Version 4.3.5 (3 August 2024)

  • Various user-interface updates and fixes.

Version 4.3.4 (27 July 2024)

  • Updates to Auto IIR usability, including retaining settings between Auto IIR window closing and reopening.

Version 4.3.3 (22 July 2024)

  • New “Audio Weaver” IIR filter coefficient export.
  • Update to the loading of ETM and STO measurement files that have very long impulse responses.
  • Various UI fixes for problems introduced in version 4.3.0.

Version 4.3.2 (16 July 2024)

  • Fixes to UI problems with the StormAudio IIR filter mode.

Version 4.3.1 (14 July 2024)

  • UI Fix: FIR Designer normal (light) mode had display problems when running on Windows with the operating system mode set to dark.

Version 4.3.0 (12 July 2024)

  • New: FIR Designer now has a dark user interface theme available on both macOS and Window. To switch between light and dark themes, in Preferences, change the “Use dark mode” setting and restart the application.
  • New: The thickness of plot lines can now set in Preferences, from1 pixel to 10 pixels.
  • New: “AFMG SpeakerLab” IIR filter mode. (This mode is an analog filter mode and cannot be used with auditionDSP, nor exported to processors over DTP. It has simple, but not exact, conversion to/from other brands.)
  • New: “StormAudio” IIR filter mode.
  • Update: FIR latency compensation is now used on the Lab Gruppen DTP window (for export to IPX amplifiers).
  • Update: The “Supplementary Responses” window now has optional normalisation to a user-chosen response.
  • Update: When exporting FIR filters from the channel “Export” tab, two additional FIR filter files can be saved at the same time; a minimum-phase variant (with 0 sample delay and the same length as the main FIR filter) and an excess phase variant (with the same delay and length as the main FIR filter). The convolution of these two additional FIR filters matches the magnitude and phase of the main FIR filter. The enable this feature, press Control-H and a checkbox appears, labelled “Also save minimum and excess phase FIRs.”
  • Various UI updates and fixes.

Version 4.2.7 (13 May 2024)

  • Additional fix: In the “Generic” IIR filter mode, the Elliptical HPF and LPF stop-band gain value couldn’t be edited. (Bug introduced in version 4.1.)
