Ardour vs Harrison Mixbus

Ardour is cross-platform and works on Windows & macOS.

Ardour is open source, so it can be downloaded and modified without restriction.

Unlike some other DAW's which often limit saving, exporting, or advanced features, Ardour permits you to try all the features for free, with the only limitation being ten minutes of project length maximum.
