Navigation

Why does a command line screen come up when I open SoundRuler?
That screen displays code warnings and errors. When things do not work as they should, please paste the contents of the black screen into your bug report.

I would prefer to navigate by scrolling instead of slicing up the sound file.
That is perfectly feasable. Sectioning was used at the beginning as a simple solution for RAM limitations and navigation speed during the analyses. Since it is not great but it works, this matter did not make it to the top of the priority list yet.

Analysis

How do I erase the green bars when I make a wrong click?
Right-click (Ctrl+click in Macs) on the plot and choose ′Erase selections′.

Is it possible to make the program plot the oscillogram of the call with a constant duration (for graphs and CCA)?
SoundRuler provides control over the amount of sound that is added around the call that is recognized in the section. The area ′Plot: time displayed around the call′ in the menu Options, Section defines how much sound is incorporated in the next graph.

Why does the program exceed the green bars that I define when I perform manual recognition in the section?
To make the program follow your manual ′green bar′ selections exactly, select ′centered′, ′percentage′ and 100%.
To make it select a constant total duration, select ′centered′, ′milliseconds′ and specify a duration. The program will select the desired duration, centering it among the green bars in manual selection or the blue gate in automatic recognition.

Why doesn′t SoundRuler measure variable xyz?
Please let us know if variable xyz is important for your work. The measurement might be easy to implement and it might just not have occurred to us to incorporate it.

Graphing

Why doesn′t SoundRuler save my spectrograms as Windows metafiles?
Metafiles are vectorial, meaning that the image is defined as a series of geometric objects on a coordinates map. Spectrograms are generated as bitmaps, where the pixel darkness is specified point by point. The metafiles format in matlab′s libraries will not include bitmap images.
The other types of plots that SoundRuler generates are vectorial. The vectorial plots are converted easily to bitmap, so you can save them both as metafiles or as bitmaps (bmp, tiff, png and jpg).
Some traditionally vectorial formats like eps and ai now accept having a bitmap inserted as an extra object among the others. Try using one of these formats when you want to save spectrograms and other plots together.

Code

Where are the source files?
What language is used to write SoundRuler?

SoundRuler is developed in M-file scripts. These are implemented by Octave, Scilab (open, free) and Matlab (proprietary). The source files are in the script releases.

A feature in the help file seems to be missing from my version of SoundRuler.
We are dealing with five types of releases that run on different libraries. It is not currently possible to have all features present and identical in all releases.

Will SoundRuler′s script version run in free programs such as Octave or Scilab?
The math code should mostly work, but until the last time we tested it, the graphical interface support in such environments did not yet attend SoundRuler well. We keep an eye on new developments and hope to be able to make SoundRuler available on free math environments soon.

Can SoundRuler coexist with Matlab installations?
Yes, there should be no problems.

Troubleshooting

My settings files stopped working.
Settings files are sensitive to sampling rate. To use them with a new sampling rate, you might have to adjust the settings that are based on sample number.
