After a user installs a 3rd party ASIO driver, applications can send data directly from the application to the ASIO driver. However, if an application opens an endpoint in Exclusive Mode, then there is no other application that can use that endpoint to render or capture audio.ДЄnother popular alternative for applications that need low latency is to use the ASIO (Audio Stream Input/Output) model, which utilizes exclusive mode.

In that case, the data bypasses the Audio Engine and goes directly from the application to the buffer where the driver reads it from. The audio stack also provides the option of Exclusive Mode. The application is signaled that data is available to be read, as soon as the audio engine finishes with its processing.

In Windows 10, the latency has been reduced to ~0ms for all applications. It also loads audio effects in the form of Audio Processing Objects (APOs).Д«efore Windows 10, the latency of the Audio Engine was equal to ~6ms for applications that use floating point data and ~0ms for applications that use integer data. The Audio Engine reads the data from the buffer and processes them.

Starting with Windows 10, the buffer size is defined by the audio driver (more details on this below). The driver reads the data from the H/W and writes the data into a buffer.Д«efore Windows 10, this buffer was always set to 10ms. The H/W has the option to process the data (i.e. Here is a summary of latency in the capture path: The H/W also has the option to process the data again (in the form of additional audio effects). The Audio driver reads the data from the buffer and writes them to the H/W. Starting with Windows 10, the buffer size is defined by the audio driver (more details on this are described later in this topic). The Audio Engine writes the processed data to a buffer.Д«efore Windows 10, this buffer was always set to ~10ms. In Windows 10, the latency has been reduced to 1.3ms for all applications The latency of the APOs varies based on the signal processing within the APOs.Д«efore Windows 10, the latency of the Audio Engine was equal to ~12ms for applications that use floating point data and ~6ms for applications that use integer data For more information about APOs, see Windows Audio Processing Objects. It also loads audio effects in the form of Audio Processing Objects (APOs). The Audio Engine reads the data from the buffer and processes it. The application writes the data into a buffer Here is a summary of the latencies in the render path: The following diagram shows a simplified version of the Windows audio stack. It is equal to render latency + touch-to-app latency. It is roughly equal to render latency + capture latency.Дelay between the time that a user taps the screen until the time that the signal is sent to the application.Дelay between the time that a user taps the screen, the event goes to the application and a sound is heard via the speakers.

Changes in WASAPI to support low latency.Дelay between the time that an application submits a buffer of audio data to the render APIs, until the time that it is heard from the speakers.Дelay between the time that a sound is captured from the microphone, until the time that it is sent to the capture APIs that are being used by the application.Дelay between the time that a sound is captured from the microphone, processed by the application and submitted by the application for rendering to the speakers.

Provide a reference on how application developers and hardware manufacturers can take advantage of the new infrastructure, in order to develop applications and drivers with low audio latency.

Explain the changes that reduce audio latency in the WindowsВ 10 audio stack.

Describe the sources of audio latency in Windows.

WindowsВ 10 includes changes to reduce the audio latency.

Having low audio latency is very important for several key scenarios, such as the following. OverviewДЄudio latency is the delay between that time that sound is created and when it is heard. It covers API options for application developers as well as changes in drivers that can be made to support low latency audio. This topic discusses audio latency changes in WindowsВ 10.
