Description

Contains m-files to train and implement the MMSE noise tracking algorithm described in:

Why submit files to the FEX that refer to data files on your hard drive? Perhaps your going to update this submission with your computer login details? ;-)

I guess you mean the train data? I used a lot of train data, which I cannot upload. You can either use your own train data, or use the pretrained gainfunctions I have included, in which case no training is required. See the example at the end of Description.doc. The m-files I used for training were added to assist people who want to do their own training.

Updates
16 Jul 2010

The variable names in GainTables.mat have been changed to match those used in NoiseTracker.m, that is
G1 => G_A
G2 => G_A2
Gd2new => G_D2
02 Sep 2010

Added an example to Description.doc and explained how the noise tracker may be used at different sampling frequencies.
24 Dec 2010

- Removed potsband.m (available online elsewhere, see Description.doc)
- Added pdf of the paper + IEEE copyright statement

The safety net in NoiseTracker.m assumed a sampling frequency of 8 kHz. NoiseTracker.m now reads the noisy speech from a .wav-file and the sampling frequency is automatically detected.
