Description
AudioLM represents a novel framework for generating high-quality audio with remarkable long-term consistency. At its core, AudioLM transforms the complex task of audio generation into a language modeling problem. It achieves this by mapping input audio into a sequence of discrete tokens, effectively treating audio as a form of language.

The model leverages a hybrid tokenization scheme to balance reconstruction quality with long-term structural coherence. It utilizes the discretized activations of a masked language model pre-trained on audio to capture long-term dependencies, while employing discrete codes from a neural audio codec for high-fidelity synthesis. This dual approach allows AudioLM to learn from large corpora of raw audio waveforms.
When trained on speech data, AudioLM can generate syntactically and semantically plausible speech continuations. Crucially, it maintains speaker identity, prosody, accent, and recording conditions of the initial prompt, even for speakers not encountered during training. This capability extends beyond speech, as demonstrated by its ability to generate coherent piano music continuations without relying on symbolic music representations.
AudioLM's architecture allows for various generation modes. Speech continuation involves providing a short audio prompt and receiving a natural, coherent extension. Acoustic generation focuses on sampling acoustic tokens to produce diverse audio samples with identical semantic content but varying speaker identities and recording conditions. Unconditional generation produces entirely novel audio sequences without any prompt, showcasing the model's generative breadth. The framework also highlights the importance of semantic tokens for linguistic coherence, demonstrating that acoustic tokens alone lead to less consistent content.
The model's versatility is further evidenced by its application to music generation, specifically piano continuations. By training on raw piano audio, AudioLM learns to produce musically coherent sequences, outperforming models trained solely on acoustic tokens. This indicates a robust understanding of audio structure and content, applicable across different domains.
