A sound card (also known as an audio card) is a computer expansion card that facilitates the input and output of audio signals to and from a computer under control of computer programs. Typical uses of sound cards include providing the audio component for multimedia applications such as music composition, editing video or audio, presentation, education, and entertainment (games).

Dec 19, 2015 However, that takes me back to square one - the problem of using multiple sound cards. Hence my current idea, which involves keeping both the Saffire and Axe plugged in and running the audio outs of both cards to the Mackie Big Knob, which can monitor up to 4 stereo sources simultaneously.

Drivers declare the supported audio signal processing modes for each device.

Available Signal Processing Modes

Audio categories (selected by applications) are mapped to audio modes (defined by drivers). Windows defines seven audio signal processing modes. OEMs and IHVs can determine which modes they want to implement. It is recommended that IHVs/OEMs utilize the new modes to add audio effects that optimize the audio signal to provide the best user experience. The modes are summarized in the table shown below.

Mode	Render/Capture	Description
Raw	Both	Raw mode specifies that there should not be any signal processing applied to the stream. An application can request a raw stream that is completely untouched and perform its own signal processing.
Default	Both	This mode defines the default audio processing.
Movies*	Render	Movie audio playback
Media*	Both	Music audio playback (default for most media streams)
Speech*	Capture	Human voice capture (e.g. input to Cortana)
Communications*	Both	VOIP render and capture (e.g. Skype, Lync)
Notification*	Render	Ringtones, alarms, alerts, etc.

* New in Windows 10.

Signal Processing Mode Driver Requirements

Audio device drivers need to support at least the Raw or Default mode. Supporting additional modes is optional.

It is possible that not all modes might be available for a particular system. Drivers define which signal processing modes they support (i.e. what types of APOs are installed as part of the driver) and inform the OS accordingly. If a particular mode is not supported by the driver, then Windows will use the next best matching mode.

The following diagram shows a system that supports multiple modes:

Windows Audio Stream Categories

In order to inform the system about the usage of an audio stream, applications have the option to tag the stream with a specific audio stream category. Applications can set the audio category, using any of the audio APIs, just after creating the audio stream. In Windows 10 there are nine audio stream categories.

Category	Description
Movie	Movies, video with dialog (Replaces ForegroundOnlyMedia)
Media	Default category for media playback (Replaces BackgroundCapableMedia)
Game Chat	In-game communication between users (New category in Windows 10)
Speech	Speech input (e.g. personal assistant) and output (e.g. navigation apps) (New category in Windows 10)
Communications	VOIP, real-time chat
Alerts	Alarm, ring tone, notifications
Sound Effects	Beeps, dings, etc
Game Media	In game music
Game Effects	Balls bouncing, car engine sounds, bullets, etc.
Other	Uncategorized streams

Hampshire driver download for windows 10. As mentioned previously, audio categories (selected by applications) are mapped to audio modes (defined by drivers). Applications can tag each of their streams with one of the 10 audio categories.

Applications do not have the option to change the mapping between an audio category and a signal processing mode. Applications have no awareness of the concept of an 'audio processing mode'. They cannot find out what mode is used for each of their streams.

WASAPI Code Sample

The following WASAPI code from the WASAPIAudio sample shows how to set different audio categories.

Signal Processing Modes and Effects

OEMs define what effects will be used for each mode. Windows defines a list of seventeen types of audio effects.

For information on how to associate APOs with modes, see Implementing Audio Processing Objects.

It is possible for applications to ask what effects would be applied to a specific stream for either RAW or non- RAW processing. Applications can also ask to be notified when the effects or raw processing state change. The application may use this information to determine if a specific streaming category like communication is available, or if only RAW mode is in use. If only RAW mode is available, the application can determine how much audio processing of its own to add.

If System.Devices.AudioDevice.RawProcessingSupported is true, applications also have the option to set a 'use RAW' flag on certain streams. If System.Devices.AudioDevice.RawProcessingSupported is false, applications cannot set the 'use RAW' flag.

Applications have no visibility into how many modes are present, with the exception of RAW/non-RAW.

Applications should request the optimal audio effect processing, regardless of the audio hardware configuration. For example, tagging a stream as Communications will let Windows know to pause background music.

CLSIDs for System Effects

FX_DISCOVER_EFFECTS_APO_CLSID

This is the CLSID for the MsApoFxProxy.dll “proxy effect” which queries the driver to get the list of active effects;

KSATTRIBUTEID_AUDIOSIGNALPROCESSING_MODE

KSATTRIBUTEID_AUDIOSIGNALPROCESSING_MODE is an identifier to Kernel Streaming that identifies that the specific attribute that is being referenced, is the signal processing mode attribute.

The #define statements shown here, are available in the KSMedia.h header file.

KSATTRIBUTEID_AUDIOSIGNALPROCESSING_MODE is used to by mode aware drivers with a KSDATARANGE structure which contain a KSATTRIBUTE_LIST. This list has a single element in it which is a KSATTRIBUTE. The Attribute member of the KSATTRIBUTE structure is set to KSATTRIBUTEID_AUDIOSIGNALPROCESSING_MODE.

Audio Effects

The following audio effects are available for use in Windows 10.

Audio effect	Description
Acoustic Echo Cancellation (AEC)	Acoustic Echo Cancellation (AEC) improves audio quality by removing echo, after it after it is already present in the audio stream.
Noise Suppression (NS)	Noise Suppression (NS) suppresses noise such as humming and buzzing, when it is present in the audio stream.
