FlexASIO differentiates itself by using an intermediate library called PortAudio that itself supports a large number of operating system sound APIs, which includes Kernel Streaming and WASAPI (in shared and exclusive mode), but also the more mundane APIs MME and DirectSound. Thus FlexASIO can be used to interface with any sound API available on a Windows system. For more information, see the backends documentation.

Among other things, this makes it possible to emulate a typical Windows application that opens an audio device in shared mode. This means other applications can use the same audio devices at the same time, with the Windows audio engine mixing the various audio streams. Other universal ASIO drivers do not offer this functionality as they always open audio devices in exclusive mode.
