Design and Realization of the Birdsong Analysis and Identification System

On the basis of LabVIEW platform, a birdsong analysis system –Song Lab which has variety of analysis functions and able to handle the large amount of data files was developed. The related key techniques of system design and development are researched in this paper, including large data processing, color adjustment, the processing of feature information, etc. The function of large data processing is used to solve data reading efficiency problem, color adjustment are applied to adjust the appearance of the spectrogram plot, and feature information is used to realize the characteristics of information extraction, analysis and comment. Finally, the birdsong analysis and identification system is built and some substantiation analysis has been made with the sampled data using this software, the results indicate that this system has accurate analysis results; it can provide a good technical support for researches in the field of animal acoustics.
