Sound Signal Processing Using Complex Dynamic Representation
نویسنده
چکیده
Abstract : In this paper we show that a complex dynamic representation (logenvelope and instantaneous frequency) can be used efficiently to compress the spectrum and band−shift a discrete−time signal. The original method and algorithm conceived here do not violate the amplitude−phase relationships typical of natural sound signals. This is achieved by simultaneous modification via transmapping of the instantaneous amplitude and frequency of a signal.

Nonlinear signal processing is an integral part of sensory transduction in the nervous system. Sensory inputs are analog, continuous-time signals with a large dynamic range, whereas central neurons encode information with limited dynamic range and temporal specificity, using fixed-width, fixed-height pulses. Sensory transduction uses nonlinear signal processing to reduce real-world input to a n...

Abstract: Gender recognition and age detection are important problems in telephone speech processing to investigate the identity of an individual using voice characteristics. In this paper a new gender and age recognition system is introduced based on generative incoherent models learned using sparse non-negative matrix factorization and atom correction post-processing method. Similar to genera...
متن کاملLung Sound Noise Reduction Using Gabor Time-Frequency Masking
The Gabor expansion is a mathematical tool, which provides a joint time-frequency representation of a given signal by decomposing it into time-frequency elementary signals called Gabor atoms. It has been used in a variety of signal processing applications, including biomedical signal processing. In this paper we present a time-frequency masking technique based on Gabor expansion for both heart ...

متن کاملPitch and timbre manipulations using cortical representation of sound
The sound received at the ears is processed by humans using signalprocessing that separates the signal along intensity, pitch and timbre dimensions. Conventional Fourier-based signal processing, while endowed with fast algorithms, is unable to easily represent signal along these attributes. In this paper we use a recently proposed cortical representation to represent and manipulate sound. We br...
