Auto-generated EQ filters show filters with 0 gain

[dima1stg]

Running latest version. Generated with "Match response to target", 60.6 hz and 103.5 hz filters are 0 gain.

Can you attach the mdat file? Is "Drop filters if gain is small" selected in the Equaliser preferences?

 

[dima1stg]

"Drop filters...." is off. Please see attached. Before generating filters, please select "miniDSP 2x4 HD" and set target level to 90 db. There is no room curve.

BTW, "miniDSP-96K" is always initially selected, even though in eq. preferences eq. is set to "miniDSP 2x4 HD".

Also, match range is 30-140, individual max boost 4db, overall max boost 0db, flatness target 3db, allow narrow filters and vary max Q both are on. Thanks.

If you select Drop small filters the zero gain filters will be removed. I'll make a change for the next 5.20.14 early access build so filters with zero gain are removed regardless.

The Equaliser preference is only applied for new measurements. Once a measurement has been made it remembers its equaliser selection and the selection can be changed in the EQ window. The measurement would need to be saved to make that change persistent.

Many thanks!

What is considered "small" for "Drop small filters"?

 

[thothsong]

It's stated in the Help on the Preferences panel:

If Drop filters if gain is small is selected any Automatic filters which have gain of magnitude less than half the flatness target at the end of the optimisation process will be freed up (their Type will be set to "None")

 

[dima1stg]

Even with "Drop filters if gain is small" on I'm getting 0 gain filters

 

[John Mulcahy]

With your original file or something else? Are you running the latest build?

 

[dima1stg]

Build is 5.20.13. Please see attached.

 

[dima1stg]

Flatness target is 3 db.

I suggest you try the latest build I linked.
