+```shell
+sudo snap install intel-npu-driver
+sudo snap connect audacity:npu-libs intel-npu-driver:npu-libs

 > The models (which are roughly 6.2 GiB in size total) are NOT built into the snap. To use the AI features you must download and install them from the command line. Note that downloading the models may take several minutes or longer, depending on the speed of your internet connection. Please be patient!
