traceur201@piefed.socialto No Stupid Questions@lemmy.world•[SOLVED] If I subtract a semitone (100 cents) from 1 Hz, what is its frequency in Hz after that?English34·14 days agoCents are a measure of difference between two frequencies and can’t be converted directly to hz on its own.
An initial frequency in hz and an offset in cents can be used to calculate a second frequency in hz, such as in your initial question. Using the formula from wikipedia f1 * 2^(c/1200) = f2, we get 1hz * 2^(-100/1200) = .9439hz. Note that +1200 cents is double (2^1) and -1200 cents is half (2^-1) the original frequency
