Title: METHOD FOR TRANSFORMING A NOISY AUDIO SIGNAL TO AN ENHANCED AUDIO SIGNAL
Abstract:
A method transforms a noisy audio signal to an enhanced audio signal, by first acquiring the noisy audio signal from an environment. The noisy audio signal is processed by an enhancement network having network parameters to jointly produce a magnitude mask and a phase estimate. Then, the magnitude mask and the phase estimate are used to obtain the enhanced audio signal.
