This is not a simple library to wrap as it is a C++ library. It is possible (iXUI2D wraps a C++ library) however it is more complicated than wrapping regular libraries.
if so bad news for me. i successfully wrapped it on B4A and now i would port my app on Iphone. I use that library to real time capture / play byte buffers of audio data (MP3, OPUS, AAC). I think this is not possible to do with standard libraries of B4I?
