Re: frequency to mel formula

Hi Jim,

Do you have a feel for why the mel scale is used instead of, say, Bark or ERB scales?

Just curious,

Dear List,

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.

Thanks much,
