摘要: An electronic device for suppressing noise in an audio signal is described. The includes a processor and instructions stored memory. receives input computes overall estimate based on stationary estimate, non-stationary excess estimate. also adaptive factor Signal-to-Noise Ratio (SNR) one or more SNR limits. A set of gains computed using spectral expansion gain function. function the factor. applies to produce noise-suppressed provides signal.
