frd

I am making gated measurements of individual drivers mounted in the loudspeaker enclosure at a distance of 1 meter. I am using a UMIK-1 with its calibration file and also a seperate tweeter as an acoustic timing reference. My goal is to export SPL and MINIMUM PHASE measurements of individual...

I've been out of tuning for about a year and now would like to tune my cars audio system. I have forgotten how to get REW to recognize the .frd calibration file from CSL. Could anyone shed some light on this?

To use Passive Crossover Designer (or the Windows version, WinPCD) requires that you import the speaker frequency response as an .frd file or the impedance curve as a .zma file. The instructions for REW explain how to export your measurements as text files and state that the format is compatible...

I've used REW to export minimum phase impulse (.wav) files, but it would nice to directly export minimum phase .frd files the same way. I can't find a way to do that except to export a min-phase IR, read it back in and write that out as an .frd file. Am I missing something? Thanks, Ed PS -...
