OpenVINO™ AI Plugins for Audacity* :metal:

A set of AI-enabled effects, generators, and analyzers for Audacity®. These AI features run 100% locally on your PC :computer: -- no internet connection necessary! OpenVINO™ is used to run AI models on supported accelerators found on the user's system such as CPU, GPU, and NPU.

• Music Separation:musical_note: -- Separate a mono or stereo track into individual stems -- Drums, Bass, Vocals, & Other Instruments.
• Noise Suppression:broom: -- Removes background noise from an audio sample.
• Music Generation & Continuation:notes: -- Uses MusicGen LLM to generate snippets of music, or to generate a continuation of an existing snippet of music.
• Whisper Transcription:microphone: -- Uses whisper.cpp to generate a label track containing the transcription or translation for a given selection of spoken audio or vocals.
• Super Resolution:sparkles: -- Upscales and enriches audio for improved clarity and detail.

• Audacity® development team & Muse Group-- Thank you for your support!
• Audacity® GitHub -- https://github.com/audacity/audacity
• Whisper transcription & translation analyzer uses whisper.cpp (with OpenVINO™ backend): https://github.com/ggerganov/whisper.cpp
• Music Generation & Continuation use MusicGen model, from Meta.
  • We currently have support for MusicGen-Small, and MusicGen-Small-Stereo
  • The txt-to-music pipelines were ported from python to C++, referencing logic from the Hugging Face transformers project: https://github.com/huggingface/transformers
• Music Separation effect uses Meta's Demucs v4 model (https://github.com/facebookresearch/demucs), which has been ported to work with OpenVINO™
• Noise Suppression:
  • noise-suppression-denseunet-ll: from OpenVINO™'s Open Model Zoo: https://github.com/openvinotoolkit/open_model_zoo
  • DeepFilterNet2 & DeepFilterNet3:
    • Ported the models & pipeline from here: https://github.com/Rikorose/DeepFilterNet
    • We also made use of @grazder's fork / branch (https://github.com/grazder/DeepFilterNet/tree/torchDF-changes) to better understand the Rust implementation, and so we also based some of our C++ implementation on torch_df_offline.py found here.
