[Interest] How to properly show progress for a signal processing pipeline

And because the A->B->Final portion of the pipeline takes a noticeable amount of time, I can't just run the progress bar from 0 to Raw count, because then from the user's standpoint the progress bar would reach 100% once the number of raw samples is exhausted, not when processing is fully complete.

You could show three progress bars, one for each stage.
Assume each item will pass through each stage (which is pessimistic)
and show progress based on that. In most cases the whole
process will finish early based on the bars, but progress
will be shown.
