The paper gives an overview of the capacities of the software solutions for a sound analysis system based on the program development environment LabVIEW and shows some applications of the system by using suckling grunts of domestic pigs Sus scrofa as an example.
LabVIEW represents a versatile tool for the development of sound analysis software including sound processing and sound statistics. Particularly, the increasing need for flexible numerical processing of different acoustic parameters can be considered. The graphical object -oriented language allows programming without special experience because it uses terminology, icons and theories familiar to scientists and engineers. LabVIEW is available for Macintosh, Sun, HP-UX, Windows 95, Windows NT, Windows 3.1., and can also be used as a teaching tool to gain technical knowledge of signal analysis and signal processing.
Paralleled by behavioural observations, the bioacoustical studies of animals at various levels, including the incorporation of techniques that are used in animal communication, human speech recognition or in technical acoustics, are able to reveal the specific meaning of vocalisations. Based on the example of the analysis of suckling grunts of domestic pigs the impact of an application of the system developed in our group is demonstrated.
