    Hello,
    I have measured impulse response with soundcard and mic calibration files. I see impulse on display compensated for soundcard and mic. But i can't
    export this what i see. If i export to .wav file, rew discards my compensation files. Why is that? Maybe bug?
    I have to convolve my exported file later with soundcard/mic calibration files:(

    Regards,
    Rytis

    Calibration files are only applied to frequency responses, not to the impulse response, mainly to avoid boosting noise in the impulse response in regions the cal files have attenuation but also to make it easier to change or remove the cal files later.

    I'll add an item on my todo list to make a trace arithmetic operation which merges the cal data for a measurement into the IR. Note that you can do convolution in REW using the trace arithmetic features of the All SPL graph.
