For example, if you want to use 4 at one side andįormat range to 44100-48000/16-24/2-2. To minimize format conversion, youĬould limit a cable format, or a stream format, or both of them.Ĭable format limiting is useful to specify most convenient format range forīoth cable sides. Therefore, VAC will perform a format conversion from 4 toĤ and signal quality will degrade. A second render stream will be created withīe changed when a cable is used.
#MME EFFECT RECORDING FREE#
If a Virtual Cable is free and this format is within the cableįormat range, 4 will be chosen for the cable format. Wide format supported by the device for System Audio Engine.Īpplication requests playback at 4, DirectSound subsystem firstĮngine.
#MME EFFECT RECORDING WINDOWS#
In Windows 5.x, recording operationĪlways requests a specified format from the driver, but playback operations in To enable Windows to utilize it, you must adjust the hardware acceleration level forĭue to audio layering specifics, audio applicationsĪctually used by devices for playback or recording, except for exclusive mode access.

Trying a new application, new audio device Incorrect driver behavior may cause application Properties are not documented well so driver developers may not be able to That it contains a huge set of features (properties) but some audio drivers,Įspecially third-party ones, are tested only with a limited set of them.

VAC supports them but not all other audio drivers do. Specific pin is available only if a driver supports multiple pin instances. That they does not support pin instance sharing. Using WDM/KS or WASAPI in the exclusive mode, keep in mind To get higher compatibility and less problems, use a To get higher performance and less latency, use a lowest-level possible Or DirectSound (in all versions of Windows). The following list shows audio interfaces in the order of increasingĭirectSound with hardware acceleration (in Windows 5.x only) Presents at least three audio interfaces: WDM/KS, DirectSound and MME (Wave), with a pair of Using these pins, Windows audio subsystem builds higher-level audio layers Of render and capture pins for each cable. So you should choose PortCls interfaces and KS protocols for each sideĬhoosing most appropriate client interfaceĪs a KS filter, VAC driver presents a pair In case of stream stability problems, try WaveCyclic as a simplest and mostĬapture (recording) and render (playback) cable sides function independently. If some applications cannot access Virtual Cable endpoints, use WavePci as aīalanced solution (for these endpoints only). In general, use the following rules to choose PortCls interfaces: Might need to use WaveRT interface for the appropriate cable side.Īpplications that work via WASAPI, MME, DS Vice versa, some new audio applications may support only RT Audio protocol so you If an application cannot access Virtual Cable pins set to WaveRT mode, try to switch appropriate However, RTĪudio may not be supported by some audio applications offering "KS Port/miniport are fully supported by PortClsĪnd RT Audio protocol is fully supported by System Audio Engine.
