AudioToken: Adaptation of Text-Conditioned Diffusion Models for Audio-to-Image Generation

This repo contains the official PyTorch implementation of AudioToken: Adaptation of Text-Conditioned Diffusion Models for Audio-to-Image Generation

Abstract

In recent years, image generation has shown a great leap in performance, where diffusion models play a central role. Although generating high-quality images, such models are mainly conditioned on textual descriptions. This begs the question: how can we adopt such models to be conditioned on other modalities?. In this paper, we propose a novel method utilizing latent diffusion models, trained for text-to-image-generation, to generate images, conditioned on audio recordings. Using a pre- trained audio encoding model, the proposed method encodes audio into a new token which can be considered as an adap- tation layer between the audio and text representations. Such a modeling paradigm requires a small number of trainable param eters making the proposed approach appealing for lightweight optimization. Results suggest the proposed method is superior to the evaluated baseline methods considering both objective and subjective metrics.

Pre-Trained Embedder

alt text

The embedder's weights, which we pre-trained and on which the article is based, may be found at: output/embedder_learned_embeds.bin

Training

First, download our data set. VGGSound. Download links for the dataset can be found here.

export MODEL_NAME="CompVis/stable-diffusion-v1-4"
export DATA_DIR="./vggsound/"
export OUTPUT_DIR="output/"

accelerate launch train.py \
  --pretrained_model_name_or_path=$MODEL_NAME \
  --data_dir=$DATA_DIR \
  --output_dir=$OUTPUT_DIR 
  --resolution=512 \
  --train_batch_size=4 \
  --gradient_accumulation_steps=4 \
  --max_train_steps=30000 \
  --learning_rate=1.0e-05 \

Note: Change the resolution to 768 if you are using the stable-diffusion-2 768x768 model.

Inference

After you've trained a model with the above command, you can simply generate images using the following script:

export MODEL_NAME="CompVis/stable-diffusion-v1-4"
export DATA_DIR="./vggsound/"
export OUTPUT_DIR="output/"
export LEARNED_EMBEDS="output/embedder_learned_embeds.bin"

accelerate launch inference.py \
  --pretrained_model_name_or_path=$MODEL_NAME \
  --data_dir=$DATA_DIR \
  --output_dir=$OUTPUT_DIR \ 
  --learned_embeds=$LEARNED_EMBEDS
