Hi Francois,
I want to how to calculate the power ratio of one band to all bands, I followed the step suggested by SBeumer, That is, compute spectrum normalization, and get the results. Then I export it to matlab, get the TF matrix, I want to know how to calculate the ratio of one band to the whole band from the result of spectrum normalization.
Maybe I should calculate it based on the results of the time-frequency？Just sum up to the total power and divide the power of one band by that total power?
