+@item object-oriented C++ design
+@item simple, common API across all supported platforms
+@item only one source and one header file for easy inclusion in programming
+@item allow simultaneous multi-api support
+@item support dynamic connection of devices
+@item provide extensive audio device parameter control
+@item allow audio device capability probing
+@item automatic internal conversion for data format, channel number
+compensation, (de)interleaving, and byte-swapping
