Oboe is a C++ library which makes it easy to build high-performance audio apps on Android. It was created primarily to allow developers to target a simplified API that works across multiple API levels back to API level 16 (Jelly Bean).

## Features
- Compatible with API 16 onwards - runs on 99% of Android devices
- Chooses the audio API (OpenSL ES on API 16+ or AAudio on API 27+) which will give the best audio performance on the target Android device
- Automatic latency tuning
- Modern C++ allowing you to write clean, elegant code
- Workarounds for some known issues
- [Used by popular apps and frameworks](https://github.com/google/oboe/wiki/AppsUsingOboe)
