Quick Setup

Software Required

The Triton software package was developed using MATLAB, a hi-level programming language.  MATLAB (www.mathworks.com) must be installed on the current computer for Triton to function.  MATLAB is available for many operating systems including Windows, Mac and Linux.  However, Triton was developed using Windows XP sp2 and MATLAB 7.0 (Release 14) and has not been extensively tested with other operating systems or versions/releases of MATLAB.

Install Triton

• To get the most recent release of Triton: Download the zip compressed file (eg. Triton1.64.20070709.zip) at ftp://cetus.ucsd.edu/outbox/Triton/

• Uncompress the zipped file in an empty folder or directory, such as D:\Triton

• Set MATLAB’s path to include the directory where Triton was uncompressed by using the MATLAB File pull-down and ‘Set Path…’

• Click the ‘Add Folder…’ button, browse and select the folder containing the version of Triton that you want to run, Remove other versions of Triton from the path with the ‘Remove’ button.  Click ‘Save’ and then ‘Close’.

Start Triton

• Start Matlab and at the command prompt (>>) type “triton” to run the application. 

Three windows will be displayed: Plot, Control, and Message. 

• Plot Window (Right) - Displays Long Term Spectral Average (LTSA), spectrogram, spectra and time series plots.
• Message Window (Lower Left) - Keeps a record of the users actions and displays Plot Window cursor location along with ‘pick’ data.
• Control Window (Upper Left) – Control settings for Plot Window.

Load and View an Example Sound File

• Use the Control Window File pull-down menu to open a WAV file.

• In the Triton software directory, select humpback.wav and click Open.

• Click OK or set the start time of the WAV file.  The WAV file will then be opened up as a time series in the Plot Window.

• The plot settings can be changed within the blue section in the Control Window.  Set the Plot Length to 20 seconds to view the whole file.

Select the Spectrogram button at the top of the Control Window to display the WAV file data also as a time-frequency plot.

• Adjust some of the spectrogram plot parameters and listen to the WAV file sound. 

- Set Plot Frequency End to 2000

- Set FFT Length to 3000

- Set Brightness to -5

If your computer has sound playing capabilities, play the sound by pressing the   button at the bottom right of the Control Window. 

Based on above changes, the Plot Window should look like the following:
