The main user interface window allows users to navigate the files and
command the analysis, displaying menus, plots and results.
Plots can be edited and exported for reports or presentations.
Cross correlation analysis can be used to determine the overlap among the graphical
representation of analyzed calls. It can be based on the oscillogram, the amplitude spectrum or the
spectrogram, and the maximal correlation value is frequently used as an index of call similarity.
The CCA is also used to determine the time delay between microphones recording a same sound
from various distances.
Results of Cross Correlation analysis displayed in MS Excel.
The tuning curve is a custom filter allows the user to specify any filter shape and apply it ′on the fly′
to sound files as they are read from the hard disk. One can, for example, specify the transfer
function of a female′s ears, and then visualize, listen to and measure recorded male calls the
same way that the female′s brain would receive them.
This is a didactic module to help with calculations of the math behind sound generation,
propagation and perception.
