ASRock Industrial NUC BOX-255H Running Linux: OpenVINO AI Plugins for Audacity

Music Separation

This plugin lets you separate a music composition into separate tracks. Probably the most famous example of this type of technology being used is in the Beatles song Now and Then. The song was restored by isolating instruments, vocals, and individual conversations using audio restoration technology over a four-year period using a neural network. The neural network used for that song was extremely sophisticated.

In the image below, I’ve loaded a music track. Before selecting OpenVINO Music Separation (from the Effect menu), remember to select the whole track (CTRL+A_ or part of the track for the separation.

Next, choose the separation mode and the OpenVINO Inference Device. The CPU will use the Intel Core Ultra 7 255H, the GPU uses the Intel Graphics Arc 140T, and the NPU uses the Intel AI Boost.

In the example below, I’m going to use the GPU. The advanced options box lets you define the number of shifts.

It took 18 seconds for the Arc 140T iGPU to separate the music track into 4 separate stems. There’s now separate tracks for drums, bass, other instruments, and vocals. In the image below, I’ve muted all but the vocals.

If I repeat the process but this time using the CPU as the inference device, the separation takes 54 seconds to complete. The NUC-255H has a powerful CPU, but the GPU speedup is impressive.

Using the NPU took 58 seconds to process the track. I’m showing NPU usage using the Resources monitoring utility below.
