How to prepare dataset for RIR & Musan Augmentation

[csetanmayjain]

Hi, Would like know how to prepare dataset for RIR & Musan Augmentation I go through the script, and understand that it needs data in .mdb format that should be inside lmdb folder. I have raw audio files, how to prepare data for it? Also, would like to know, is there any flag in the configuration file, which I can use as a flag to apply augmentation or not.

Thanks

Just need preparing a wav.scp file and specify the path to save lmdb file. Then run "python make_lmdb.py /path/to/wav.scp /path/to/lmdb_dir" to prepare the lmdb file. You can turn off augmentation by setting the corresponding probability to 0, or simply do not pass the corresponding lmdb file in run.sh
