I am running the current 1.2.0 version under Win 10 and have managed to successfully create filters for a commercial sound project using BSS processors and Crown amps. Both support .csv, .dat format files.
I have not been able to get any display of phase response curves at all beyond the dotted 0 phase line and have not been able to sucessfully use the phase correction tools. Other than that everything seems to work fine.

Please help.
thanks,

Razz

Hello Razz,

Sorry but I don't understand what you mean by "display of phase" here.
You mean inside rephase?
Do you import a measurement? Does that measurement include a phase column?
download the last version of rephase here: rephase.org

I am importing a deconvolved impulse response file from the Audiotools Larsa module sine sweep.
I have the full Audio tools suite plus Easera Systune.
Perhaps I need to run a different impulse response test?
What do you recommend?
The zero phase line is present and filter adjustments show before I import a test file. But only the zero phase line shows after. No phase data from the test file apparently.
Like the program, But I am definitely on a learning curve here. Trying to write a replacement for an EAW QX series fir file that they only provde in a binary format not supported by BSS/Crown DSP's.
Thanks for responding

I don't know this software suit you are using so I cannot help you there, but it looks like it only exports a magnitude curve, which would explain why rephase does not show a phase curve.
rePhase does not import measurement impulses per se, it imports measurements curves as 3 columns frequency/magnitude/phase. Compared to an impulse this gives the option to apply gating/smoothing as well as time offset inside the measuring software.
You can open your measurement file in a text editor and check if the 3rd column is missing.

REW and HOLM Impulse, among other free software, can be used to export 3 column measurements if your software cannot.

The Audiotools module that works with Rephase is the Transfer function module. It produces the right kind of data files to import directly into Rephase unmodified. studiosixdigital.com/audiotools-modules-...s/transfer-function/
I am working with commercial large venue systems that are designed for high output and well defined pattern control out of compact enclosures rather than smooth response like a hi-fi speaker. They have some pretty nasty phase characteristics uncorrected. Conventional EQ techniques just don't get the results needed. Manufacturers develop custom FIR filters for systems like this, but some only provide them in proprietary binary formats that work with their corporate brand electronics.
Nice to find a work around that can produce acceptable results with a user friendly interface. I'll contribute a few bucks to the cause when I get caught up.

Thanks POS
