I wonder if quanta are made from beat frequencies: hf = h|f1- f2|
where |f1- f2| is the absolute value of the difference between the frequencies of two interfering *classical* vibrations. Perhaps ordinarily the existence of the other frequencies produce no observable effects but under special circumstances they do. What I am proposing is related to the phenomena of quantum beats but quantum beats involve the interference of two quanta or photons rather than trying to explain why quanta exist. This article gives a history of the subject and interestingly the existence of quantum beats has often been denied because semi-classical quantum theory says they are impossible but quantum electrodynamics does predict them. https://bayes.wustl.edu/etj/articles/quantum.beats.pdf BTW the beat concept also played a role in thought of Louis de Broglie.
