FIR Creator Sample Rate Options

In response to feedback – especially from MiniDSP users – FIR Creator v1.1 now includes a 96 kHz sample rate option (in addition to 44.1 & 48). Full specs here.

FIR Creator 1.1 also includes new accelerated FFT’s, which are roughly 4x faster than the FFT’s in the original version 1. Every UI change triggers many 10’s of double-precision transforms so these updates translate into faster screen refreshing during filter design (the latest version of FIR Designer also includes this speed improvement).

FIR Designer 2.1 – Continuous Wavelet Transform View

Today’s release of FIR Designer v2.1 includes a major new feature – a Continuous Wavelet Transform view

  • See a time/frequency map of the loudspeaker impulse response, with or without filtering.
  • Loudspeaker wavelet displays in “Second View” window (recently introduced with v2.0)
  • Updates in real time due to a unique, efficient implementation; instantly see the impact of changes made elsewhere in the workflow.
  • Includes adjustable wavelet width & view scaling.

To see all updates for v2.1, see the Release Notes

New feature: FIR Designer ‘Second View’

The newly-updated FIR Designer 2 has a new feature called ‘Second View’. It shows an additional window for any workflow plot, which can be viewed on the primary display or on a different monitor/display. Do your edits & see the impact on whatever part of the workflow you choose, in real-time. FIR Designer’s Second View saves time in the filter design process.

FIR Designer & FIR Creator are FIR Filter designers

[2019 Update: Build a complete loudspeaker preset for multiple channels simultaneously with the new FIR Designer M].

FIR Designer, the intuitive FIR filter design tool for loudspeakers, is evolving into TWO software tools – FIR Designer 2 and FIR Creator – to better meet the FIR filter design needs of manufacturers, installers, consultants & enthusiasts. Existing license-holders can keep using FIR Designer 1, although there will be no more feature updates (just bug fixes). We’re offering a USD $100 coupon to any existing FIR Designer 1 licensee who’d like to switch to FIR Designer 2.

Check out the table we’ve put together to compare all FIR filter designer products. FIR Creator is a pared-down option available for a one-off cost of USD $249 +tax. It will also be supported with bug fixes as needed. FIR Designer 2 is a fully-featured product offered as a USD $399+tax annual subscription [2019 Update: Price for FIR Designer is now $299. FIR Designer M costs $399]. FIR Designer 2 provides extensive functionality, flexibility and compatibility. Ongoing development & regular updates will ensure the latest advances in FIR filter design are always available to businesses.

FIR Designer 1.31

Much has happened since the last post. Exporting now includes support for Linea Research products. Filter types have been expanded to include Neville Thiele notched crossovers (NTnc), Chebyshev and Elliptic high-pass and low-pass filters. Also plots now include zooming, a thicker plot-lines options, on/off for any plot trace and a Step Response view on the Export tab. For more details, check out the Release Notes page.

FIR Designer 1.25

For EV and Dynacord processor users, version 1.25 can export FIR filters as GKF files for loading through IRIS. Plus, there are five new linear-phase brick-wall crossover filter prototypes, and constant Q when the editing is set to Q in Preferences. For more details, check out the Release Notes page.

FIR Designer 1.22

Version 1.22 has many new features since the last 1.15 post. Measurement averaging, multi-window, import measurement smoothing, complement filters in Direct Design, IIR all-pass filters and IIR coefficient export, speed improvements, EASERA EFR file support and lots of UI improvements and bug fixes. For more details, check out the Release Notes page.

Danley & FIR Designer Bring Coherent Sound to Pacific Hills High School

Pacific Hills Christian School in Dural, New South Wales, recently upgraded from their multi-purpose hall’s 20 year old, mostly voice oriented PA, to a multi-zone Danley Sound system capable of handling concerts and musical productions for an audience of over 1300. “FIR Designer” software from Eclipse Audio was used to create custom FIR filters for the different models of Danley loudspeakers (each with different phase responses), resulting in improved coverage consistency and intelligibility. Read the full article from CX Magazine here.


FIR Designer 1.15

Version 1.15 has big improvements in usability and some helpful new features. After many requests, a new “Voicing” EQ tab follows after the auto-mag and auto-phase processes. The “Auto Phase” tab now has more than one frequency band. In fact, now there is no limit to the number of magnitude and phase filters, auto-mag and auto-phase frequency bands, and target slope segments. (Add, delete and re-order the filters, bands and segments at will.) Also, shelf and bandpass filters are now available on the “IIR Filters” tab, and the frequency range of the max/min error calculation, on the “Total Error” plots, is now user definable.

FIR Designer 1.10

Version 1.10 has a raft of new features and updates. 192 kHz filters can now be created. We’re asking for feedback on a new Measurement Averaging tab where a directory of measurements can be loaded, time/phase aligned, and averaged using one of four different methods. Longer filters – now out to 65536 samples – can be generated. Also the import process for time-sample based measurements has be revamped to better support creating filters for multi-way speakers and support using linear phase FIR filters as target responses. For more details, check out the Release Notes page.
