I wanted to try this package on my DAM1941 assuming that the 1021 filters work here as well...welll...error message: "Incorrect Image" when trying to update...is there a pure NOS-Filterpack for 1941 ? IDeally with the first filter being NOS as my friend did not wanted to invest into the font-panel...so he has only one filter, the first one all the time.Finally readjusted allpass filter for hopefully satisfy wider group of people. It’s based on one of my early filter, so should be ok but verification is needed.
Some more explanation about allga filters family.
F4 to F6 filters stacks are made identically just with small change in FIR2 stage filter which is new 64 coefficient filter.This small difference allow to make adjustment of sound presentation according to preference.
Second thing that is special in allga family is magnified distortion adjustment with volume. If we set 0db on dac we could get over 5% THD. Lowering volume to c.a -6db on dac almost cancel that effect, so we have 0 to -6 db to adjust harmonics to preferred level.
There is FR with elevated high frequency ca 1.5db
F7 filter is NOS/NewNOS stack for “classical” presentation(volume level works as usually
Anti aliasing for all with IIR filters.
