OpenAI Jukebox vs. AudioLM

We are thrilled to introduce Jukebox, an innovative neural network engineered to generate music across a wide variety of genres and styles, complete with basic vocalizations, all rendered as raw audio. In conjunction with the release of the model weights and accompanying code, we are providing a user-friendly tool that allows individuals to delve into the music samples produced by Jukebox. By entering specific parameters such as genre, artist, and lyrics, users can receive entirely original compositions created from scratch. Jukebox is adept at producing a diverse range of musical and vocal forms and can creatively interpret lyrics that were not included in its training dataset. The lyrics featured here have been collaboratively developed by OpenAI researchers and a language model. When given lyrics from its training set, Jukebox generates songs that significantly differ from the originals, demonstrating its impressive creative abilities. Users have the option to input a 12-second audio snippet for Jukebox to expand upon, resulting in an output that embodies a chosen artistic style. Our commitment to music innovation is driven by a desire to push the boundaries of generative models even further. By employing a quantization-based methodology known as VQ-VAE, Jukebox's autoencoder efficiently compresses audio into a discrete latent space, paving the way for groundbreaking sound generation. As we move forward with refining these technologies, we eagerly anticipate the myriad of creative avenues that await exploration. The future of music generation looks promising, and we are excited to be part of this transformative journey.

AudioLM represents a groundbreaking advancement in audio language modeling, focusing on the generation of high-fidelity, coherent speech and piano music without relying on text or symbolic representations. It arranges audio data hierarchically using two unique types of discrete tokens: semantic tokens, produced by a self-supervised model that captures phonetic and melodic elements alongside broader contextual information, and acoustic tokens, sourced from a neural codec that preserves speaker traits and detailed waveform characteristics. The architecture of this model features a sequence of three Transformer stages, starting with the semantic token prediction to form the structural foundation, proceeding to the generation of coarse tokens, and finishing with the fine acoustic tokens that facilitate intricate audio synthesis. As a result, AudioLM can effectively create seamless audio continuations from merely a few seconds of input, maintaining the integrity of voice identity and prosody in speech as well as the melody, harmony, and rhythm in musical compositions. Notably, human evaluations have shown that the audio outputs are often indistinguishable from genuine recordings, highlighting the remarkable authenticity and dependability of this technology. This innovation in audio generation not only showcases enhanced capabilities but also opens up a myriad of possibilities for future uses in various sectors like entertainment, telecommunications, and beyond, where the necessity for realistic sound reproduction continues to grow. The implications of such advancements could significantly reshape how we interact with and experience audio content in our daily lives.
