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

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
