Model overview

audiogen-medium is a text-to-audio model developed by the Facebook AI Research (FAIR) team. It is an autoregressive transformer language model that can generate general audio content conditioned on text prompts. Unlike existing speech synthesis models, audiogen-medium operates over discrete audio representations learned from raw waveforms using an EnCodec tokenizer. This allows the model to generate more diverse and flexible audio outputs compared to traditional text-to-speech systems. audiogen-medium is a variant of the original AudioGen model that follows the MusicGen architecture, using a 16kHz EnCodec tokenizer with a delay pattern between the codebooks to enable faster generation.

Model inputs and outputs

Inputs

  • Text prompts: The model takes in text descriptions as input, which are used to condition the audio generation.

Outputs

  • Audio waveforms: The model outputs general audio content in the form of raw waveforms, which can represent a variety of sounds beyond just speech.

Capabilities

audiogen-medium can generate diverse audio samples ranging from environmental sounds like dog barks or emergency vehicle sirens, to more abstract soundscapes. The model is able to capture timbres, textures and dynamics in the generated audio that go beyond what traditional text-to-speech models can achieve. However, the model is not capable of generating realistic vocals or speech.

What can I use it for?

The primary intended use of audiogen-medium is for research on AI-based audio generation, including efforts to better understand the capabilities and limitations of generative models. The model could also be used by machine learning enthusiasts and hobbyists to explore the potential of text-to-audio synthesis. However, the model should not be used for downstream applications without further evaluation and mitigation of potential biases and risks.

Things to try

One interesting aspect of audiogen-medium is its ability to generate audio content that is responsive to the provided text prompts, while still exhibiting a degree of creative diversity. Experimenting with different types of text descriptions, from concrete to abstract, can yield a wide range of audio outputs that capture different moods, textures and soundscapes. Additionally, comparing the performance of audiogen-medium to that of similar models like MusicGen could provide insights into the strengths and limitations of each approach to text-conditional audio generation.

Model inputs and outputs musicgen-medium is a text-to-music model that takes in text descriptions as input and generates corresponding audio samples as output. The model is built on an autoregressive Transformer architecture and a 32kHz EnCodec tokenizer with 4 codebooks. Inputs Text prompt**: A text description that conditions the generated music, such as "lo-fi music with a soothing melody". Outputs Audio sample**: A generated 32kHz stereo audio waveform representing the music based on the text prompt. Capabilities musicgen-medium is capable of generating high-quality music across a variety of styles and genres based on text prompts. The model can produce samples with coherent melodies, harmonies, and rhythmic structures that match the provided descriptions. For example, it can generate "lo-fi music with a soothing melody", "happy rock", or "energetic EDM" when given the corresponding text inputs. What can I use it for? musicgen-medium is primarily intended for research on AI-based music generation, such as probing the model's limitations and understanding how to further improve the state of the art. It can also be used by machine learning enthusiasts to generate music guided by text or melody and gain insights into the current capabilities of generative AI models.
