Exporting IR without HPF/LPF phase shifts

[xandde1]

Hi all,

I searched the forum before posting but couldn't quite find the answer I'm looking for (perhaps I'm using the wrong search terms).

I am using the Trace Arithmetic (A / B) function to export the resulting curve as an Impulse Response (.wav) to use in a convolution reverb plugin.

However, exporting the curve as IR introduces phase shifts at the extreme lows and highs, effectively acting as an unwanted High-Pass Filter (HPF) and Low-Pass Filter (LPF) in the phase response.

I'd like to exporte the pure IR without these band-limiting HPF/LPF phase alterations. Is there a way to export the exact Impulse Response as a WAV file without REW applying HPF/LPF?

Any guidance on the correct workflow for this would be greatly appreciated!

REW doesn't apply any filters to the export. If you are exporting the windowed response perhaps you are seeing the effect of your windows, but without any data to look at there's not much anyone can help with.
