Hybrid-Net

Real-time audio source separation, generate lyrics, chords, beat.

A transformer-based hybrid multimodal model, various transformer models address different problems in the field of music information retrieval, these models generate corresponding information dependencies that mutually influence each other.

An AI-powered multimodal project focused on music, generate chords, beats, lyrics, melody, and tabs for any song.

U-Net network model for audio source separation, Pitch-Net, Beat-Net, Chord-Net and Segment-Net based on the transformer model. Apart from establishing the correlation between the frequency and time, the most important aspect is to establish the mutual influence between different networks.

The entire AI-powered process is implemented in aitabs.py, while the various network structure models can be referenced in the models folder.

Note: U-Net and Segment-Net use the stft spectrum of audio as input. Beat-Net uses three spectrograms of drums, bass, and other instruments as input,Chord-Net uses one spectrogram of the background music.
