What is WDM KS and MME?

What is WDM KS and MME?

MME is an older and widely supported Windows audio driver. WDM is a kernel streaming platform which came a bit later, still very widely used. 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.

Does focusrite use ASIO?

The Focusrite Interfaces all come with a native device specific driver that includes both ASIO and WDM driver types. ASIO4all is designed for units that do not have native ASIO Device Drivers, like your computer’s built in audio.

How does a WDM work?

WDM uses a single fiber to transmit multiple optical signals. It does this by breaking up the signal into different frequencies or wavelengths of color. The various wavelengths indicate that different amounts of data are being transmitted simultaneously.

How do I turn off WDM exclusive mode?


  1. Right-click on the speaker icon in the system tray and select Playback devices.
  2. Select the device you want to listen to Audible with and click Properties.
  3. Under the Advanced tab, uncheck Allow applications to take exclusive control of this device.
  4. Click OK to save your device’s settings.

Does ASIO sound better?

Contrary to popular “audiophile” claims, there are NO benefits from using ASIO as far as music playback quality is concerned, while bugs in ASIO drivers may severely degrade the performance.

Do I need ASIO?

ASIO4All is perfect if all you need is playback from the DAW, but you don’t have an audio interface connected. I have occasionally used it that way myself, to play some mix in the DAW when I had my laptop with me but, for some reason, none of my audio interfaces around.

Does Scarlett 2i2 have ASIO?

No, the 2i2 has a terrible ASIO driver. It’s three times slower than RME USB interfaces at the same sample rate/buffer size and around two times slower than any “average” competing USB interface. (It’s even slower than the Access Virus TI running in interface mode, and that’s a USB 1.0 device.)

Where is WDM used?

Wavelength division multiplexing, WDM, has long been the technology of choice for transporting large amounts of data between sites. It increases bandwidth by allowing different data streams to be sent simultaneously over a single optical fiber network.

What are the advantages of WDM?

Advantages of WDM:

  • Easier to reconfigure.
  • Full duplex transmission is possible.
  • It provides higher bandwidth.
  • Optical component are similar and more reliable.
  • High security.
  • This could be the best approach as it is simple to implement.

What is the application of WDM?

The technology of WDM is widely used in Optical Transport Networks. The rapid growth of data service demands a higher quality of the capacity of transmission equipments, network bandwidth and the ability of multi-service transmission.

Should you use exclusive mode?

Exclusive mode is a feature that allows an audio playback program to “talk” directly to the DAC hardware and bypass all the sound processing happening in the OS. The whole purpose of it is to prevent unnecessary processing and resampling. So obviously if you want to run a processor you can’t use exclusive mode.
