Set fft_size per Device?

[thowe-switzerland]

Hello all

If I see it correctly, the fft_size is currently a global option which applies to all devices. But now I have the challenge that I would like to combine several devices with different bandwidths: 3MHz and 6MHz. But I would also like to double the fft_size for the 6MHz so that the channel width is about the same.

Is there a reason that the fft_size is a global option and cannot be set per device?

Best thanks & greetings
Thomas

fit_size is used as a global in the code so it would take a good amount of refactoring to make it per-device. With that said, I don't there is anything preventing it if you want to try. You can always run two instances of rtl_airband in the meantime.

Thank you. If nothing speaks against it I will look at the appropriate opportunity whether I can adapt that.

Two separate instances don't work here, because channels from both devices should flow into one mixer.
