What started as a bedroom project in early 2003 – for the sole purpose to get ASIO support for the AC97 on my laptop – has become ASIO4ALL – the universal ASIO driver for WDM audio. Honestly, I did not expect this project to become as popular as it has become (but this popularity would not particularly disappoint me, either 😉

ASIO4ALL is a hardware independent low latency ASIO driver for WDM audio devices. It uses WDM Kernel-Streaming and sometimes even more sophisticated methods to achieve its objectives.

In order to use ASIO4ALL, you need:

• A WDM-compatible operating system, (any Windows OS since Win98SE). Beginning with version 2.15, Windows 10 or later will be required.
• A WDM-driver for your audio hardware, whereas all audio device drivers are WDM drivers, except sometimes under Win98SE/WinME.
• A couple minutes of your time and a little bit of luck.

What ASIO4ALL will NOT do:

• Replace your existing sound card drivers or mess with them in any way.
• Install any kernel mode components that could potentially affect the stability of your system.
• “Overclock”, or otherwise operate your audio hardware in ways that could potentially be harmful and/or void your warranty, except, of course, in cases where the manufacturer of your hardware has specifically stated that the use of ASIO4ALL would void your warranty indeed.
