Extract the samples of ddb/ddi soundbanks.

Requirements

pip install pyyaml

Examples

python ./extract_wav.py --src_path ./XXX.ddb
python ./extract_ddi.py --src_path ./XXX.ddi
python ./rename_wav.py --work_dir ./XXX

FRM2 files are not necessary for the wav workflow, so only run the following command if you have special desire for the extracted frm2 files:

python ./extract_frm2.py --src_path ./XXX.ddb

Guide for Python Beginners

1. Download and install miniconda
   At the end installation, remember to set conda init as yes (or run it manually).
2. Create a python 3.10 environment by running conda create -n py310 python=3.10
3. Activate your new environment: conda activate py310
4. Install the required dependencies: pip install pyyaml
5. Run the scripts following the previous example!

Usage:

usage: extract_ddi.py [-h] --src_path SRC_PATH

optional arguments:
  -h, --help           show this help message and exit
  --src_path SRC_PATH  source ddi file path
  --save_temp          save temp files
  --cat_only           only concat ddi.yml, assuming temp files exist.

usage: extract_wav.py [-h] --src_path SRC_PATH [--dst_path DST_PATH] [--merge] [--silence_interval SILENCE_INTERVAL]

optional arguments:
  -h, --help            show this help message and exit
  --src_path SRC_PATH   source ddb file path
  --dst_path DST_PATH   destination extract path, default to be "./[name]/wav.zip (merge.wav)"
  --merge               enable to generate a merged large wav file
  --silence_interval SILENCE_INTERVAL
                        silence interval seconds when "merge" is enabled, default to be 0

usage: extract_frm2.py [-h] --src_path SRC_PATH [--dst_path DST_PATH]
