Model overview

audio-ldm is a text-to-audio generation model created by Haohe Liu, a researcher at CVSSP. It uses latent diffusion models to generate audio based on text prompts. The model is similar to stable-diffusion, a widely-used latent text-to-image diffusion model, but applied to the audio domain. It is also related to models like riffusion, which generates music from text, and whisperx, which transcribes audio. However, audio-ldm is focused specifically on generating a wide range of audio content from text.

Model inputs and outputs

The audio-ldm model takes in a text prompt as input and generates an audio clip as output. The text prompt can describe the desired sound, such as "a hammer hitting a wooden surface" or "children singing". The model then produces an audio clip that matches the text prompt.


  • Text: A text prompt describing the desired audio to generate.
  • Duration: The duration of the generated audio clip in seconds. Higher durations may lead to out-of-memory errors.
  • Random Seed: An optional random seed to control the randomness of the generation.
  • N Candidates: The number of candidate audio clips to generate, with the best one selected.
  • Guidance Scale: A parameter that controls the balance between audio quality and diversity. Higher values lead to better quality but less diversity.


  • Audio Clip: The generated audio clip that matches the input text prompt.


audio-ldm is capable of generating a wide variety of audio content from text prompts, including speech, sound effects, music, and beyond. It can also perform audio-to-audio generation, where it generates a new audio clip that has similar sound events to a provided input audio. Additionally, the model supports text-guided audio-to-audio style transfer, where it can transfer the sound of an input audio clip to match a text description.

What can I use it for?

audio-ldm could be useful for various applications, such as:

  • Creative content generation: Generating audio content for use in videos, games, or other multimedia projects.
  • Audio post-production: Automating the creation of sound effects or music to complement visual content.
  • Accessibility: Generating audio descriptions for visually impaired users.
  • Education and research: Exploring the capabilities of text-to-audio generation models.

Things to try

When using audio-ldm, try providing more detailed and descriptive text prompts to get better quality results. Experiment with different random seeds to see how they affect the generation. You can also try combining audio-ldm with other audio tools and techniques, such as audio editing or signal processing, to create even more interesting and compelling audio content.

Tango is a latent diffusion model (LDM) for text-to-audio (TTA) generation, capable of generating realistic audios including human sounds, animal sounds, natural and artificial sounds, and sound effects from textual prompts. It uses the frozen instruction-tuned language model Flan-T5 as the text encoder and trains a UNet-based diffusion model for audio generation. Compared to current state-of-the-art TTA models, Tango performs comparably across both objective and subjective metrics, despite training on a dataset 63 times smaller. The maintainer has released the model, training, and inference code for the research community. Tango 2 is a follow-up to Tango, built upon the same foundation but with additional alignment training using Direct Preference Optimization (DPO) on the Audio-alpaca dataset, a pairwise text-to-audio preference dataset. This helps Tango 2 generate higher-quality and more aligned audio outputs. Model inputs and outputs Inputs Prompt**: A textual description of the desired audio to be generated. Steps**: The number of steps to use for the diffusion-based audio generation process, with more steps typically producing higher-quality results at the cost of longer inference time.

Outputs Audio**: The generated audio clip corresponding to the input prompt, in WAV format. Capabilities Tango and Tango 2 can generate a wide variety of realistic audio clips, including human sounds, animal sounds, natural and artificial sounds, and sound effects. For example, they can generate sounds of an audience cheering and clapping, rolling thunder with lightning strikes, or a car engine revving. What can I use it for? The Tango and Tango 2 models can be used for a variety of applications, such as: Audio content creation**: Generating audio clips for videos, games, podcasts, and other multimedia projects. Sound design**: Creating custom sound effects for various applications. Music composition**: Generating musical elements or accompaniment for songwriting and composition.
