Wavesurfer is a practical signal processing tool to investigate waveforms. It can be obtained from http://sourceforge.net/projects/wavesurfer/

After downloading and extracting, running may lead to shared library problem,

wavesurfer - libxft problem

We may get suprised if we see that we have already got the library,

wavesurfer - check presence of libxft

In fact being an 32 bit problem, wavesurfer needs 32 bit version of libxft2

Solution may be installing 32 bit version of libxft2 as follows,

wavesurfer - installing libxft

wavesurfer - recheck presence of libxft

We now are able to get the simple interface of wavesurfer

wavesurfer - running wavesurfer
