Advanced configuration

Once the control panel has been switched to advanced mode, things begin to look a little more complicated. The device list is now expandable and you can enable more than one item at a time.

Device list items explained:

Devices are independent hardware units most of the time. It is easy to understand the concept of audio devices, as the term in this context means exactly what common sense would suggest.
Each audio device has one or more Device Interfaces (sometimes also called “filters” by Microsoft.) They represent physical sub units of a Device. If a Device has just one single Device Interface, this Interface will not be shown. Selecting a Device – in this case – would also select its Interface. In our example, the single Interface of the last Device in the list is hidden. The visible input(🎤) and output(🔈) items are not Interfaces, but rather so-called “Pins”.
Each Interface has one or more Pins. Each Pin represents a single in-bound or out-bound audio stream. If an Interface has just one single Pin, this Pin will not be shown. Selecting an Device/Interface – in this case – would also select its Pin. In our example, the Interfaces of the first Device in the list are shown, but the Pins are hidden.

Note: It is perfectly possible to use ASIO4ALL without having understood any of the above!

  • Device aggregation

    Device aggregation

    Using the button next to each entry, you can now selectively enable/disable each particular item in the device list. This way, you can also create multi-device-setups (“aggregate devices”) . Multi-device-setups require that all the devices involved are running from the same clock source. You can achieve this by daisy-chaining devices via S/PDIF etc. On-board devices… more

  • Latency Compensation

    Latency Compensation

    Since ASIO4ALL does not have sufficient knowledge of the underlying hardware/driver architecture, it can only guess the actual latencies involved. With these sliders you can compensate for the latencies unknown to ASIO4ALL such that recordings in your sequencer software are properly aligned with the rest. Note: In multi-device-setups the largest respective value of all devices… more

  • Hardware buffer

    Hardware buffer

    Note: For WaveRT drivers, this box is labeled “Allow Pull Mode (WaveRT)” instead! Enables the hardware buffer for the highlighted device. This only works for so called “WavePCI” miniports, as other types of WDM drivers do not usually allow direct access to the hardware buffer. Adjustment for best hardware buffer performance involves the “ASIO Buffer… more
