16 de fev. de 2022 · Use the slider to adjust the ASIO buffer size for the device currently highlighted. Smaller buffer size means lower latency. Once you hear crackles or audio becomes distorted, you need to increase the buffer size. ASIO buffer size directly relates to audio latency. Thus, you want to get a rather small value here.

ASIO is a trademark and software of Steinberg Media Technologies GmbH
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.
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 exclusive mode.
•Windows Vista or later
•Compatible with 32-bit and 64-bit ASIO Host Applications
After running the installer, FlexASIO should appear in the ASIO driver list of any ASIO Host Application (e.g. Cubase, Sound Forge, Room EQ Wizard).
The default settings are as follows:
•DirectSound backend
•Uses the Windows default recording and playback audio devices
•32-bit float sample type
•20 ms "preferred" buffer size
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.
FlexASIO welcomes feedback. Feel free to file an issue in the GitHub issue tracker, if there isn't one already.
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.
The biggest difference between asio4all and real asio seems to be lag introduced by directx. If you intend to switch to Linux, make sure, your card is supported. Others already mentioned "Class compliant" - yes, that helps. Here is a list of supported Hardware.
Something similar to ASIO on Linux that isn't WineASIO. So I've been considering switching to Linux for quite some time (messing around with Debian on a virtual box at least) and I've got all my bases covered except for one thing: what low-latency soundcard driver protocol would I use on Linux?
19 de jan. de 2022 · Using the button next to each entry, you can now selectively enable/disable each particular item in the device list. This way, you can also create multi-device-setups (“aggregate devices”). Multi-device-setups require that all the devices involved are running from the same clock source.
