Jukebox is an autoregressive model for music generation published by OpenAI in 2020. It is based on a hierarchical VQ-VAE and Scalable Transformers (based on Sparse Transformers ) to create long music samples that can be conditioned on Genres, Artists, Timing and Lyrics.
3 sampling strategies will be made available :
Ancestral sampling : tokens are generated in an autoregressive fashion and are then upsampled
Windowed sampling : in order to generate long sequences, samples are repeatedly produced from overlapping windows using the previous codes as context.
Primed sampling : a continuation of a previous audio is obtained using the VQ-VAE encoding of the audio as initial tokens for the ancestral sampling
The generated tokens are then passed through the VQ-VAE decoder to obtain the final audio.
The Lyric conditional informations are obtained using a Lyric Transformer model.
