Hi Andrew

Sorry for the delay, but you are in good hands here :)denver8me4dinner wrote:
I noticed that once I go past a certain number of taps the fft length changes. Example diffrance between 511 taps and 512 taps changes the fft length to next size block.

With that said, obviously a longer fft uses more taps, so would you know if using the horn and sub 1 tap below the next size block make it more efficient?

The longer the FFT the more precise the visualization gets down low, but the final impulse remain the same.
Optimization can also benefit from a longer fft in some corner cases, but the minimum values are already enough most of the time.

Oh, and of course, the longer the FFT the longer the generation time...
It also seems like filter linearization uses less taps than making the filter in the Fir, is that so?
This is indeed the case, for reasons that i don't have the courage to explain right here right now :p
