Abstract

A system and method may be configured to process an audio signal. The system and method may track pitch, chirp rate, and / or harmonic envelope across the audio signal, may reconstruct sound represented in the audio signal, and / or may segment or classify the audio signal. A transform may be performed on the audio signal to place the audio signal in a frequency chirp domain that enhances the sound parameter tracking, reconstruction, and / or classification.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Patent Application Serial No. 13 / 205,535, entitled "System and Method for Processing Sound Signals Including Transforming Sound Signals into the Frequency-FM Domain," filed August 8, 2011, which The entire contents of are incorporated into this application by reference. technical field [0003] The present disclosure relates to processing an audio signal by utilizing a frequency modulation domain that transforms the audio signal into a frequency modulation domain that specifies coefficients related to signal strength as a function of frequency and fractional chirp slope. Background technique [0004] In general, conventional sound processing involves transforming the audio signal for various time windows from the time domain to the frequency domain. Various types of signal processing techniques and algorithms may then be subjected to the signal in the frequency domain before...
