The frequency, measured in Hertz of a sound, is also known as the pitch by musicians. A higher frequency corresponds with a higher, sharper pitch and a lower frequency corresponds with a flat or lower pitch.Some musically trained people are able to detect frequencies as little as 2 Hz. In...

Thus, pitch (like volume) is perceived exponentially by our ears: at every octave, the frequency doubles. Figure 4-1. Graph of perfect A4 and A5 tones side by side Octaves are split up into 12 semitones. Each adjacent semitone pair has an identical frequency ratio (at least in equal-...

For example, in species where males are larger than females, low‐frequency male vocalisations are expected to be selected by intra‐sexual selection, inter‐sexual selection and selection to identify sex, but these selective forces may act antagonistically on female vocalisations. Consistent with ...
Inamura and Sata [32], Sexton and Stone [33], and Tsao et al. [34] all conducted the experiments and showed that the chatter could be greatly suppressed when suitable amplitude and frequency are chosen. Insperger and Stepan [35] used the SDM to construct stability diagrams for variable ...

temporal morphing is a minor effect if the sampling frequency is high but it can be significant when, for example, using a stylized pitch contour with few pitch samples. modifications can be done between entire wav files or between corresponding intervals as specified in a textgrid or other anno...
