The speed of the adaptive LPC order search can likely be improved a good bit. Things to try:

Split search with direction threshold, similar to BGMC param search. Possibly only if order is above a certain value.
Progressive autocorrelation + levinson-durbin (probably won't work with split search though)

Still working on this, but I want to push more LPC changes upstream before complicating the code even more.
