Faster LU filters?

[wlangfor@uoguelph.ca]

So, I was working with LU and using it practically apply it to sound; and it only works for overall, but when using it to apply to crossover sections it starts to lag, especially in bass.

Is there any hope of making a faster LU detection? The one I got together with MV's TDF2's works great, but the question is whether or not there is any faster.

Here is the link to the LU testing stuff I put together. I used some of Youlean's pointers and it's faster than his original, but not fast enough i guess. If there were somehow less filtering, it might still be possible.

what is LU?

Loudness Units, it uses a c-weight filter and sometimes double precision to decide dB with less emphasis on bass and treble. The combination of weighting and style is referred to as K-weighting, designed by Bob Katz.

It's a european and broadcasting standard throughout the world. The only issue is that the filter to decide the volume is a bit slower than real-time. But only by a very small margin. It could potentially be optimized. But I am unsure how as yet; but will try.
