The WDM Device List lets you choose which audio hardware ASIO4ALL exposes to an audio application. ASIO4ALL provides an ASIO driver interface for standard Windows audio devices, giving recording and music software a way to work with them at lower latency.
Select active audio devices in the WDM Device List
Choose the playback or recording devices ASIO4ALL should make available to your audio software. The list displays detected devices; selecting one lets you adjust its settings, and device changes apply to the currently highlighted entry. After enabling the desired hardware, select ASIO4ALL as the driver in the audio application's configuration.
Adjust the ASIO buffer for your audio workload
The ASIO Buffer Size control changes how much audio is processed in each buffer. Smaller buffers can reduce the delay between playing or recording and hearing the result, while a setting that is too demanding for the computer or device can cause interruptions. Adjust the buffer from ASIO4ALL's control panel while working in the audio application.
Use advanced controls for device behavior
Switch to advanced mode to access settings for more involved audio configurations. Device aggregation can combine selected audio devices, while latency compensation and alternative buffer synchronization provide controls for timing and synchronization behavior.
- Buffer Offset adjusts the buffer behavior for a selected device.
- Always Resample 44.1↔48 kHz addresses audio devices running at those sample rates.
- Low Power Mode is available as an additional operating setting.
Configure ASIO4ALL inside the audio application
Open the application's audio configuration and choose ASIO4ALL as its ASIO driver. Use the driver's control-panel button to open the device list and buffer controls. The audio application and ASIO4ALL settings work together: the application selects the driver, and ASIO4ALL controls which detected devices are active.
Pros
- Adds ASIO support for WDM audio devices
- Device selection is available in the WDM Device List
- Advanced settings include buffer and synchronization controls
Cons
- Results depend on the capabilities of the underlying audio driver and device
System requirements: Windows 10, Windows 11
What does ASIO4ALL do?
It provides an ASIO driver interface for standard Windows audio devices, allowing compatible audio software to use them with adjustable buffering.
How do I select an audio device?
Open the ASIO4ALL control panel from your audio application's audio settings, then enable the device in the WDM Device List.
What does the ASIO Buffer Size setting change?
It sets the audio buffer size. Smaller buffers can lower delay, but may cause interruptions if the system or device cannot keep up.
