Summary

FlexASIO is a universal ASIO driver for Windows that uses the PortAudio library to interface with multiple sound APIs, enabling ASIO functionality on audio hardware without dedicated ASIO drivers.

Features

• Supports various Windows sound APIs: WASAPI (shared and exclusive), Kernel Streaming, DirectSound, and MME.
• Not tied to specific audio hardware, works universally with Windows audio devices.
• Uses PortAudio as an abstraction layer to support multiple backends.
• Enables shared mode operation allowing multiple applications to use the same audio device simultaneously, unlike many other universal ASIO drivers.
• Configurable via a file to adjust buffer size, sample format, backend selection, and audio device choice.
• Includes logging capabilities for detailed debugging and troubleshooting.
• Provides command-line utilities to list audio devices and perform self-tests.

Use Cases

Ideal for users who want to use ASIO drivers with audio hardware lacking manufacturer ASIO support or who require features not available in bundled ASIO drivers.

System Requirements and Compatibility

Compatible with Windows Vista and later versions; supports both 32-bit and 64-bit ASIO host applications.
