FIR Designer 2.2 – New Gain, Polarity & Delay Functions

FIR Designer 2.2 – New Gain, Polarity & Delay Functions

posted in: FIR Designer | 0

Today’s release of FIR Designer v2.2 includes the addition of a new Gain/Polarity/Delay tab and Summary output file. It provides everything needed for a complete loudspeaker DSP channel signal chain.

The new features are simple to use: after measurement import, use the new tab to set parameters for gain, polarity & domain. Then proceed through the workflow as normal to set IIR filters & create the FIR filter. At the ‘export’ stage, choose the new ‘Save FIR + Summary’ button to create TWO files – the (usual) FIR filter file PLUS a new summary text file. Take a look at this video to see how it works.

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

Existing FIR Designer 1 license-holders are eligible for a USD $100 coupon towards the first-year purchase of FIR Designer 2.2; just contact us.

Complementary Linear Phase Crossovers in FIR Designer

posted in: Uncategorized | 0

Unlike common Linkwitz-Riley filters, many other HP & LP crossover filters don’t sum to unity or have matched phase. For a perfectly flat summed response, FIR Designer can calculate a COMPLEMENTARY HP (or LP) filter from the chosen LP (or HP) filter, when set to linear-phase. The filter pair can be used for targets in multi-way designs, providing more crossover options. Works for Bessel, Butterworth, Chebyshev I & II & Elliptic filter prototypes. (FIR Designer also has a variety of linear-phase brick-wall crossover filters.)

FIR Designer 2.1.2 UPDATE FOR SMAART USERS

posted in: Uncategorized | 0

Smaart Trace (TRF) files with a specific FFT size can now be loaded into FIR Designer or FIR Creator (previously only MTW based Trace files were accepted). V2 license holders: check your email for a link to download the latest version. (BTW, FIR Designer 1.31.7 includes same update).

 

FIR Creator 1.1

posted in: FIR Designer | 0

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 at www.eclipseaudio.com/fir-creator.

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).

New feature for FIR Designer 2: ‘Second View’

posted in: FIR Designer | 0

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. Second View saves time in the filter design process.
