Depending on your needs, maybe R is a easier language. I'm using it for one year now, it does statistical analysis, graphs, maps and sound analysis too. With png, tuneR and seewave libraries you need one line to read a .wav, other to get the matrix of data, and other to put it into a png image or see it on screen. The points of being designed to analyze data and being easier to use are two advantages for me. For instance, R numbers tables and arrays starting from 1, not 0 like most programming languages. It makes our human brain much more comfortable with the already complicated scripts. I think you should take a look at it: http://www.r-project.org/
Good luck!
