What is KS WDM?

Table of Contents

WDM Audio Drivers Overview – Windows drivers Windows Driver Model (WDM) audio drivers make use of the kernel streaming (KS) components, which operate in kernel mode and are part of the operating system.

What does KS mean in Voicemeeter?

Best audio performances are given when using audio device in exclusive mode. This is what Voicemeeter does when selecting WDM (WASAPI) audio output devices (or KS). In this case, no other application might be able to use the same audio device, and then might need to be connected to Voicemeeter virtual input instead.

What is a KS audio device?

MME is an older and widely supported Windows audio driver. KS stands for kernel streaming. Another important bit of software here is WASAPI, meaning Windows Audio Session API, that will come in handy in a second.

Should I use WDM or MME?

Having a weird issue where the audio will sound as if someone is talking through a fan (as if the audio is being chopped up) when selecting WDM, but selecting MME is fine. This happens when ANY audio is coming through, even just watching a YT video or listening to Spotify.

Why does ASIO sound better?

Steinberg designed this format to improve latency performance and channel count compared to Windows Audio drivers. ASIO allows the software to bypass Windows Audio and gives direct communication to the hardware. This is the preferred driver mode for all professional recording and audio applications.

Should I use MME or WDM for Voicemeeter?

Voicemeeter will use your WDM output devices in Exclusive Mode. This avoids other applications to use the device at the same time. In contrast, MME uses the output device in Shared mode (other applications can use it simultaneously).

Should I use Voicemeeter?

Voicemeeter is useful, if you need to output audio to more devices or apps than just OBS. If you’re just recording, this is usually not the case. Or if you’re just streaming what is running on your PC. With such simple setups, audio is fed into OBS, and OBS mixes it fine and outputs it to recording or stream.

Does Voicemeeter banana have a compressor?

Boost your voice and manage noisy talk with easy-to-use knobs! The Compressor can make the input signal dramatically louder and assertive.

What is the difference between WDM KS and MME?

WDM stands for “Windows Driver Model,” which has improved performance in latency over standard type drivers in Windows based systems only. MME stands for “Microsoft Multimedia Environment,” and is supported in almost all PC audio applications.

What is a WDM audio driver?

Windows Driver Model (WDM) audio drivers make use of the kernel streaming (KS) components, which operate in kernel mode and are part of the operating system. Hardware vendors should make several design decisions before beginning development of a Windows-based audio hardware device.

What are the kernel-mode Microsoft Windows Driver Model (WDM) audio components?

The kernel-mode Microsoft Windows Driver Model (WDM) audio components are: Port Class Adapter Driver and PortCls System Driver USB Audio Class System Driver (Usbaudio.sys) The kernel-mode WDMAud system driver (Wdmaud.sys) is paired with the user-mode WDMAud system driver (Wdmaud.drv).

What is a KS filter in WDM?

Note that the term KS filter must be distinguished from the term filter driver, which is another WDM concept. A filter driver resides in a WDM driver stack and can intercept and modify the I/O request packets (IRPs) that propagate through the stack.
