WDM vs MME – Which Driver is BEST for You? (All Scenarios Compared!)

When it comes to audio drives, Windows offers its customers a variety of choices. These choices allow you to select the most appropriate driver for your work.

Among the well-known OS audio drivers are MME and WDM. An internal sound card can swiftly broadcast sounds through the OS. 

As opposed, ASIO may stream audio without first needing the OS’s assistance to process it. You will learn about the distinctions between the drivers in this article. You will also learn the differences between WDM, MME, ASIO, and MME.

Difference Between WDM vs MME

WDM, which stands for “Windows Driver Model,” has better latency effectiveness than traditional types of drivers exclusively on Windows-based systems.

It is a framework that enables audio drivers to connect with the Windows kernel, a vital component of the operating system, rather than really being an audio driver.

It is referred to as kernel streaming. It is the accepted Audio format in most applications, like your web browser, iTunes, and other media players. Many video games will employ this protocol. 

Since the Windows driver paradigm forms the basis for all audio drivers to be integrated into Windows, you can technically stop thinking of it as an audio driver.

WDM is frequently referred to as kernel broadcasting because it is the essential component of the operating system. 

Most apps, including iTunes, web browsers, and other media players, use this driver architecture as a standard audio application. 

Low-level buffer management is handled by a piece of the WDM’s code in a plug-and-play manner using DMA. Only the color bands—one for each color—in which the signals are conveyed and used for distribution.

Microsoft Multimedia Environment, or MME for short, is supported by practically all PC audio programs. In effect, when Windows 3.1 was released, this was the first audio adapter.

The majority of built-in audio cards use the MME driver protocol. Most PC audio programs support MME.

Your videos and audio can work because of the MME driver for Windows running machines. Microsoft created the MME driver as part of the “Windows with Multimedia Extensions 1.0” operating system.

Sound cards can now be accessed by API using the name MME. This OS makes the flawless operation of sound cards and other devices possible for everyone.

You need a sound card driver API to get at the hardware. The majority of Windows apps use MME to manage sound. The MME is responsible for hosting both the host program and the sound card. 

The multimedia engine can only give the data stream to the multimedia engine, whereas the OS can send data to the card. WDM is a mandatory driver upgrade because of the system’s high latencies.

Operating systems and WDM are intertwined in many ways. By invoking network service functions and modifying operating system entities, drivers communicate effectively with the operating system since WDM drivers are regarded as reliable kernel-mode components.

Essential Functions of a WDM Audio Driver

The driver provides information on all input and output stream types it can handle, together with the number of instances of each stream type.

The driver provides this information through a list of pin factories and the maximum number of pins each factory can produce. 

For example, an easy audio device might input and output a single PCM audio stream.

The filter for this device consists of two pin factories, one for input stream and the other for output stream, each of which supports a single pin instance.

If one of these sensors is on the adapter card, the adapter driver offers a filter factory with just that one instance of a filter. The driver supports one or more property sets.

For instance, while some audio drivers may also support other property sets, all audio drivers must support audio.

Using property requests, clients of the driver can get information about a filter’s capabilities and change the filter’s programmable settings.

The driver offers optional support for a hardware clock. This clock must be readable and writeable for streams to synchronize with other streams on the same or different hardware.

Device Function Drivers

A function driver is the main driver for a device. A function driver, which is required, is typically made by the device manufacturer (unless the device is being used in raw mode). A function driver might take care of one or more devices.

Class drivers

These function drivers belong to a specific class and can be thought of as pre-existing framework drivers, on top of which Miniport and other class drivers can be built.

The numerous tiers of the WDM architecture’s class drivers provide interfaces. The class driver can be designed with shared features that other class and Miniport drivers can use.

The bottom edge of the class driver will have its interface accessible to the Miniport driver, whereas the upper edge of top-level class drivers is operating system-specific.

The loading and unloading of class operators can be done dynamically. Except for bus-type class drivers, they can perform class-specific functions that are not hardware- or bus-specific.

Occasionally, they even do just class-specific parts, such as enumeration.

Miniport drivers

These also function as SCSI, USB, Audio, and network device drivers.

They should be code and binary compatible with Windows 98 and Windows 2000 despite being typically device-specific and controlling access to the hardware through a specific bus class driver.

