Electrodograms for the MCI rise-fall pattern in octave 3 (a) and octave 4 (b) with 2 semitone intervals, using Smt-LF mapping. Smt-LF, which has an upper cut-off frequency of 1502 Hz, has filtered out most of the octave 4 signal's higher partials. The two electrodograms also demonstrate how Smt-LF results in a transposition to higher frequencies (see [2]).
