FlexASIO alternatives
FlexASIO is a free, open-source ASIO driver designed for Windows systems, offering compatibility across a wide range of audio hardware. Unlike some similar drivers, it leverages the PortAudio library to support multiple audio APIs, including Kernel Streaming, WASAPI, MME, and DirectSound. This design allows for shared audio device access, enabling simultaneous use by different applications, a feature typically unavailable in exclusive-mode ASIO drivers.
