More complex functions can be constructed in a modular way by cascading several filters together to form a filter graph. The operating system connects the filters to other filters to form filter graphs that process audio streams on behalf of application programs. A client instantiates an input or output pin on a filter when the client needs to route a data stream into or out of that filter. The output pin of the upstream filter is connected to the input pin of the downstream filter. Each pin factory is capable of instantiating pins of a particular type.

There are no open issues. If the filter can provide one or more pins that are similar or identical in function, the filter groups those pins together into the same pin factory.
An adapter driver exposes a collection of filter factories to the audio system. Feedback We’d love to hear your thoughts. In some contexts, the terms pin and stream can be used interchangeably. If the adapter contains one or more devices that are similar or identical in function, the driver groups the filters for those devices together into the same filter factory.
In this model, an audio adapter can be viewed as a collection of hardware devices, and the adapter driver exposes each of these devices to the audio system as an individual filter. Note that the term KS filter must be distinguished from the term filter driverwhich is another WDM concept. More complex functions can be constructed in a modular way by cascading several filters together to form a filter graph.
This section contains the following topics: The data stream from the output pin must have a data format that the input pin can accept. The functionality can be implemented in software or in hardware. If the adapter contains several different types of devices, those devices are presented through several different filter factories.
A client instantiates audiodrife input or output pin on a filter when the client needs to route a data stream into or out of that akdiodrive.
Each pin factory is capable of instantiating pins of a particular type. A pin on an audio filter can be thought of as audiodrice audio jack. Kernel streaming KS services support kernel-mode processing of data streams for audio and for other types of continuous media.
Our new feedback system is built on GitHub Issues. A typical audio adapter card might contain audio devices for playing a wave stream through a set of speakers, converting wudiodrive audio signal from a microphone to a wave stream, and synthesizing sound from a MIDI stream. For updates and information about new features of the WDM audio architecture, see the audio technology website.
Introduction to WDM Audio Drivers
Choose the type you’d like to provide: The output pin of the upstream filter is connected to the input pin of the downstream filter. Upper- and lower-level filter drivers reside above and below the function driver, respectively. The adapter driver can wrap each of these audio devices in a KS filter that it exposes to the operating system.
In this section, the term filter refers to a KS filter rather than a filter driver unless noted otherwise. Conceptually, a stream undergoes processing as it flows along a data path containing some number of processing nodes.
Each filter factory is capable of instantiating filters of a particular type: KS services are built upon audiodeive Windows Driver Model. KS filters are connected together through their pins. Each filter factory is capable of instantiating filters of a particular type:.

A KS filter exposes a collection of pin factories to the audio system. Data buffering is typically required to smooth out momentary mismatches in the rates at which an output pin produces data and an input pin consumes it. Product feedback Sign in to give documentation feedback. Vendor Audio Driver Options. You may also leave feedback directly on GitHub. For example, a filter that performs audio mixing might have one pin factory that can instantiate a single output pin and a second pin factory that can instantiate several input pins.
The operating system audiodgive the filters to other filters to form filter graphs that process audio streams on behalf of application programs.
