[QUOTE="Michael John, post: 202177, member: 830"] Hi Everyone, Mark raised some great questions with me via email which has resulted in today's release - Version 1.6. [URL]https://eclipseaudio.com.au/fir-designer/release-notes/[/URL] It's now possible to export filters from Direct Design mode to a new FIR Designer Target file format, which can then be imported as the target file in the regular workflow. This is useful for experimentation without a license key. In the Target tab, Target Design and Target File responses can now be used together. On the Target tab, selecting Design + File will combine the magnitude spectrums of both. This is useful for specifying crossovers in a Target File and using the Target Design to set the overall system response curve. Also, there's now an IIR filters tab. Shock horror!! If you need to use regular IIR high-pass or low-pass filters inline with a FIR filter, those IIR filters can be entered. They are applied to the speaker measurement, and the FIR filter can then be designed with knowledge of what the IIR filters are doing, especially to the loudspeaker phase. These IIR's can be useful for things like subwoofer HP filters or just DC blocking filters. Regards, Michael [/QUOTE]
