Oboe

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
