Time-Amplitude Parametrization

  • Jérôme Sueur
Part of the Use R! book series (USE R)


The techniques to take time ×-amplitude measurements first consist in measuring signal and pause durations either through a manual and visual process or with the help of an automatic segmentation process. Because time variations are tidily linked to amplitude variations, amplitude modulations properties can also be estimated through a Fourier analysis. The calling song of a Mediterranean cicada and of a Caribbean frog is used to illustrate how much these manual and automatic techniques can be useful for sound description.
