>> I’m using 16000 Taps with a 8000 Tap Delay with a 48kHz Measurement and FIR export.
I’m curious – what processor are you using that can run 16000 tap filters?
>> So, Group Delay is expected at 166,66 ms.
Yes, assuming you are designing linear-phase filters. Note, FIR Designer can design arbitrary phase filters where the group delay can vary.
>> But I can’t use greater values than 100 ms in the GD plot window. Is there any solution to evaluate GD with filter Delays >100 ms?
Noted. It’s an arbitrary limit on the line edit box. We’ll raise the limit in the next update.
>> Second question is in regards of a lifetime license as an upgrade to my actual annual license fee?
See https://eclipseaudio.com/upgrades/
We can provide you with a discount coupon, towards FIR Designer M (Perpetual), equivalent to the value of the remaining months on your current annual subscription. Note: with a perpetual license the features are frozen at the version you purchase (e.g. 4.6). If you would like to proceed, email us at info (at) our website and we will arrange the coupon. (Your subscription license will be disabled after upgrading.)
