the system utilizes an input waveform(s) (which can be either file-based or streamed) which is then fed into an array of filters, which are themselves optionally modulated, to generate a new synthesized audio output.

Abstract: A method, apparatus, and system (48) are disclosed for use in synthesizing an audio performance (50) in which one or more acoustic characteristics, such as acoustic space, microphone modeling and placement, can selectively be varied. In order to reduce processing time, the system utilizes pseudo-convolution processing techniques (54) at a greatly reduced processor load. The system is able to emulate the audio output in different acoustic spaces, separate musical sources (instruments and other sound sources) from musical context; interactively recombine (56) musical source and musical context with relatively accurate acoustical integrity, including surround sound contexts, emulate microphone models and microphone placement, create acoustic effects, such as reverberation (58), emulate instrument body resonance and interactively switch emulated instrument bodies on a given musical instrument.
