FIR Designer M is an advanced & comprehensive software tool for creating custom loudspeaker processing (IIR+FIR) and complete multichannel presets.

The version 4 major update adds ‘auditionDSP’ – a dynamic new digital signal processor & audio player. It enables users to listen to their custom processing during the development process, rather than relying solely on visual plots.

auditionDSP also allows different filtering options to be audibly compared by running processing for up to three loudspeaker presets simultaneously, in real-time, with live switching between presets. “Filters and presets can be perfected quickly, without the need to first export data to an external hardware processor for playback,” said Michael John, lead developer at Eclipse Audio. “This is invaluable when time is tight, such as during live sound installs.”

Audio input for filtered playback via auditionDSP can be either live, or from a loaded WAV file, to suit the needs of different users. “We’ve got a range of audio professionals using FIR Designer, like installers, loudspeaker manufacturers, A/V integrators, touring system engineers, acoustic consultants & audio rental companies,” said John. “Since FIR Designer M is so multi-functional, users typically adopt their own sub-set of features & functions for regular use. But based on beta feedback, we think all of our users will find auditionDSP a valuable addition to their workflow. Who wouldn’t want to listen to their work during the design process?”

The FIR Designer M v4 update also adds a range of other new features & functionality, such as a Contour Plot for off-axis analysis, a Group Delay display, project-specific plot colour customization, upgraded macOS support (for M1 & M2 based macs) & significant computational speedups for faster UI response. In addition, a new ‘RAM Audio’ IIR filter mode has been added to the list of emulated brands, joining Lake, Linea Research, Powersoft, QSC Q-SYS, Symetrix, BSS, Biamp Tesira & Marani. (A ‘Generic’ mode remains available as a starting point for use with processors that don’t have their own branded mode.)

“Several of the new features were developed in response to user requests,” said John. “The version 4 update is the biggest single leap forward in functionality for FIR Designer M since its debut in 2018.”
