normalization method #172

I found in compute-meanvar-stats.py it uses standard scaler to do normalization. For spectrogram, I am not sure if it is right to do normalization on 2D matrix. I have observed that if we apply normalization on 2D matrix, it is a little weird. However, if applied to 1D vector (ravel 2D matrix to 1D) it makes more sense. Do you consider this situation?

Normalization for each feature dimension is pretty common in my opinion. I don't think it's weird.
