I have compiled neural-amp-modeler-lv2 using quite a few optimizations and have managed to get the CPU usage down a lot. On my Libre La Frite SoC/SBC (512MB RAM) which I believe is quite similar in speed to a RPi3 I can now use a WaveNet Standard model where I with my earlier optimized builds only managed to use a feather models. The feather model used to take up ~90% CPU but with this new build it only uses 48%. Standard models use 89-90%.
I have built the plugin under Debian 12/Bookworm arm64/aarch64 so I believe it should work on latest Modep but I would like to hear your feedback.
