FIR filters design software

Been wondering if anyone could recommend any decent software to design FIR filters. I've been using RePhase still learning how to use it and it works ok. One thing I'm missing is to be able to adjust phase only. It would be very useful for sub filters.

I've also downloaded FIR Designer which looks better but I cannot test without paying $100 for the licence. Anyone had any experiences with these two or any other?

For my personal use I need something that can work with my Minidsp OpenDRC-DA8 that allows max 2048 taps per channel at 48kHz or about half that at 96kHz. Happy to discuss other solutions for other people's benefits here as well.

Rephase can adjust the phase only. It's in the eq part.

Thanks Edd.

Will have a look tomorrow. So far every time I've tried it also adjusted magnitude which isn't what I'm after.

You can definitely adjust phase and amplitude independently of each other with Rephase.

Its the paragraphic phase eq tab.

Thank you, both!

It may have something to do with the fact that my EQ type drop down boxes are both greyed out on Phase EQ tab :( I'll do more digging and see if I can do it. Maybe download another version.

The drop down boxes are for normal EQ, for selecting minimum or linear phase, you don't need that for just adjusting the phase.

I've done phase only adjustments with rephase and DRC designer.

When using DRC designer; If you max out the target response to flat at 0db and then limit the gain adjustment to 0db, the software will just create phase only correction filters without being able to alter the amplitude.  This option may be little use if you want to use a single filter with a mix of phase and phase/amplitude adjustment because of the automation.
