We’ve added an ‘RMS-ACOUSTICS‘ IIR filter mode to FIR Designer (v4.1) & FIR Designer M (v4.1). It enables ‘WAY EQ’ IIR filter export for import into RMS-CONTROL software & aids mixed IIR+FIR RMS-ACOUSTICS preset creation.
IIR responses in the new RMS-ACOUSTICS IIR mode can be converted to/from Lake, Linea Research, Powersoft, Q-SYS, Symetrix, BSS, Biamp Tesira, Marani, RAM Audio & generic IIR modes using the IIR Reference Editor. (The ‘Generic’ mode is the a starting point for use with processors that don’t have their own branded mode.)
The IIR Reference Editor enables the automated conversion of IIR filters between brands in a single click. This ensures IIR response matching when working with different amplifiers & processors, and solves the problem of standard filter settings producing different results on various amplifier/processor brands.
Version 4.1 Project Compatability Notification
With the number of branded IIR filter modes continuing to increase, we’ve made an essential change to the project and system formats used within FIR Designer for IIR filter inclusion. This change will facilitate faster addition of even more branded IIR filter modes in the future. The file format change applies to both FIR Designer & FIR Designer M, from version 4.1 onwards.
This change means projects created in v4.1 (or later versions) aren’t backwards-compatible with version 4.0 and earlier. In addition, if projects created in earlier versions are opened in v4.1, we recommend saving as a new project (rather than saving over previous work) to avoid the risk of losing data.
