Audio Amplifier / Sound Card Calibration Files

[Mallick]

We are inputting the calibration file for the REW but what about the amplifier calibration, is it not necessary when using it for acoustic measurement?

Some maybe using a chip based amplifiers with both ends tapering down in frequency response with phase shifts.

Of course we can put the amplifier in the chain when we calibrate the sound card, won't it be nice to have a separate file for this?

I could not find any topic on this subject in the forum

This is the solution if the effect of the amp's bandwidth limits is significant.

Good afternoon!
is it possible to make restrictions in the calibration of the sound card by frequency?
for example, when my sound card works in 96k, the calibration occurs from zero to 48kHz and then on many cards I see artifacts, the same when in 48k mode the calibration of the card occurs at 24kHz. I am forced to make measurements without calibration and mathematically compensate with the recorded loop measurement of the card in 96k with the start of measurements at 10Hz and up to 22kHz then I have no artifacts of the AD conversion
