MFCCs are useful for speech & music analysis. For music, why isn't the 12-tone scale used instead of the mel scale?
As far as I understand, the mel scale was developed empirically using something akin to "just noticeable differences" in a subject's perception of frequencies. The scale ends up being a log ...

How do you calculate RMSE in degrees for a DOA estimator system with multiple incoming signals?
Let's say you have a system with 1 transmitter and 5 receivers. We'll use the MUSIC algorithm to determine DOA of incoming signals.
If we have 1 signal (at 0° for example), it's easy to calculate ...
