New FIR Creator EX shares FIR Designer’s advanced export options

by | posted in: FIR Designer | 0

A new, standalone version of FIR Creator is now available: FIR Creator EX offers the same advanced export options found in FIR Designer, including the brand-new Direct-To-Processor functionality for integration with Lake & Powersoft amplifiers. It will be priced at a one-off cost of USD$299+tax (vs. FIR Creator @USD$249+tax). Unlike the mostly static feature set of FIR Creator, FIR Creator EX will be updated as necessary to incorporate any new DTP integrations developed between FIR Designer & other brands (ie. in addition to Lake & Powersoft). However, beyond updating DTP functionality, FIR Creator EX won’t receive updates (apart from essential bug fixes), as our development efforts continue to be focused on the subscription-based FIR Designer.

See the Product Comparison Table to compare features of FIR Creator, FIR Creator EX & FIR Designer

The specific additions to FIR Creator EX (vs. FIR Creator) are as follows:

  • Two additional FIR Filter sample rates: 12 and 24 kHz (FIR Creator has 44.1, 48 & 96 kHz)
  • Three additional Export formats: Powersoft, Linea Research & EV/Dynacord (FIR Creator has text [inc. CSV], Binary & WAV) 
  • Processor gain, polarity & delay settings (not available in FIR Creator)
  • Processor channel summary setting export (not available in FIR Creator)
  • Direct-to-processor functionality (not available in FIR Creator):
    • To LAKE PLM, PLM+ & D series amplifiers. Requires the FIR Designer LAKE plugin and the LAKE FIR 3-way module, & works over a (fixed or wifi) network.
    • To Powersoft X, Ottocanali, Quattrocanali and DueCanali series amplifiers. Works via an XML file which can be loaded into the amplifier’s “Speaker EQ” or “Output EQ”.
    • Can optionally side-load pre-existing FIR filters (with sample-rate-conversion, if necessary) from other programs for transfer to LAKE &/or Powersoft (subject to their FIR tap limits).

FIR Designer 2.4 – New Direct-To-Processor Function for Powersoft

by | posted in: FIR Designer | 0

FIR Designer 2.4 now integrates with Powersoft amplifiers. Transfer a DSP signal chain directly from FIR Designer to Armonía for use in Powersoft amplifiers via our new DTP (Direct-To-Processor) functionality. Pre-existing FIR filters (from sources other than FIR Designer) can also be loaded – with or without resampling – and transferred in combination with FIR Designer’s IIRs, gain, delay and polarity settings.

DTP for Powersoft works via an XML file which can be loaded into the “Speaker EQ” or “Output EQ” on X, Ottocanali, Quattrocanali and DueCanali series amplifiers.

Powersoft is the second brand to offer close integration with FIR Designer (LabGruppen LAKE PLM, PLM+ & D series amplifier integration was released in FIRd v2.3). We’re hoping to provide direct integration with other amp/processor brands in the near future. In the meantime, FIR Designer can export data in a variety of formats for subsequent upload into most FIR-capable productsWe’d love your feedback: Which amplifier brands would you most like to see facilitating direct-to-processor FIR Filters/DSP chains from FIR Designer? Tell us here.

For more details on v2.4, see the Release Notes.

FIR Designer 2.3 – New Direct-To-Processor Function for LAKE

by | posted in: FIR Designer | 0

FIR Designer now integrates with LAKE PLM & D series amplifiers. Push a complete DSP signal chain directly from FIR Designer to the LAKE FIR 3-way module via our new DTP (Direct-To-Processor) functionality. Watch the video here. Pre-existing FIR filters (from sources other than FIR Designer) can also be pushed – with or without resampling – in combination with FIR Designer’s IIRs, gain, delay and polarity settings.

DTP works locally – over either a fixed network or WiFi – with a new LAKE Controller plugin (supplied in the FIR Designer 2.3.0 Windows installer). Data transfer takes only a few clicks.

We’re hoping to provide direct integration with other amp/processor brands in the near future. In the meantime, FIR Designer can export data in a variety of formats for subsequent upload into most FIR-capable products.

Shaping Loudspeaker Phase

Shaping Loudspeaker Phase

by | posted in: FIR Designer | 0

FIR filtering offers advantages over traditional IIR all-pass filters when flattening the phase of a loudspeaker or shaping the phase to match others in an installation. IIR filters have a negative phase gradient & only provide time delay with increasing frequency. However, FIR filtering can implement phase responses with both positive & negative gradients, providing arbitrary phase/time shaping of a loudspeaker response.

FIR Designer offers traditional 1st & 2nd order minimum-phase all-pass filter prototypes, plus maximum-phase (inverted phase) versions & a unique 4th order parametric phase filter with a range of ±90 degrees, adjustable BW & frequency. An unlimited number of prototypes can be used to create the combined FIR filter phase response.

Complementary Linear Phase Crossovers in FIR Designer

by | 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

by | 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

by | 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’

by | 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.
