Re: frequency to mel formula
I don't know if this is the first reference to the mel scale, but it's one that I have read before and seen cited:
Stevens, S.S. & Volkmann, J. (1940) The relation of pitch to frequency: A revised scale. The American Journal of Psychology 53(3), 329-
I hope this helps.

Subject: frequency to mel formula
On the Wikipedia page
a formula for computing frequency in terms of mels is given as:
mel = log(1 + fr/700)*1127 .
It is easily inverted to fr = 700*exp(mel/1127 - 1) .
My question is: Where do these formulas come from? I.e., I need
a journal reference for these formulas.
