$ python audioset_augmentor/download.py [--file_path='assets/balanced_train_segments.csv' --savedir='.data' --n_jobs=4 --delay=0.05]
  • Preprocess Audio
    • Process adjust volume, sample rate, file type on audio files.
$ python audioset_augmentor/preprocess.py [--master_dir, --out_dir, --meta_path='assets/balanced_train_segments.csv' --out_sr=22050 --min_size=1000000(file checker) --n_jobs=4]
