|Frequently Asked Questions|
If have found a bug/problem in WaveSurfer, how do I report it?
The WaveSurfer user forum is the official place to report bugs. Write a descriptive step-by-step instruction on how to reproduce the problem. Also, give information on the version of WaveSurfer and the OS/hardware that was used.
I am having problems using a binary version of WaveSurfer, what can I do about it?
Download and install the source version. Do not forget to install Tcl/Tk and Snack first. Run wavesurfer.tcl. There is no compilation/linking. Installation of Tcl/Tk and Snack is usually pain-free process and it will also make it easier to pinpoint any persisting problems.
What relation does WaveSurfer have to Snack?
WaveSurfer is built using the Snack toolkit and the Tcl/Tk language. Snack provides all low level functionality while WaveSurfer is the application which also contains a library of high-level visualization components. Snack is only of interest for advanced users and developers. Users of the binary Windows/Linux releases need never know or worry about Snack or Tcl/Tk.
What audio/DSP hardware will wavesurfer work with?
Basicly audio hardware supported by the standard system drivers. All signal processing is done in software.
When I try to run the Linux binary, I get the error "couldn't load libsnack...: undefined symbol: __bzero" . What's wrong?
The WaveSurfer Linux binary requires that the system has glibc 2.1 or later (e.g. RedHat6.0 or later) Type "ls -l /lib/libc-*" to see what version of glibc is on your system.
How do I get printing to work on Windows?
WaveSurfer creates postscript files for print output. You will need external tools to print and view these. If you have a postscript-capable printer you should install PrintFile. If your printer lacks postscript support, you should also install Ghostscript. In order to view postscript files on the screen you can use GSview. They can be downloaded from http://www.cs.wisc.edu/~ghost/.
WaveSurfer is set-up to use them in their default installation locations (can
be changed in File | Preferences). If you experience problems printing from within WaveSurfer, simply save the postscript image to file in WaveSurfer and print it from Windows.
How can I get the pitch values plotted in the pitch contour pane as a list of numbers?
Simply choose Save Data File... from the pop-up menu and create a text file containing the pitch values.
How do I permanently set the spectrogram parameters for narrow-band analysis?
Adjust spectrogram parameters as desired and choose Save Configuration... to create a configuration for future use.
How can I display one specific channel of a multi-channel sound?
You can use Properties | Waveform | Show channel to control this, same for spectrograms etc. The configuration n-waveforms displays each channel separately in its own waveform pane.
I have downloaded a plug-in for WaveSurfer how do I install it?
Normally plug-ins are installed by choosing one from the list of available plug-ins, File | Plug-ins..., and clicking the Install button. It can also be done manually. Windows users should copy plug-in files to C:\.wavesurfer\1.4\plugins\. Copy both *.dll and *.plug files. C: might be D: or some other drive depending on the system configuration.
Unix users should copy plug-in files to ~/.wavesurfer/1.4/plugins/. Copy both *.so and *.plug files.
Please refer to the README file of the source distribution for information on system wide installation for multiple users.
