Hi, I've got the RTA-168B speaker test kit with a calibrated mic. I've done sweeps out of my speaker and white noise and I've gotten a spectrum that shows it's frequency response. I've also gotten a .fcf file from that and I've applied it to my spectrum analyzer as the 2nd compensation after the RTA.fcf file (of the calibrated Dayton mic) that's the first compensation. Then when I do another sweep or white noise test I can see the much flatter response in the spectrum analyser from the same speaker. So while I use that calibrated mic I've somewhat normalised the frequency response of the speaker as the spectrum analyzer displays it.
But I now want to play white noise or a frequency sweep to a solid state sound recorder that records to wav files and has it's own mic whose frequency response I don't know. Is there a way to change the signal generator so that the sound level at each frequency is the same and it normalises out the frequency response of the speaker that way so I've got the same SPL at each frequency to test the SD card sound recorder. Can I normalise the sound level at each frequency that comes out of the speaker or postprocess the recorded WAV file to it's like the speaker had a flat frequency response and I can then see the mic response on the SD card recorder.
