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 system and method for creating and/or rearranging musical content on a mobile device such as a cellphone or personal digital assistant (PDA), or on a computer for subsequent download and interactive playback on a mobile device. The method includes the creation and use of a digital music file, preferably consisting of MIDI sequence data, defining a musical composition having distinct musical parts, and the creation and use of a control file used in the rearrangement of the musical parts. The control file includes a plurality of control parameters for the musical composition, including which musical parts are active for each measure of the musical compositions. A user interface is included for allowing a user to alter one or more of the control parameters.
