Audio Noise Suppressor

Suppression of Acoustic Noise in Speech

3 Ratings



No License

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.

Hey good work.
I refferd the IEEE paper but had some doubts, ur demonstration solved it all. thanks a lot.

Very good example. Also, demonstrates embedded matlab functions too.

Hi Ali.
This simulink block set dont run in mi pc. there are several block functions named fcn, that dont make nothing because Matlab dont aknowledge thaese function blocks, and dont lets open these blocks to see inside them. thanks for write me back telling me if you have the answer to this issue ASAP.
