[TODO]

• Compile for Android. Use the following command as a starting point:

  cmake \
    -DCMAKE_TOOLCHAIN_FILE=$NDK_PATH/build/cmake/android.toolchain.cmake \
    -DANDROID_ABI=arm64-v8a \
    -DANDROID_PLATFORM=android-21 \
    --build .

• Tidy up the code. Make it more readable

• Create a better demo Godot project

• Add error handling

• Remove hard-coded buffer size, block size, sample rate, etc. and make them all configurable from within the Godot editor. We should get the sample rate from Godot.

• Do something with pitch_scale parameter sent from Godot for Doppler effect.

• Better understand the _mix method and its arguments.

• See if/where AudioServer::get_singleton()->lock(); is really necessary.

• Improve log messages
