FlexASIO is a universal ASIO driver, meaning that it is not tied to specific audio hardware. Other examples of universal ASIO drivers include ASIO4ALL, ASIO2KS, ASIO2WASAPI.
FlexASIO is a universal ASIO driver designed to provide low-latency audio processing without being tied to specific audio hardware. Unlike hardware-specific drivers, FlexASIO leverages the PortAudio library to interface with various sound APIs available on Windows systems, including WASAPI (shared and exclusive modes), Kernel Streaming (KS), DirectSound, and MME.
Key Features:
Cross-platform support for both 32-bit and 64-bit ASIO host applications.
Configuration flexibility through an optional settings file for customizing audio backends, buffer sizes, and sample formats.
Logging capabilities to troubleshoot driver initialization and operation.
A device list program (PortAudioDevices.exe) for diagnosing audio hardware compatibility.
Ideal for audio professionals, content creators, and developers requiring ASIO functionality without the need for dedicated hardware drivers. FlexASIO offers unparalleled flexibility in integrating with diverse audio systems while maintaining low-latency performance. It can be installed via winget for seamless setup.
FlexASIO is a universal ASIO driver, meaning that it is not tied to
specific audio hardware. Other examples of universal ASIO drivers include
ASIO4ALL, ASIO2KS, ASIO2WASAPI. KoordASIO is a derivative of
FlexASIO that focuses on WASAPI and user convenience.
Universal ASIO drivers use hardware-agnostic audio interfaces provided by the
operating system to produce and consume sound. The typical use case for such a
driver is to make ASIO usable with audio hardware that doesn't come with its own
ASIO drivers, or where the bundled ASIO drivers don't provide the desired
functionality.
While ASIO4ALL and ASIO2KS use a low-level Windows audio API known as
Kernel Streaming (also called "DirectKS", "WDM-KS") to operate, and
ASIO2WASAPI uses WASAPI (in exclusive mode only), 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
.

Troubleshooting
The FAQ provides information on how to deal with common issues. Otherwise,
FlexASIO provides a number of troubleshooting tools described below.
Logging
FlexASIO includes a logging system that describes everything that is
happening within the driver in an excruciating amount of detail. It is
especially useful for troubleshooting driver initialization failures and
other issues. It can also be used for verification (e.g. to double-check
that FlexASIO is using the device and audio format that you expect).
To enable logging, simply create an empty file (e.g. with Notepad) named
FlexASIO.log directly under your user directory (e.g.
C:\Users\Your Name Here\FlexASIO.log). Then restart your ASIO Host
Application. FlexASIO will notice the presence of the file and start
logging to it.
Note that the contents of the log file are intended for consumption by
developers. That said, grave errors should stick out in an obvious way
(especially if you look towards the end of the log). If you are having
trouble interpreting the contents of the log, feel free to
ask for help.
Do not forget to remove the logfile once you're done with it (or move
it elsewhere). Indeed, logging slows down FlexASIO, which can lead to
discontinuities (audio glitches). The logfile can also grow to a very
large size over time. To prevent accidental disk space exhaustion, FlexASIO will
stop logging if the logfile exceeds 1 GB.
Device list program
FlexASIO includes a program that can be used to get the list of all the audio
devices that PortAudio (and therefore FlexASIO) knows about, as well as detailed
information about each device.
The program is called PortAudioDevices.exe and can be found in the x64
(64-bit) or x86 (32-bit) subfolder in the FlexASIO installation
folder. It is a console program that should be run from the command line. It
doesn't matter much which one you use.
Test program
FlexASIO includes a rudimentary self-test program that can help diagnose
issues in some cases. It attempts to emulate what a basic ASIO host
application would do in a controlled, easily reproducible environment.
The program is called FlexASIOTest.exe and can be found in the x64
(64-bit) or x86 (32-bit) subfolder in the FlexASIO installation
folder. It is a console program that should be run from the command
line.
It is a good idea to have logging enabled while running the test.
Note that a successful test run does not necessarily mean FlexASIO is
not at fault. Indeed it might be that the ASIO host application that
you're using is triggering a pathological case in FlexASIO. If you
suspect that's the case, please feel free to ask for help.
When asking for help, it is strongly recommended to produce a log
while the problem is occurring, and attach it to your report. The output of
FlexASIOTest, along with its log output, might also help.
