  • Audio signal quality enhancement based on quantitative SNR analysis and adaptive Wiener filtering
    Patent number: 10224053
    Abstract: An audio signal enhancement method includes: acquiring an audio signal; estimating a signal-to-noise ratio (SNR) of an audio frame of the audio signal; determining a SNR threshold for the audio frame; selecting an audio signal processing technique according to a comparison of the SNR threshold to the estimated SNR of the audio frame; filtering the audio frame using a Wiener filter applying the selected signal processing technique; and outputting the audio frame filtered using the Wiener filter applying the selected signal processing technique. A first-in, first-out (FIFO) signal processing technique is selected when the estimated SNR of the audio frame is less than the SNR threshold, and a log-energy voice activity detection (VAD) signal processing technique is selected when the estimated SNR of the audio frame is greater than the SNR threshold.
