COMMENTS BY PROFESSOR

Make sure audio and video work together side by side

Remember, if you just have one picture, you neglect so much other information. You don't have to make it too hard, you have to set some limits. You can ask specific questions that work for your program and no one will blame you.

If it's hard, don't go for it.

In the beginning, we can limit to a small data set.

There are open source software of analyzing sound, we can use existing stuff.

Stick to stuff that is already existing and has a lot of support.
