Used ffmpeg to convert the audio portion of my mp4 file to match the simpons file as closely as possible, but waveforms still do not show up using my file.

BTW, attempting to use the simpsons and tears files, I do get what I'm assuming are audio waveforms at the bottom of the green area which I do not get with my mp4 files. The waveforms from these files appear to be very "vague", though, and would not be useful for aligning tracks via the audio waveforms.
