Facts

What it does

AudioGen is a text-guided audio generation model that generates sounds from text.github.com · 3 Oct 2026

Intended users

The model card names audio, machine learning, and AI researchers, as well as amateurs learning about generative models, as primary users.github.com · 3 Oct 2026

Model architecture

The released model combines EnCodec audio tokenization with an autoregressive Transformer language model and has 1.5 billion parameters.github.com · 3 Oct 2026

Prompt generation

The documented API generates audio samples from text descriptions, with an example configured to generate five-second samples.github.com · 3 Oct 2026

Generation modes

The training documentation describes conditional and unconditional generation, audio continuation from a prompt, and greedy, temperature, top-K, and top-P sampling.github.com · 3 Oct 2026

Model availability

The AudioGen instructions list one pretrained model, facebook/audiogen-medium, and a local Jupyter notebook demo.github.com · 3 Oct 2026

Hardware requirement

The instructions say inference with the medium-sized models requires a GPU with at least 16 GB of memory.github.com · 3 Oct 2026

License

The repository says its code is MIT-licensed and its model weights use CC-BY-NC 4.0.github.com · 3 Oct 2026

Training data

The instructions say the datasets used to train AudioGen are not provided.github.com · 3 Oct 2026

Language limit

The model card says AudioGen was trained on English descriptions and performs less well in other languages.github.com · 3 Oct 2026

Output limit

The model card says AudioGen cannot generate realistic vocals and may require prompt engineering for satisfying results.github.com · 3 Oct 2026

Responsible use

The model card advises against downstream use without further risk evaluation and mitigation.github.com · 3 Oct 2026

Support

The model card directs questions and comments to the project’s GitHub repository or its issue tracker.github.com · 3 Oct 2026

Purpose

AudioGen is a text-to-sound generation model provided through AudioCraft.github.com · 3 Oct 2026

Model design

The provided reimplementation is a single-stage autoregressive Transformer trained over a 16 kHz EnCodec tokenizer with four codebooks sampled at 50 Hz.github.com · 3 Oct 2026

Model distinction

The provided models are not the original models used to report results in the AudioGen publication.github.com · 3 Oct 2026

Available model

The page lists one pretrained AudioGen model, facebook/audiogen-medium, with 1.5 billion parameters.github.com · 3 Oct 2026

Generation

The example API generates sound from text descriptions and shows saving output as WAV audio.github.com · 3 Oct 2026

Sampling controls

Generation supports greedy sampling, temperature sampling, top-K sampling, and top-P nucleus sampling.github.com · 3 Oct 2026

Audio continuation

The generation stage supports conditional or unconditional sample generation and audio continuation from a prompt.github.com · 3 Oct 2026

Installation

AudioCraft installation requires Python 3.9 and PyTorch 2.1.0; ffmpeg is also recommended by the repository instructions.github.com · 3 Oct 2026

Local demo

The maker provides a Jupyter notebook demo that can be run locally with a GPU.github.com · 3 Oct 2026

Training

AudioGenSolver implements the training pipeline, but the maker says it may not fully reproduce the paper results and does not provide the AudioGen training datasets.github.com · 3 Oct 2026
