Hello, VB-CABLE can be used as Virtual I/O by stand alone application: See AudioDensityDemo to test this technology. If you would like to implement the same in your stand alone application I propose fixed price license for specific VB-CABLE and direct access from your application. To get more information, I invite you to contact me directly Regards Vincent Burel www.vb-cable.com De : wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] De la part de Don Gateley Envoyé : mardi 7 mai 2013 23:48 À : wdmaudiodev@xxxxxxxxxxxxx Objet : [wdmaudiodev] Naive beginner with only a concept: front filter to use a VST plugin. I am here not because I am doing any development or because I have any knowledge as yet of the subject but just to toss out an idea and see what those who do have the knowledge think about its feasibility. If that is committing an act of poor etiquette here I apologize in advance. I would like a WDM front filter that is configurable to the extent of: 1) naming the path to my VST plugins directory, 2) naming a single VST plugin to insert as a filter, 3) naming a real audio device to receive the output and 4) specifying parameters to the VST plugin and opening it's GUI. In my first usage it would name and utilize the PlogueBiduleVST plugin which is an entire framework for building up more complex flows and processes. I don't really know what I am talking about here but I would hope that by pointing the "Windows Sound" panel selection to this front filter (which I hope would appear as a named output device similar to what Virtual Audio Cable provides) I would then be able to configure it with the parameters I described above via the "Properties" panel for that front end pseudo device. I am successfully doing this now via the Virtual Audio Cable and VSTHost applications but would like to considerably simplify the mechanism for use by others with a wish to filter Windows audio in a general and flexible way. Any feedback anyone would care to provide as to the feasibility and the difficulty would be greatly appreciated. Thanks, Don Gateley
