>>68899763I did my own analysis. If you're going only by the bright parts all you're doing is analyzing the frequencies of voices talking. Congratulations, you proved that females and males have different harmonics and thus different timbres to their voice. What a mystery.
What you wanna be doing is analyzing the ambient noise of the rooms they're in which is found in the silence BETWEEN speech. In picrel left half is elira's room silence and just to the left of my cursor is vox's room silence. Taking into account the fact that they're likely using different mics, and different audio setups, there's no appreciable difference in the silences. (Yes, 0-400hz is a good place to search for low frequency room vibrations)
