The editor has unlimited undo/redo capabilities and can save independent "versions" of a track or an entire piece

Ardour's editor supports the community-developed LADSPA plugin standard. Arbitrary chains of plugins can be attached to any portion of a track. Every mixer strip can have any number of inputs and outputs, not just mono, stereo or 5.1. An N-way panner is included, with support for various panning models. Pre- and post-fader sends exist, each with their own gain and pan controls. Every mixer strip acts as its own bus, and thus the bus count in Ardour is unlimited. You can submix any number of strips into another strip.

Ardour's channel capacity is limited only by the number on your audio interface and the ability of your disk subsystem to stream the data back and forth.

JACK (the JACK Audio Connection Kit) is used for all audio I/O, permitting data to be exchanged in perfect samplesync with other applications and/or hardware audio interfaces.

Ardour is sample rate and size neutral - any hardware formats from 8 to 32 bits, and rates from 8kHz to 192kHz. Internal processing in 32/64 bit IEEE floating point format.

Spleeter is the Deezer source separation library with pretrained models written in Python and uses Tensorflow. It makes it easy to train source separation model (assuming you have a dataset of isolated sources), and provides already trained state of the art model for performing various flavour of separation : Vocals (singing voice) / accompaniment separation (2 stems) Vocals / drums / bass / other separation (4 stems) * Vocals / drums / bass / piano / other separation (5 stems) 2 stems and 4 stems models have state of the art performances on the musdb dataset. Spleeter is also very fast as it can perform separation of audio files to 4 stems 100x faster than real-time when run on a GPU. We designed Spleeter so you can use it straight from command line as well as directly in your own development pipeline as a Python library.

A sound file is read by the software, and a 128-bit message is stored in a watermark in the output sound file. For human listeners, the files typically sound the same.

However, the 128-bit message can be retrieved from the output sound file. Our tests show, that even if the file is converted to mp3 or ogg (with bitrate 128 kbit/s or higher), the watermark usually can be retrieved without problems. The process of retrieving the message does not need the original audio file (blind decoding).
