This is only for the 96khz platforms. Only the subEQ filter will have 3Q limits below 50hz. If they make the proposed change of letting peak go back down to 10, instead of being limited to 50, it should make everyone happy.

Dear all,

A new Beta is now posted without any frequency limitation on the Peaking EQ (down to 10Hz). Hoping it fits everybody's needs by having the option to use SubEQ or not... For those who don't need it and didn't want anything changed in the first place, it's back to business as usual. :-)

Have fun,

Thanks.

This should go a long way ;)

I take it a subeq option for high/low shelf filters, like for the peak filter, would be too hard to do?

At this point of time, it's not known if the same technique applied for the PEAK filter would be possible on the shelf.. Maybe we can see in the future.

I'd appreciate a fix for the shelf filter, I use it to EQ sealed subs.

Cheers!

Interesting topic! Raises the question for other miniDSP users too, to seperate "possible realworld frequencies" from "technically impossibbly odd measurements that apparently are possible :)".

Ultra low frequencies cannot be heard by a human ear. They can be felt by the human guts ever so :kiss: And since music for me is all about a feeling, ultra low frequencies do make sence.

@devteam, you say the graphs are odd, since 2hz is just technically impossible. So what are more realistic lowest measured Hz on the 2X4 miniDSP? 10Hz? 15Hz? 25Hz? where the rolloff starts to drop too many dB?

Same question on the right side of the graph: 18Khz? 23kHz? 30Khz?

PS The advanced realworld realistic measurements you have @devteam I am sure non of us possesses so I trust the data from you the most @devteam. A graph for the 2X8 and 2X4 would be very nice! If I ever want to upgrade to a 96Khz 2x8 then your graph and an extended frequency range measured in real world not just theoretically, would be reason enough!

I myself also adore the ultra low frequencies that a human ear cannot hear, but a human belly will definately feel! And since music for me is all about a feeling, ultra low frequencies <em>do</em> make sence.

It's good down to about 5hz, anyway, might want to read the entire thread as it played out. They added a special filter to work under 25hz for peak due to the bug, but it would be nice to have one for low and high shelf also.

@Nyt thanks, yes i did read the entire topic, but perhaps, no... definately, I am no way as experienced as the devteam or as you ;)

Did you mean 5hz for the 2X8 only, or also for the 2x4 miniDSP revB?

I did not notice the extra option in the adobe air programm? perhaps thats still a beta and not yet in the main program?

Kind greetings from HOlland

Hi,

Any possible news on this? Thanks.

Unfortunately, no progress on this as we've been tied up upgrading some firmware for the IR feature and preparing some upcoming product release. The SubPeak Equation having taken a lot of engineering time and resources to achieve it, it's no simple task by any means I'm afraid.

Hoping we can find some time in the near future

Thanks for the update! Glad it hasn't been forgotten about. Hopefully the previous work makes it easier to do the other filter types.

I have the 2x4 with 2-way XO advanced, and I need HP filtering at 14 Hz.

Are any of the ways to do this (shelf filter in PEQ or HP filter in the Crossover section) affected by this issue?
