    >> Hello,

    Our software doesn’t currently support direct FIR conversion, however you can load a filter (to be copied) into the Target tab then use the subsequent FIR tabs to match the target. Depending on the original filter, this should get you very close (and maybe even an exact match) and the resulting filter can be exported in any/many formats for other platforms.

    You can use the demo versions to try the workflow but, without a license, you won’t be able to export.

    Best regards,
