Hey HN community! Creator of DagsHub here. Hacktoberfest 2021 is well underway, but there's still a lot of time left, and I was missing some opportunities to contribute to the community on the ML/DS fronts.We've decided to support Hacktoberfest by creating an open-source catalog of datasets in the audio domain. The idea is to have a bunch of audio datasets, which will be completely open-source, with the ability to view, visualize (waveform, spectrograms, etc), and download to use in your projects. Check out this dataset that I created as an example:  can read the full guidelines here: 
Would be happy to answer questions, but I think if you're passionate about open-source ML, this is a great opportunity to contribute.
