ok, thank you for quick reply
We use usually rephase, but for a project we need chebyshev filter type 1 for crossover use, in minimum phase FIR format,, it is possible?
Yes, to create a Chebyshev equivalent FIR filter, use the ‘FIR: Magnitude Adjust’ tab in FIR Creator EX. You can try this in the demo mode. However, since you mentioned minimum-phase, it’s much more efficient to implement this using IIR biquads.
For export IIR coefficient we need FIR Designer or Creator is ok?
The FIR Creator EX ‘IIR Filters’ tab can be used to generate biquad coefficients, which can be exported from that tab.
Please download the demo version and experiment with all the tabs in the workflow.
To learn more about the workflow, see the first two ‘FIR Designer’ videos on:

About audio quality, are there differences in quality for the same filter between Fir Creator and Rephase?
Thank again
Best regards
No. The perceived ‘quality’ of FIR and IIR filter processing relates to the design choices in creating the filters, not the choice of program.
