Version 1.3.2 (13 July 2019)

  • Fix: Filename in title bar might not display correctly.
  • Update: Solo checkboxes cleared and tab Enable checkboxes enabled after program load.

Project File Format Version: 19


Version 1.3.1 (11 July 2019)

  • Various user-interface updates and fixes.

Project File Format Version: 19

Version 1.3.0 (9 June 2019)

  • New: FIR filter “rewindowing” when sideloading. On Lake and Powersoft DTP dialogs, sideloaded FIR filters longer than the platform supported FIR filter length can be shortened and optimised using a new “rewindowing” dialog.
  • New: Phase plots no longer show a vertical line at the wrap point. (The old plot method, that shows the wrap line, can be enabled in Preferences.)
  • New: IIR filter modes provides accurate emulation of IIR filters for specific brand products, particularly with regard to bandwidth or Q. Options include “General” (including all IIR filters from prior versions of FIR Designer), “Linea Research” (including unique Hardman crossover filters) and “Powersoft.”
  • New: FRD measurement file, SMAART SRF file and miniDSP BIN (32bit float) file import.
  • New: FIR file, and 32bit and 64bit float FIR filter file export for DFM processors.
  • New: FIR text note for GKF files on export.
  • Fix: Magnitude offset level not correct when importing some SMAART TRF files.
  • Fix: Program crash when trying to load an AFMG SPK file.
  • Fix: Some WAV files from realtime recorders may not load and cause the program to crash.
  • Various user-interface updates and fixes.

Project File Format Version: 19

Version 1.2.5 (3 April 2019)

  • Fix: Some WAV files, generated by SMAART, wouldn’t load.
  • Fix: When resampling an impulse response during load, some sample rate combinations caused artefacts.
  • Various user-interface updates and fixes.

Project File Format Version: 18

Version 1.2.4 (20 January 2019)

  • Minor update to the tracking of odd-order low-pass Bessel filters. (See fix in 1.2.3.)

Project File Format Version: 18

Version 1.2.3 (17 January 2019)

  • Fix: Polarity of odd-order low-pass Bessel filters was incorrect, but matched Lake products. This version calculates the correct polarity for new projects, but maintains the inverted filters when loading older projects. It also provides an option to convert a project to the correct polarity.
  • Various user-interface updates and fixes.

Project File Format Version: 18

Version 1.2.2 (25 November 2018)

  • Various user-interface updates and fixes.

Project File Format Version: 18

Version 1.2.1 (4 November 2018)

  • Fix: A power spectrum only STO file may crash the application.
  • Fix: The FFT size, for new projects, in the Preferences dialog wasn’t saved between program runs. (Bug introduced in 1.2.0)

Project File Format Version: 18

Version 1.2.0 (2 November 2018)

  • Update: Improved robustness of network communication with the Lake Controller plugin for some rare situations.
  • Fix: When side-loading FIR filters on the Lake and Powersoft DTP dialogs, some FIR filters that should load were being prevented and were triggering a message that they were too long. The FIR filter length check wasn’t adjusting for the difference in sample rate between the FIR filter and the output channel.
  • Various user-interface updates and fixes including parameter table drop-down controls now open in one click.

Project File Format Version: 18

Version 1.1.0 (29 July 2018)

  • New: “Monkey Forest” SPK measurement files can now be loaded.
  • New: When “Normalise magnitude to max” is set, the “Magnitude offset (dB)” field displays the normalisation gain.
  • New: Right-clicking on a zoomed plot now zooms out to maximum.
  • Fix: Minor error in measurement response when measurement is resampled down to 12 kHz or 24 kHz.
  • Various user-interface updates and fixes.

Project File Format Version: 18

Version 1.0.1 (28 April 2018)

  • New: A direct link to the new version is now provided on the update dialog.
  • New: Added Klippel Impulse Response text file measurement loading.
  • Fix: When loading TXT and WAV files, if the delay is indicated in the filename, it wasn’t being used correctly to align the measurement.
  • Various user-interface updates and fixes.

Project File Format Version: 18

Version 1.0.0 (21 April 2018)
