Change Log

• 2024-12-16: Add Important things to know to make AudioSR work.
• 2023-09-24: Add replicate demo (@nateraw); Fix error on windows, librosa warning etc (@ORI-Muchim).
• 2023-09-16: Fix DC shift issue. Fix duration padding bug. Update default DDIM steps to 50.

Gradio Demo

To run the Gradio demo locally:

1. Install dependencies: pip install -r requirements.txt
2. Run the app: python app.py
3. Open the URL displayed to view the demo

Commandline Usage

Installation

# Optional
conda create -n audiosr python=3.9; conda activate audiosr
# Install AudioLDM
pip3 install audiosr==0.0.7
# or
# pip3 install git+https://github.com/haoheliu/versatile_audio_super_resolution.git

Usage

Process a list of files. The result will be saved at ./output by default.

audiosr -il batch.lst

Process a single audio file.

audiosr -i example/music.wav

Full usage instruction

> audiosr -h

> usage: audiosr [-h] -i INPUT_AUDIO_FILE [-il INPUT_FILE_LIST] [-s SAVE_PATH] [--model_name {basic,speech}] [-d DEVICE] [--ddim_steps DDIM_STEPS] [-gs GUIDANCE_SCALE] [--seed SEED]

optional arguments:
  -h, --help            show this help message and exit
  -i INPUT_AUDIO_FILE, --input_audio_file INPUT_AUDIO_FILE
                        Input audio file for audio super resolution
  -il INPUT_FILE_LIST, --input_file_list INPUT_FILE_LIST
                        A file that contains all audio files that need to perform audio super resolution
  -s SAVE_PATH, --save_path SAVE_PATH
                        The path to save model output
  --model_name {basic,speech}
                        The checkpoint you gonna use
  -d DEVICE, --device DEVICE
                        The device for computation. If not specified, the script will automatically choose the device based on your environment.
  --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)
  --seed SEED           Change this value (any integer number) will lead to a different generation result.
  --suffix SUFFIX       Suffix for the output file

TODO

• Add gradio demo.
• Optimize the inference speed.
