Real-Time Broadband Noise Reduction

Robert Hoeldrich and Markus Lorber
A real-time implementation of a broadband noise reduction method based on non-linear spectral subtraction is proposed. To prevent processing distortions in form of musical noise, over-subtraction is applied to the degraded signal spectrum. Furthermore, time-averaging is used to reduce the variance of the estimated signal-to-noise ratio (SNR). A masking threshold obtained by spectral smoothing leads to further reduction of audible processing distortions.

Plone makes heavy use of CSS, which means it is accessible to any internet browser, but the design needs a standards-compliant browser to look like we intended it. Just so you know ;)
