This is the repository for Loopy Audio Looper 2, which is available on the Play Store:

This app is meant to provide a simple solution for anyone who wants to loop audio files easily, like DJs, artists or musicians. It can be used for practice sessions, as a source of uninterrupted background atmospheres or to play endless beat loops.

If you have tried it before, you might know that it is really hard to find a player that just perfectly and reliably loops an audio track for you. It's a known problem of the Android OS. This player aims to give you just that: Seamless looping. Loopy 2 uses low-level code to make sure there are no hickups, which could still be observed in some situations with its predecessor.

The app plays audio files from your media library or files you select from your file browser. You can have a file repeat endlessly, or automatically skip to another loop when it reaches the end.

Important: If you find bugs in the app, use the contact function in the app so I can fix them faster. If you like the app but are missing a feature, feel free to let me know that too so I can consider it in future releases.

Please be aware, that Loopy 2 is not an audio editor! That means if you need exact results, your files need to be prepared and cut properly.

This is an Android project using Kotlin and C++. If you want to play around with it, or fork it, you should be able to just clone the repository and build the app in Android studio.

Internally, Loopy 2 uses oboe to do the sound processing. Files selected by the user get converted to raw PCM and stored internally to minimize startup time, then oboe handles queueing and playback of the files.

There is also a basic CI/CD setup using Github Actions (it's very basic, it just creates an apk and uploads it to the Play Store ), so if you fork this repo and get automated builds you can easily tweak that to your needs - just add your own secrets.

Please be aware: This is a hobby project, and I work on this very infrequently in my very limited spare time. This is often visible in the code base (and, for example, its lack of test coverage). So if you're looking for examples or a reference how to do something, don't use this!!! Come back in 3 to 5 years, by then I should have cleaned up most of it :-) (Of course, if you feel inclined to help improve this, I am happy to merge any usefull pull requests).
