Comparative presentation of two FHE values for the dramatic tenor (T1) Plácido Domingo (2632 Hz) and the lyric baritone (B2) Mario Cassi (3013 Hz) at comparable pitch f4 (362 vs. 361 Hz). The yellow highlighted area marks the frequency band defined for the calculation of all timbre parameters. The vibrato is calculated at the harmonic marked in red (VR, VE). The lower half of both examples shows the progression of sound energy within the investigated frequency band. The black bar indicates the frequency at which 50% of the energy is reached (FHE).
