Dear members of the list, I am looking for the reference of first use of the equation m = C log(1+f/700) known as mel frequency scale transformation. In Wikipedia says that the scale was originated by Stevens, Volkman and Newman in 1937 (J. Acoust. Soc. Am 8(3) 185--190), but the paper only has tabulated data and no equation. The paper by S.B. Davis & P. Mermelstein (1980), "Comparison of parametric representations for monosyllabic word recognition in continuously spoken sentences", IEEE Trans. on ASSP 28, 357-366 is usually cited in the speech recognition community as origin of MFCCs, but the equation is absent there as well.
