Exercises

Abstract

SonoScape is a powerful software devoted to the computation of sonic files by the application of the Acoustic Complexity Indices. The illustration of detailed exercises regards primarily:

• 1. How to set the Energy filters reducing the discretion in the selection of thresholds, a necessary step to correctly apply the ACI metrics and to obtain the sonic and acoustic signatures.

• 2. Working with the energy filter in order to exclude every signal that does not belong to environmental sonic sources and that mask biophonic signals.

• 3. Working with the sonic signature, discovering the use of this semiotic object obtained by using ACIt_f.

• 4. Working with near/far sonic field. This exercise introduces to the delimitation of far and near fields, a necessary passage to couple sonic to landscape data.

• 5. Working with the Sonic signature across landscape.

• 6. Working with the temporal scale. The aggregation of the ACI metrics at different temporal scales allows to evaluate the effect of temporal aggregation.

• 7. Working with the fractal dimension of the Ecoacoustic Events at dawn. In this exercise, the fractal dimension of ecoacoustic events has been calculated.

• 8. Graphing Ecoacoustics Events. Plotting the ecoacoustics event codes, composed of three digits into a ternary plot return a representation of the spatial distribution of the ecoacoustics events. This design is useful to make confrontation between different files/location/time, etc.
