Hi,
Thank you for creating such a great platform for creative people around the world to share their creations, and find resources for them to reuse!
I am Olga Bulat from Openverse (formerly CC Search). We are currently working on adding search for CC-licensed audio on top of the existing image search. We hope to add audio player, too.
The API documentation says that preview audio files also require authentication. However, we found that they can be played even without authentication. This is an example I tried in Safari, not logged in:
https://freesound.org/data/previews/415/415362_6044691-hq.mp3 . Will the preview require authentication as stated in the API docs, or will it be possible to access them without it?
