Thanks; I do want to go with whatever is standard or most

I want to write a simple application that can

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.
Again, thank you for the advice!
