When I export a measurement's impulse response as wav, the high frequencies (10kHz -- 20kHz) are quite heavily reduced (-10dB on the afore-mentioned range). This can be seen when re-importing the impulse response into REW.
It came to my attention by using the FIR filter calculator named porc. It uses the impulse response as input, and, because of the high-frequency dip, the correction is suddenly +10dB at 20kHz. Which is not desirable.
Is this a "natural" behavior of impulse responses exports that the FIR filter calculator should be aware of, or can this be corrected with respect to the REW export ?
As an example, please find attached some measurements showing this inaccuracy.
