MVSEP-CDX23-Cinematic-Sound-Demixing

Model for Sound demixing challenge 2023: Cinematic Sound Demixing Track - CDX'23. Model performs separation of music into 3 stems "dialog (speech)", "effect (sfx)", "music". Model was trained on DnR dataset. It based on Demucs4. Test set in CDX23 contest was very different from DnR train data. So we released best models with best metrics for DnR test set.

Usage

    python inference.py --input_audio mixture1.wav mixture2.wav --output_folder ./results/

With this command audios with names "mixture1.wav" and "mixture2.wav" will be processed and results will be stored in ./results/ folder in WAV format.

• Note: for slightly better quality of results use --high_quality parameter. It will be ~3 times slower.

Quality metrics

Quality were measured on DnR test set

• Note 1: SDR - signal to distortion ratio. Larger is better.
• Note 2: Music stem in DnR dataset can contain vocals
