open, challenging dataset for audio classification


Do you know of an open audio dataset that could be used for audio classification? I am a part of a group of students doing the deep learning course right now. I wanted us to exchange best practices on working with audio (and research new methods as they apply to working with animal audio) but the dataset I went for unfortunately proved too easy for deep learning models (the first submission from a student brought the error on the validation set to 0.2%). You can find the repository we are collectively working on here.

If a dataset like that would come to your mind and you would be so kind and share the details with me, that would be greatly appreciated!

Thank you!
