Abstract
As consumer electronic technology continues to advance with lower power, higher speed, larger data capacity, and lower costs, the ability to collect large acoustic data sets becomes more practical. However, working with these large data sets can be challenging and requires different approaches to managing and analyzing the data than traditionally have been used with small data sets. TRITON is a software package developed for working with long-term, wide-band, multi-terabyte, acoustic data sets. One of TRITON’s primary functions is to make long-term spectrograms from a large group of small (1 Gbyte) sequential data files. These long-term spectral averages provide a means of quickly evaluating long durations (hours) of wide-band data for sounds such as animal calling bouts and permit the user to zoom in to traditional spectral/time domain displays for finer scale analysis. TRITON has a graphical user interface and is based in MATLAB, which allows for easy modifications for specific data processing and analysis requirements. Examples of this are whistle and echolocation click detectors developed as TRITON extensions.
