Dear John,
i have noticed that You've added d&b audiotechnik filterset for export in the EQ window.
That made me wonder if similar implementation is possible for filter sections used by the industry leading amplified controller manufacturer - Powersoft.
In the Powersoft X8 amp (which i am most familiar with) there are three eq sections to work with:

input/grp EQ - up to 256 raised cosine filters

Speaker EQ - 8 IIR filters (any type) and two crossovers

And finally- output EQ - 16 IIR filters crossovers including predefined FIR highpass

Every of theese blocks has import/export feature. I attach also exported files from Armonia+ control software.


This full featured DSP serves not only for tuning complete systems like with the d&b filter set, but also for creating speaker presets from scratch. I think that adding this feature to REW would be awesome.
If REW would generate files compatible with the import feature of armonia+ it would be even more awesome.
Please tell me what You think about it.
Waiting forward to reading from You.

Magic.

d&b audiotechnik use a version of REW for their training courses. Equaliser implementations are mainly undertaken at the request of the manufacturer these days and would typically require internal information from them to be accurate.

what kind of information would You require?
it is higly possible for me to get that for You directly from the manufacturer.
i would be glad to help

What about equalizers for Realphones and SoundID Reference? I know a lot of people who could benefit from custom equalization for their headphones using the built-in EQ for these two applications. I tried doing it with the generic extended EQ but the bell shapes/bandwidth values are not equivalent. The sound was very different.
