Nope, not really. Been too busy with moving, working, getting married, etc. I did eventually find the overflow bug, but I've never gone back and made any changes or improvements. I just haven't had the time and enthusiasm to bother.

Well the thing is, with interpolation you're assuming that the intermediary values have a linear relationship to the sample points. With a wavelet or DCT system, you encode your data as the parameters to generate functions that fit the sample points. So instead of just guessing the middle, you guess whatever your function graph produces with the parameters you have available on decode. The problem is, if your function isn't a good match for your data, your quality/size ratio sucks, and it's more compute intenseive than just simple averaging.

I've got a compromise system design for this BTW, never implemented it.
