Abstract

Multimodal generative models have shown impressive advances with the help of powerful diffusion models. Despite the progress, generating sound solely from text poses challenges in ensuring comprehensive scene depiction and temporal alignment. Meanwhile, video-to-sound generation limits the flexibility to prioritize sound synthesis for specific objects within the scene. To tackle these challenges, we propose a novel video-and-text-to-sound generation method, called ReWaS, where video serves as a conditional control for a text-to-audio generation model. Our method estimates the structural information of audio (namely, energy) from the video while receiving key content cues from a user prompt. We employ a well-performing text-to-sound model to consolidate the video control, which is much more efficient for training multimodal diffusion models with massive triplet-paired (audio-video-text) data. In addition, by separating the generative components of audio, it becomes a more flexible system that allows users to freely adjust the energy, surrounding environment, and primary sound source according to their preferences. Experimental results demonstrate that our method shows superiority in terms of quality, controllability, and training efficiency.

ReWaS

Prepare Python running environment

git clone https://github.com/naver-ai/rewas.git
# Install running environment
sudo apt-get update
sudo apt-get install -y python3-tk
sudo apt-get install -y ffmpeg
pip install -r requirements.txt

If the code raises the following error, 'No module named 'pytorch_lightning.utilities.rank_zero', please upgrade pytorch-lightning.

Download checkpoints

1. Download checkpoints from link that contains parameteres of ReWaS(AudioLDM-M) and phi.

2. Download the checkpoints of pretrained Synchformer, VAE, CLAP, 16kHz HiFiGAN, and 48kHz HiFiGAN from Synchformer and AudioLDM-training.

Test ReWaS

Please insert the video path and text prompt that you want to generate audio into 'test_samples.json'.

Use the following syntax:

python test.py \
  -ckpt ckpts/rewas.ckpt \
  --config configs/audioldm_m_rewas.yaml \
  --control_type energy_video \
  --save_path outputs \
  --testlist 'test_samples.json'

Evaluate model

We recommend the following evaluation metrics.

1. Energy MAE: ./eval_MAE.py
2. Melception Audio Quality
3. CLAP score

• Download CLAP weights from Hugging Face into evaluation/clap/CLAP_weights_2022.pth

  cd evaluation;
  python clap_score.py

• requirements: transformer>=4.28.1

4. Onset Accuracy
5. AV-align

   cd evaluation;
   python av_align_score.py --input_video_dir='/path/to/vggsound_video' --input_wav_dir='results/' --cache_path='./video_cache.json'

Customizing

If you want to build a new ReWaS or apply in other text-to-audio model, you can use tool_add_adapter.py
