It has been said that one's voice has characteristics that can be measured and quantified in order to recognize and identify a particular speaker. It has also been said that since each brass player has unique lung, oral cavity, tongue, and embouchure characteristics, one's sound will be distinct and different from anyone else's. Can the same or similar technology and analysis that can identify a speaker also identify a particular player? If one's voice can be identified even when disguised, can a player be identified regardless of which instrument one uses or which timbre a player uses to color the sound, i.e. bright, dark? Or would determining a player be more akin to identifying a speaker who has used an electronic voice scrambler?
