How to process externally generated FIR filters?

[jlwehle]

quantization_tests.cpp shows how to optimize the coefficients of a FIR filter synthesize by fquantizer.

Is there a way to optimize the coefficients of a FIR filter synthesize by another program?

Unfortunately fquantizer fails to synthesize the filter specification I'm working with, however GNU Octave fir2 is able to successfully synthesize the filter. So I have the specification (meaning frequency bands and magnitudes) as well the the floating point coefficients generated by GNU Octave fir2 .. I wish to generate an optimized set of integer coefficients.

Can this be done using fquantizer?

Looking it testLatticeBasedQuantization I see outputD.x is being used ... it's not clear to me how to provide that information.

Hmm, not yet. I should be able to add this functionality. I first have to take care of the other issues first, though. Hope to get to it soon.

Just curious about any plans to revisit this issue.
