Triton

The Triton Software Package is aimed at evaluating acoustic data that is usually single-channel, long duration, continuous and scheduled duty-cycle time series. The time series data are often transformed to the spectral domain for evaluation as power spectra, spectrograms and Long Term Spectral Averages (LTSA). LTSA plots allow large time-series data sets to be viewed and analyzed, including searching for, noting, and evaluating acoustically significant events, such as dolphin and whale calls or anthropogenic sources. Triton provides the necessary tools to quickly review a large data set via an easy to use graphical user interface (GUI).

What is Triton for?

• Read raw HARP data and convert into XWAV files. XWAV files are similar to WAV files, but also may contain additional header information such as instrument location, depth, name, and most importantly, time and date.
• Display, modify, and advance through plot frames of time series, spectrogram, and spectra from single and multi-channel WAV and XWAV files.
• Create and display LTSAs from a collection of WAV or XWAV files providing long term spectrograms with quick and easy linking to the finer-scale originating WAV or XWAV files by simply clicking on an event of interest in the LTSA plot frame.
• Save displayed data as mat file, WAV, XWAV, JPEG, or other graphical file types.
• Decimate high sample rate data files and save as lower sample rate XWAVs to allow for easier analysis of low-frequency sounds, for example, baleen whale call analysis from ultrasonic data.
• Easily add user-developed features with the Remora tool.

Remoras

Remoras are user-developed MATLAB software routines that can be added into Triton. Remoras provide a means to allow users to customize Triton to fit their own specific needs without modifying Triton's core routines.
