Mean Frequency Amplitude (MFA)
This corollary (minor) feature calculate the amplitude at a dynamic range of 500Hz around the mean frequency. MFA is sometimes useful for sub-syllabic segmentation because it changes its value sharply during some sub-syllabic transitions. Also, the gap between amplitude and MFA (use ‘group features’ to observe them together) sometimes changes in an interested manner during the song and during song development.
