Boll Spectral Subtraction

The spectral Subtraction Method for enhancement of noisy speech.

Description

The spectral Subtraction Method for enhancement of noisy speech signals proposed by Boll 79. The method implements spectral averaging and residual noise reduction proposed in the paper. Note that the first 0.25 sec of the speech signal is assumed to be noise only and is used to model the noise signal.
