What does this mean ? Does it mean that I can now make generic APOs applyable to any endpoint ? Or does the 1:1 APO/Driver relation still hold ? Regards, /Robert Matthew van Eerde skrev 2013-12-13 01:29:
That's correct. Also, APOs now need to advertise the processing they do by implementing IAudioSystemEffects2::GetEffectsList. The Microsoft Slate Virtual Audio Device Driver sample shows how to register a stream effect, mode effect, and endpoint effect. http://code.msdn.microsoft.com/windowshardware/slate-system-virtual-audio-f241062f/view/SourceCode The Audio effects discovery sample shows how to query audio effects from an app. http://code.msdn.microsoft.com/windowsapps/Audio-effects-discovery-5fd65c15 Relevant Kernel Streaming properties: KSPROPSETID_AudioSignalProcessing / KSPROPERTY_AUDIOSIGNALPROCESSING_MODES KSPROPSETID_AudioEffectsDiscovery / KSPROPERTY_AUDIOSIGNALPROCESSING_MODES Relevant .inf properties: PKEY_FX_StreamEffectClsid, PKEY_SFX_ProcessingModes_Supported_For_Streaming PKEY_FX_ModeEffectClsid, PKEY_MFX_ProcessingModes_Supported_For_Streaming PKEY_FX_EndpointEffectClsid, PKEY_EFX_ProcessingModes_Supported_For_Streaming -----Original Message----- From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of Tim Roberts Sent: Thursday, December 12, 2013 4:13 PM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] Effects APOs I'm hearing from someone who ought to know that LFX APOs have been "deprecated" in Windows 8.1, now replaced by SFX, MFX, and EFX (stream, mode, and endpoint effects) APOs. There are no hits for those terms in MSDN. Is this true? Is there any documentation? -- Tim Roberts, timr@xxxxxxxxx Providenza & Boekelheide, Inc. ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/ X3
