Hello,
I will first introduce myself: I am Jan Jaap Derksen from the netherlands. As hobby i am building professional audio speaker systems for bands or other events. (when covid 19 is gone....) I am using REW with the umik-1 mic till now just as indication of the frequency responce of the speaker and adapt the EQ manualy in the system.
i am struggeling with a problem in REW..The measurement of the speaker i can import into the DSP of my new amps to use FIR-eq. But the problem is this system can only handle linear line frequency responce.
When i am exporting a measurement as text file i cant find (or is not possibol) to export the frequency lines linear.
Accourding the dsp manual the file should like this:
FFT degree: 14
Sampling rate: 96 kHz
Samples in time domain: 16384
Lines in frequency domain: 8193 (0 Hz … 48kHz)
Line distance: 5,859375 Hz
File entries
Freq[Hz] Real[Pa] Imag[Pa]
0.000000E+00 0.000000E+00 -2.526122E-10
5.859375E+00 0.000000E+00 1.192093E-07
1.171875E+01 6.837189E-03 - 9.961390E-02
…
…
4.798828E+04 -1.115020E+00 -1.757477E+00
4.799414E+04 1.508967E+00 -2.896538E+00
4.800000E+04 -4.855079E+00 2.351044E-10…
Is there a way to get this work? Or is it possibol due to update of the software to get this kind of exports?
Thanks in advance
