1. We have a new example: [Music Player](https://github.com/castle-engine/castle-engine/tree/master/examples/audio/music_collection_player), a simple application that allows to play a chosen audio track with UI similar to typical mobile music/audiobook players.
This example has a nice backstory: For _Mother’s Day_ (which is 26th May in Poland) my daughter and I made a gift for The Wife: a private application (Android apk) with a few audio tracks just for her. There’s an audio track with my daughter signing, with our cat meowing and other gems:)
Don’t worry, the version I committed as our _Castle Game Engine_ demo has more mainstream sounds :), using open-source audio tracks from [OpenGameArt.org](http://OpenGameArt.org). Big thanks go to [The Cynic Project](https://cynicmusic.com/) (see also [Pixelsphere](https://pixelsphere.org/) project) for the cool public domain music tracks! See the [credits](https://github.com/castle-engine/castle-engine/blob/master/examples/audio/music_collection_player/data/songs/AUTHORS.md) for details about audio and art authors.
Have fun extending this into your own ideas and I hope this inspires you to have fun with our engine:)
Try out the example [playing on the web](https://castle-engine.io/web-demos/examples/audio/music_collection_player/) right now! Though it looks best in _portrait_ aspect, like on mobile.
In a bit related news, please [sign and spread the word about the need to keep Android open](https://keepandroidopen.org/). Sadly, Google plans to practically break this important aspect of Android, which will prohibit making such fun experiments like “family Android app” and endanger more important use-cases (like distributing VPN apps in countries with totalitarian regimes).
2. We have a few important audio fixes in the engine (thanks to experience with above example, but also a review done by Claude — more on this in a future news post):
3. We have fixed loading _float_ textures on OpenGLES (Android, iOS). This makes our [optimized skinned animation](https://castle-engine.io/skin) work in an optimal way on your phones.
4. We made important glTF skinned animation fix (affecting all platforms): multiple skins that affect the same skeleton are now supported (if equivalent) or at least cleanly tolerated (we make a clear warning, and render part of the model as static).
As always, we hope you have fun developing games and we appreciate [your support on Patreon](https://www.patreon.com/c/castleengine). Thank you!
