Public Domain Audiobooks with Premium Sound. Voxelle is a home for thousands of free, public domain audiobooks: the classics, philosophy, poetry, history, and children's literature that incredible volunteers have recorded and given to everyone for free. We take that free library and make it a JOY to listen to. No ads. No subscriptions. No accounts. WHY VOXELLE Cleaner sound. We LOVE Librivox and the work of the Internet Archive and we give those volunteer readers the treatment they deserve. No background noise. Richer sound. No microphone noises. Consistent volume - even when different readers are involved. We even removed the intros to allow you to get to the stories quicker. You pay a small fee for the improved audio version and own it forever. No DRM so you can listen to it anywhere. The original versions and everything else in the app is totally free. A curated library, not a search box with a high focus on exposing the richness of the Western Canon: the Harvard Classics, a great books of the western world collection, kids and family shelves, and long listens for a road trip. Monthly themes and guided listens by topic. A player built for long books. Adjustable speed, a smart sleep timer that fades out at the end of a chapter, bookmarks, per book speed memory, and full offline downloads so you can listen anywhere. Browse by narrator. Find a reader you love and hear everything they have recorded. FOR THE PEOPLE WHO ACTUALLY LISTEN Homeschool families building a reading list. Self learners working through the canon. Anyone who wants the classics without a monthly bill or a wall of ads. Voxelle is for you. Every title in the free library stays free to stream and download. Enhanced, studio mastered editions of select books are available as one time purchases, never a subscription.
