Ardour is a hard disk recorder (HDR) and digital audio workstation (DAW). It is capable of simultaneously recording 24 or more channels of 32-bit audio at 48kHz.

Ardour is intended to function as a "professional" HDR system, replacing dedicated hardware solutions like the Mackie HDR and the Tascam 2424 and more traditional tape systems like the Alesis ADAT series. It supports MIDI Machine Control, so can be controlled from any MMC controller, such as the Mackie Digital 8 Bus mixer and many other modern digital mixers.

Suil is a lightweight C library for loading and wrapping LV2 plugin UIs.

Suil makes it possible to load a UI of any toolkit in a host using any other toolkit (assuming the toolkits are both supported by Suil). Hosts do not need to build against or link to foreign toolkit libraries to use UIs written with that toolkit (Suil performs its magic at runtime using dynamically loaded modules). The API is designed such that hosts do not need to explicitly support particular toolkits whatsoever.

If Suil supports a particular toolkit, then all hosts that use Suil will support that toolkit.
