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.
Claims5
A method for transforming a noisy audio signal to an enhanced audio signal, comprising steps:
- acquiring the noisy audio signal from an environment;
- processing the noisy audio signal by an enhancement network having network parameters to jointly produce a magnitude mask and a phase estimate;
- using the magnitude mask and the phase estimate to obtain the enhanced audio signal, wherein the steps are performed in a processor.
