First, on FIR Designer’s Export tab, save the filter in the format required by the audio processor. Then load the file into the manufacturer’s control software. (Exact format & loading procedure varies between brands, so check the product-specific info above or refer to the control software instructions supplied by the manufacturer.)

For some DSP platforms, FIR filters can be transferred as part of a complete loudspeaker preset via the Direct-To-Processor (DTP) functionality, bypassing the manual export & loading process. Learn more about DTP.

The required FIR filter file format depends on the destination processor and its control software. While some brands accept CSV, TXT, WAV & BIN files, others have proprietary file formats. Filters designed in FIR Designer can be exported in any of these formats. Check the audio DSP brands above to identify the appropriate format for your device.

Not all processors & amplifiers support user-loaded FIR filters. Some don’t support FIR filtering, and others have built-in FIR processing that can’t be modified or overwritten by users. To load a FIR filter created in FIR Designer, the processor must support user-loaded FIR filters and the filter must be in a compatible file format for loading into the processor’s control software.

Check the brand control software information above for known FIR loading requirements and export formats. Keep in mind that within a single brand, some devices may accept FIR filters while others don’t.

If your processor doesn’t allow users to load their own FIR filters, you can still use FIR Designer to create IIR-based EQ for the device, as most pro audio DSP devices have user-accessible IIR settings. Use the IIR Filters tab in FIR Designer to choose from a wide range of built-in IIR filter types, including brand-specific options, using uploaded loudspeaker measurements as the basis for filter design.

If you already have a FIR-based EQ design, its possible to recreate its magnitude response using IIR filters. Load the FIR filter response data as a target (in the FIR Designer Target tab), then use the IIR tab to design an IIR filter set that closely matches the target magnitude response.

However, matching the magnitude response doesn’t necessarily reproduce the FIR filter’s phase response. FIRs can provide magnitude & phase processing that conventional minimum-phase IIR filters can’t replicate, including independent phase correction & linear-phase filtering (learn more about FIRs.)

Yes, FIR Designer can be used to to design EQ for any DSP device with user-accessible settings. While some brands don’t support user-loaded FIR filters, you can still design & enter IIR-filter-based EQ in most professional audio DSP devices.

Check the manufacturer’s documentation for instructions on entering EQ data into their control software. If the brand has a dedicated IIR emulation mode in FIR Designer, you can also find control software links on the Brand EQ Mode Lookup page.

Yes. Eclipse Audio DSP design software can export FIR filters, IIR filters and additional EQ data. Filters can be exported separately or combined as part of a complete loudspeaker preset. Data can be saved in a variety of formats for loading into any processor with user-accessible settings.

Check the supported file format for the processor’s control software, as well as the required sample rate, maximum filter length, and any requirements for coefficient format or file structure. This way you can be sure that the filter you design & export from FIR Designer will match the processor’s requirements.

Possibly. We’ve included all the FIR-capable brands we’re currently aware of, but pro audio manufacturers continue to introduce new DSP devices that may not yet be included. If you know of one we’ve missed, please let us know so we can keep this page up to date.
