MEL conversions

This HTML document (modified by JT from a semitone conversion form written and provided by J.R. de Pijper, IPO, Eindhoven) allows you to convert frequency values expressed in Hertz to a mel scale which expresses frequency in terms of psychophysical metrics (i.e., perceived pitch). The formula mel= 1127.01048 * log(f/700 +1) is used here (Stevens & Volkman, 1940). Conversion "MEL to Hz" is also possible.

For a more complete and user-friendlier conversion page, please consult Hartmut Traunmüller's page at http://www.ling.su.se/staff/hartmut/umrechnung.htm
