Ardour 5.6

Ardour is an audio processing and editing application. It integrates broad hardware support, JACK and ALSA backends, flexible recording features, multi-channel nesting, import and exporting various file formats, comes with ready to use samples from freesound.org. It has a pretty editing UI, mixing, routing, monitoring, panning. Ardour allows non-destructive and non-linear editing, can be used for augmenting audio layers in video files even. And comes with many effect, input and output plugins. It's open source, but asks for donations on the download page for prebuilt binaries.
