Introduction

Welcome to ASIO4ALL! This manual enables you to make the most of your ASIO4ALL installation, especially as it comes to the advanced features newly introduced in this Version of ASIO4ALL.

In order to achieve the best possible results with ASIO4ALL on a very old computer, it is recommended that your computer is configured accordingly:

  • When running an old version of Windows, set the power scheme to “Always On” (XP) or “High Performance” (Vista) in order to turn off Processor P-State switching! Advanced: Modify an existing power scheme so as to not switch CPU speed, because other power settings are not that critical.
  • Turn off system sounds! While e.g. the Windows logon sound certainly will not be a problem, sound effects in response to button clicks, notifications etc. will mean that for the time they play, ASIO4ALL may be unable to initialize the audio device.

Note: Fortunately these issues are less important, should you be using a version of Windows that is less than 10 years old! You should not need to re-configure your system, then.

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