Windows Driver Model (WDM)

The Windows driver paradigm is more effective than VxD and standardizes minimum needs without requiring much source code. 

However, WDM adapters are backward compatible with Windows 3.1, 95, and NT 4.0 and earlier versions of Windows, including Windows 98. Later versions of the WDM audio protocol are backward compatible.

This drawback is that utilizing drivers made for older OS versions may or may not make it possible for future OS features to work.

Voice Meter Banana WDM

A cutting-edge virtual audio mixing application that offers you total control over all input and output sounds on your PC is called Voicemeeter Banana.

Using this effective tool, you can segregate audio sources like music, game loudness, and Discord by allowing you to adjust each separately.

You can improve the sound on your PC by using an audio mixer application called Voicemeeter Banana. It can be used to modify the audio of your music, games, and movies. There are several possibilities available.

Voicemeeter Banana is a variation of the software designed for Windows. It’s interesting to observe that Voicemeeter Banana gives you a comparable option, albeit with more freedom than Voicemeeter.

Voicemeeter Banana is a more modern software than Voicemeeter for Vb audio. It can be used free to handle several different things, including audio hardware, audio devices, and other applications.

It allows you to effortlessly control audio files and the input and output from many audio computer systems.

The Voicemeeter banana also features a modulation control and a complete parametric EQ. Compared to Voicemeeter, which has fewer eq adjustment options, this offers more opportunities to enhance the sound quality.

In taking everything into account, Voicemeeter banana allows you to improve the audio quality of your audio input devices while streaming or engaging in video game play to provide your audience with the most satisfactory experience possible. Control any audio sources with it.

Manage the streaming audio on your Windows PC with Voicemeeter Banana

If you’re a broadcaster, the Windows version of the Voicemeeter Banana donationware program might answer all your audio problems. 

The audio control in Windows 10 can occasionally be a little complicated, especially if you want to route the audio through many different devices or apps.

Controlling which audio travels is crucial for streamers to avoid a terrible stream.

Some hardware options, such as an outboard mixing deck, can handle everything for you. These are fantastic; however, they are expensive and require numerous cables.

The free Windows program Voicemeeter Banana, which simulates a mixing deck inside your computer, might work better for you. It is fantastic. A slight learning curve does exist, though.

Setting up Voicemeeter Banana

Before continuing, you must download Voicemeeter Banana for Windows and get a complimentary virtual audio cable. You’re entitled to one without charge, and you’ll learn why it’s crucial in the following steps.

Unzip the zip file that contains this to get the executable for your particular version of Windows (x86 or x64).

Before you start tinkering, ensure Voicemeeter Banana is configured as your default audio device for Windows 10. The app will therefore serve as the hub for everything.

Adding your output devices

Before you can hear audio from your PC, you must configure any necessary gear. Each of the three outputs (A1, A2, and A3) has a corresponding control.

Examining the colored boxes in those mentioned above may determine which links with which.

Three different hardware devices that you might own can receive audio from Voicemeeter. In my case, earbuds, a gaming headset, and a set of desktop speakers can all be connected to an output.

When you select the appropriate output, a list of all the audio-capable devices connected to your PC will appear. Additionally, you’ll see that everything is repeated twice and is preceded.

Choose the audio device with WDM next to it first, then switch to MME if there are any problems. But you have to be consistent at all times.

The same rule applies to audio input devices; input and output must be compatible. WDM for WDM or MME for MME.

You can customize each audio output using the slider and surrounding choices in the Voicemeeter Banana window’s bottom right.

If desired, you can mute each track independently, add EQ settings, or change from stereo to mono in addition to the wide range of volume adjustments available on the slider.

Setting up your audio inputs

The left side of the window is where you choose an input device, much like you do when picking outputs.

In this case, using the free virtual audio wire mentioned earlier is crucial because it allows you access to a second input. If you want more, stack them up and pay the developer some money.

The fundamental concept is the same as it was with outputs. In this case, a hardware-based input is not necessary.

You can instruct Voicemeeter Banana to deliver an application from your PC into the mixer as though it were hardware via the virtual cable.

Your microphone should be the first piece of hardware you connect, ensuring it matches WDM or MME.

The following can be either hardware or software, as you like. You only need to instruct the appropriate program to use the digital wire as its output to accomplish this with the Xbox app, Skype, or Discord.
