Right, just fixed that, too. Thanks for pointing it out.

The FIR engine was successfully compiled into the executable file FIR_engine.exe


Perfect.
And to think that I do everything with copy and paste in order not to be wrong!
I am happy to have had two saviors on your level.
Now that I have compiled my Ferrari, I greet you and thank you.
See you when I learn to drive.
Ciao.
Grazie mille!

Drive carefully.

Just in case people don't know... you can use ecasound+LADSPA in combination with Pulse Audio. This You can implement both IIR and FIR filters via that route.

ALSA has a Pulse device, which IIRC appears as a virtual "monitor" device in Pulse and gets all the sounds the system sends to Pulse Audio. So, in Pulse you disable the output device you wish to use. Then you tell ecasound to use the ALSA pulse device as the input, and send the output to the soundcard you deactivated under Pulse. You can still use the Pulse audio volume control, which is very convenient, and everything works just the same as if playback was coming via Pulse except you get crossover functionality via ecasound. I use this approach on one of the systems in my home.

If someone would like, I can provide a more detailed example.
