Feature request: Number of taps on filter export

I'll add that to the todo list.

Did anything come of this? If so I must have missed it.

Oh I see. I tried this but it produced a silent filter, so I figured the answer must be something else. Basically, I am trying to get the pulse as close to the beginning of the file as possible so as to reduce the delay on my filter. It's just a basic minimum phase correction for my headphones, but there are 3 seconds of delay in the filter and I'm not sure how to handle it. When I export filters based on the auto eq function, they have virtually no latency. However, inverting the responses and exporting them as a filter is a different story - one I haven't spent any time with (in REW at least) yet. The IR Windows are showing 5000+ ms. I had taken my responses (B) and my target (A) and divided them (A/B) to get the inverted filter.

If your IR is minimum phase pick the "Place t=0 at sample index" option and set the index to zero.

The result of that operation is usually not minimum phase, you would need to make a minimum phase copy of the result.
