Fix problems in Matlab Program in Signal Processing

Objective: Speech enhancement using binary mask generated using noise estimation technique Here are some of the items you need to fix. First, you need the maintain the loop with looping variable corresponding to the time frame. Specifically, variable 'k' from gt(m,k:k+len-1) needs to be updated as you advance the time frame. When you have the output of mth frequency channel, i.e., gt(m,k:k+len-1), it doesn't make sense to take its fft. Rather, find out the average or rms value of that frame and it will be the spectrogram value in nth time frame and mth channel. If you put together values from all frequency channels in a vector, then it will be the spectrum of the nth time frame, but with the logarithmic frequency resolution.
