ASIO4ALL Official Home

Universal Windows ASIO Driver

Version 2.10 Released!

Combined 32/64 bit version, supports Win 98SE/ME/2k/XP/MCE/2003/XP64 and Vista/Windows 7 x86/x64

Fix a number of relatively minor application compatibility problems.
Remove item redundancies in the GUI WDM device tree. Fix issue that certain configurations (e.g. “Disable all outputs”) would not be saved/restored.
Improve audio device surprise removal recovery. Now typically the response to removal/re-insertion of an (USB, …) audio device would be to recover from the event and resume audio streaming.
Workaround for full-duplex issue with Realtek HD audio drivers on certain Acer laptops.
General, but minor performance improvements under Vista and Win7.
Default audio device configuration changed to skip HDMI audio.

ASIO4ALL always aims to use the buffering algorithm most suitable for any particular device. This option lets you override the automed pick and select an alternative buffering scheme, where available. Use this

Buffer Offset

This slider affects the circular buffer read/write cursor position of the current WaveRt pin. The adjustable range equals the size of the entire circular buffer. The offset is relative to the cursor position as calculated by ASIO4ALL. In the unlikely event that some manual adjustment is required, you can try to find a better cursor

Always Resample 44.1<->48 kHz

ASIO4ALL can do real time resampling of 44.1 kHz audio to/from 48 kHz. Resampling will automatically take place whenever ASIO4ALL is opened for 44.1 kHz and the WDM driver does not support this sample rate. There may, however, be instances in which case an audio device will support 44.1 kHz only by resampling internally. More
