Try figuring out features which causes NaN loss

I'm trying to train the speech recognition model through our company's database. When I used Librispeech DB, there was no problem with model training. On the other hand, when using our company's DB, it causes NaN loss when training first epoch. As a result of searching, I found that certain wave files had problems like low quality, small volume, unmatched wave and text, and so on. Is there any way that I can check if wave file causes NaN loss when putting to model?
