BS-RoFormer (Band-Split RoPE Transformer)

BS-RoFormer (Band-Split RoPE Transformer) is a music source separation architecture introduced in a 2023 research paper. It divides an audio spectrogram into frequency bands and uses a transformer to model their relationships. Open-source implementations and community-trained variants are available, and some publicly shared weights have used MUSDB18-HQ in training. Because BS-RoFormer is an architecture rather than one fixed model, commercial-use considerations depend on the specific implementation, weights, training data, and license. A related architecture is Mel-Band RoFormer.
