All you need is libsndfile and the standard C or C++ libraries. Note that gnuplot will just plot the sample values, not the analog waveform represented by them. If the signal contains significant energy at high frequencies (say FS / 10) just plotting the samples will provide a poor idea of the waveform. One solution in that case is to upsample first.
