Audio Noise Suppressor

Suppression of Acoustic Noise in Speech

Removing back ground noise added to speech is a fundamental problem in mobile devices such as cell phones. There are several well studied methods to suppress noise.

In this Simulink model, I model and simulate noise suppression using spectral subtraction. To better understand this method, please refer to "Suppression of Acoustic Noise in Speech Using Spectral Subtraction," Steven F. Boll, IEEE Transaction on Acrostics, Speech, and Signal Processing, April 1979.
