OpenAL for Android Sample

At this point, it is hard to find some working examples of 3D audio/spatialization on the Android platform that could be easily prototyped. Hence, I shared this sample application showing 3D audio rendering, using the bit old openAL4android library.

Hope it helps!

Ready For

• Android SDK v26.0.0
• Android Studio v2.3.3
• Gradle Plugin v2.3.3
• Tested On:
  • Android 7.0 Nougat
  • Android 6.0 Marshmallow

Remarks

• IMPORTANT: to make a compatible .wav file, the RIFF WAVE headers should be present on the file. Common audio/video conversion libraries tried (sox, ffmpeg) does not trivially generate the proper .wav file headers. Only Audacity for Windows 10 did the trick.
• libopenal.so and libopenalwrapper.so are compiled for 32-bits platforms (ARMEABI v7a).
• gradle.properties includes the android.useDeprecatedNdk=true option which may not be available in future versions of Android Gradle plugin.
