Hello @luc! We are so happy to see you with us! Welcome to Elfsight Community
Unfortunately, at the moment, Audio Player widget doesn’t have this option, but we are planning to release it in the future.
We already have such a request in our Wishlist. Please vote for this feature in this category - Bulk uploaded of audio files with auto filename fill - #15 by Max and you’ll receive a notification upon its release.
If any questions come up, just let us know and we’ll be happy to help.
Have a nice day
