Sound Analysis Software

For some time, we have been considering how to test the stand quantitatively. We decided that we will record the speaker and then compare the recording to the original audio file and find a way to calculate the difference between the two files. This left the question of what software we could use to do this analysis with. After some research, I identified several programs that may be able to compare two audio files and give a numerical representation of the difference between the two. Among them are Sonic Visualiser, Praat, Audio DiffMaker, and musicg. All of these programs have been downloaded and will be experimented with to see if they can produce the desired results, and of them, which can produce the best results.
