The recent updates to FIR Designer & FIR Designer M go beyond the new dark interface.
We’ve introduced two new branded IIR modes – AFMG and Storm Audio – to ensure precise matching of the IIR filter behavior with the destination processor by adjusting for brand-specific differences in IIR filter interpretation. The AFMG mode is unique in modelling analog filters spec’d in loudspeaker GLLs used in AFMG simulation tools like EASE and EASE Focus.
Two new export options are also available. These include an IIR filter coefficient export option specifically for Audio Weaver (adding to the existing FIR export capability), and Direct-to-Processor export for Lab Gruppen’s IPX range of DSP amplifiers (read IPX loading instructions).
Users of FIR Designer’s ‘Supplementary Responses View’ will welcome the newly-added normalization option. A new set of loaded measurements can now be viewed in relation to the on-axis response, for both individual response plots and the polar heatmap, providing a clearer picture of the loudspeaker’s radiation pattern. All main workflow processing – gain, polarity, delay, IIR, FIR – is applied to the new measurements before on-axis normalisation is applied.
