Huh, it’s possible! And also possible that a player’s speed might vary slightly, creating a subtle waver that becomes a sonic fingerprint.
Some quick math says a player being off by 0.1 rpm is about the threshold of audible difference (5 cents, though more like 0.5 cents to a highly trained ear).
Anecdotes here of people seeing much larger variances: https://www.whatsbestforum.com/threads/turntable-speed-variances-and-acceptable-levels.15428/ Don’t have total confidence in their methods, but your theory is credible.
