do you need an accurate fractional-sample-precision delay? that's how you tune a comb filter to a specific note.
How would you achieve a sub sample delay just in software without a filter? And consequently when using such a filter, why not performing the tuning directly therewith?
Which ciruit / dataflow do you see where such a combination works effectively?
Well we now about the issue when working with dedicated chips having a fixed comb filter included where such "pre processing" is requiered.
