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.

  • Kernel buffers/Buffer offset

    Kernel buffers/Buffer offset

    If hardware buffering is disabled, this control lets you add up to two more buffers to be queued for audio output. Each additional buffer increases the output latency of the device by the time it takes to play one buffer. Therefore, the initial setting of “2” should only be changed on less powerful machines, where… more

  • Allow Pull Mode

    Allow Pull Mode

    There are two basic access methods for a WaveRT device, “pull-mode” (also called “event-mode”) and “push-mode” (also called “polling mode”). If this box is left unchecked, ASIO4ALL will not use “pull-mode”, otherwise it will use it whenever possible. The default mode will be polling, though, because it is the most compatible one. Especially for small… more

  • Always resample 44.1◀▶48kHz

    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… more
