This repo currently support Text-to-Audio Generation (including Music)
- Add the text-to-speech checkpoint
- Add the text-to-audio checkpoint that does not use FLAN-T5 Cross Attention
- Open-source the AudioLDM 1 & 2 training code.
- Support the generation of longer audio (> 10s)
- Optimizing the inference speed of the model.
- Integration with the Diffusers library
- Prepare running environment
conda create -n audioldm python=3.8; conda activate audioldm
pip3 install git+https://github.com/haoheliu/AudioLDM2.git
git clone https://github.com/haoheliu/AudioLDM2; cd AudioLDM2
- Start the web application (powered by Gradio)
python3 app.py
- A link will be printed out. Click the link to open the browser and play.
Prepare running environment
# Optional
conda create -n audioldm python=3.8; conda activate audioldm
# Install AudioLDM
pip3 install git+https://github.com/haoheliu/AudioLDM2.git
- Generate based on a text prompt
audioldm2 -t "Musical constellations twinkling in the night sky, forming a cosmic melody."
- Generate based on a list of text
audioldm2 -tl batch.lst
Sometimes model may not perform well (sounds wired or low quality) when changing into a different hardware. In this case, please adjust the random seed and find the optimal one for your hardware.
audioldm2 --seed 1234 -t "Musical constellations twinkling in the night sky, forming a cosmic melody."
You can choose model checkpoint by setting up "model_name":
audioldm2 --model_name "audioldm2-full-large-650k" -t "Musical constellations twinkling in the night sky, forming a cosmic melody."
We have three checkpoints you can choose for now:
- audioldm2-full (default): This checkpoint can perform both sound effect and music generation.
- audioldm2-music-665k: This checkpoint is specialized on music generation.
- audioldm2-full-large-650k: This checkpoint is the larger version of audioldm2-full.
usage: audioldm2 [-h] [-t TEXT] [-tl TEXT_LIST] [-s SAVE_PATH] [--model_name {audioldm2-full,audioldm2-music-665k,audioldm2-full-large-650k}] [-b BATCHSIZE] [--ddim_steps DDIM_STEPS] [-gs GUIDANCE_SCALE]
[-n N_CANDIDATE_GEN_PER_TEXT] [--seed SEED]
optional arguments:
-h, --help show this help message and exit
-t TEXT, --text TEXT Text prompt to the model for audio generation
-tl TEXT_LIST, --text_list TEXT_LIST
A file that contains text prompt to the model for audio generation
-s SAVE_PATH, --save_path SAVE_PATH
The path to save model output
--model_name {audioldm2-full,audioldm2-music-665k,audioldm2-full-large-650k}
The checkpoint you gonna use
-b BATCHSIZE, --batchsize BATCHSIZE
Generate how many samples at the same time
--ddim_steps DDIM_STEPS
The sampling step for DDIM
-gs GUIDANCE_SCALE, --guidance_scale GUIDANCE_SCALE
Guidance scale (Large => better quality and relavancy to text; Small => better diversity)
-n N_CANDIDATE_GEN_PER_TEXT, --n_candidate_gen_per_text N_CANDIDATE_GEN_PER_TEXT
Automatic quality control. This number control the number of candidates (e.g., generate three audios and choose the best to show you). A Larger value usually lead to better quality with
heavier computation
--seed SEED Change this value (any integer number) will lead to a different generation result.
