Added support for 3D virtual surround rendering in ALWrapper #32
Conversation
This adds support for generic head related transfer functions 3d virtual surround when set to @"high", with a special optimised @"headphones" mode offering a more specialised HRTF 3D virtual surround rendering

Awesome! Thanks for contributing! |

Looks like despite the presence of APIs explicitly talking about HRTF stuff, setting the render quality to high is no different from low, and doesn't enable any HRTF functionality. Setting it to 'headphones' does something weird which I've yet to figure out, but it also doesn't seem to provide spatialization - though it does totally screw up panning. Maybe sensible to revert this. wtf openal-ios :( |

I should probably test this on the actual device. Simulator tends to suck for audio! |

I get the same behaviour where low and high quality are the same. I was able to get a nice spatialization effect using "headphones" on iOS 5 but in iOS 6 with the same code when I turn on "headphones" the output goes silent (both in the simulator and on actual devices). |
allows users to enable HRTF-based 3D virtual surround sound, at the expense of higher CPU usage
