So how would one export it? The only way I could think of was going to the EQ tab and generating "filters" which are meant to be the inverse of the EQ so as to noise cancel it. The only problem with this is the EQ curve you get or the harmonic distortion data isn't in a form that I can put into a plugin, not even text data that represents that EQ. Subsequently, use the arithmetic function of A/B to get the difference since they are logarithmic and use db. Now, trying to get the difference between the two mics, or even two mic pres is done by measuring one and then the other. It makes that reference mic the "0" so it knows any changes in EQ can be credited to the room. In REW you can use mic calibration files, meant to obtain room acoustic impulse responses using a measurement mic like an ecm8000. I put the microphones as close to the same position as possible so, as you have said, remove the variables of the room. I was obtaining impulse data in REW using a log sweep. ReaFIR in subtraction mode would be able to do something like this somehow also, but I think deconvolution is the right way to go. IDK how much difference it will actually make, but it can't be none. When you recorded the original files, was it driven by a file containing a sample of noise or a random noise generator? You'll need to do it with the file. I think you also need to have started with the same noise, though. I tend to think that you'd want both files exactly the same length, starting at exactly the same time. My only real question is how to prepare the files first. Pretty sure ReaVerb (free with Reaper) can do both the convolution and the deconvolution. I think that if you deconvolve one with the other, you should end up with an IR file that you can load into whatever convolution plug you want. So you've got what? A pair of wav files where you ran noise through your pres and recorded the output? The reason why is kind of obvious but not easy to explain, so I'll let you google for it. Impulse responses can't really reproduce non-linear aspects like distortion. I am able to use those frequency responses to Ed a track now if I want which is nice (of course it does not allow me measure the harmonic distortion of the preamp or to accurately measure the difference of a mic).ġ) How can I obtain EQ data that reflects the difference between my microphones which can be used as an EQ setting?Ģ) How do I export it? Which plugin can I import it with?ģ) Is there any other data which may be useful (that can be found in REW or the likes) when comparing two mics such as octave distortions that I can also import into a plugin? I have used q-capture and q-clone to obtain the frequency response of my preamps to see how they are impacting my sound. Is it possible to calibrate REW with one mic (such as an AKG c414b-uls) instead of calibrating with the measurement mic (flat frequency response mic, such as the ecm8000) and then run a measurement of a second mic (like a c414 xls) to determine what the difference in frequency response is? Can I export the eq data to import into a plugin in Cubase? I am wondering how I can go about using a program such as Room EQ Wizard to find the difference in EQ between two microphones and export the eq data file to be imported into a plugin within a DAW such as Cubase 8. I've done a search and cannot seem to find a post or reply which answers my question.
