![]() Sets the default properties for the endpoint. For more information about KSNODETYPE_SPEAKER and other pin-category GUIDS, see Ksmedia.h in WinDDK\\inc\api. For example, when the AudioEndpointBuilder finds an unconnected bridge pin with a pin-category GUID of KSNODETYPE_SPEAKER, it creates a speaker endpoint for this bridge pin. ![]() The following list summarizes how the algorithm that is used by AudioEndpointBuilder works:Ĭreates an endpoint for any unconnected bridge pins. When an audio device driver registers a new instance of the KSCATEGORY_AUDIO device interface class, the AudioEndpointBuilder service detects the device interface notification and uses an algorithm to examine the topology of the audio devices in the system and take appropriate action. The AudioEndpointBuilder service monitors the KSCATEGORY_AUDIO class for device interface arrivals and removals. The MMDevice API refers to the new audio devices as endpoints. With two new APIs in Windows Vista, MMDevice API and WASAPI, you can access and manipulate these new audio devices. In Windows Vista and later versions of Windows, the concept of an audio device has been redesigned to better represent the device that the user physically interacts with. In Windows XP, the audio model used the term audio device to refer to a conceptual device in the Plug and Play (PnP) tree. The algorithm was designed to simplify the system access to multiplexed (MUXed) capture devices and to help work with topologies that involve multiple host pins and multiple bridge pins, or both. The AudioEndpointBuilder service uses an algorithm to discover and enumerate endpoints. This topic provides an overview of the algorithm that is used by the AudioEndpointBuilder service. The user can also query the audio properties of input files.Īt the end of the audiobook build process, the user can choose to have the audiobook automatically added to their iTunes Library.In Windows Vista and later versions of Windows, the AudioEndpointBuilder is a system service that enumerates, initializes, and activates the audio endpoints in a system. Additional tools are provided to import/export metadata, artwork and chapters. ![]() Project files containing all input file, chapter and metadata settings can be saved and opened to allow for later editing. The user can then add a chapter at specific time or adjust an existing chapter in the audiobook based on the time position of the player during playback. Title, Artist, Album, Composer and Comment tags) as well as the cover artwork for the combined audiobook.Ī virtual copy of the audiobook is created to allow the user to test the changes and to be able to listen to the audiobook prior to building the combined audiobook. The user can specify fourteen (14) metadata or information tags (e.g. ![]() Chapter images can also be specified for the chapters and they will be shown during playback on iTunes, QuickTime and on selected iPods. If a single file with existing chapters is selected, the user can then add to, modify or delete the existing chapters. Chapters can be created automatically at the start of each input file and they can also be added at regular intervals specified by the user. Non-AAC files are automatically converted using iTunes.Ĭhapters can be added, modified or deleted as desired for the combined audiobook. Starting with Advanced Audio Coding (AAC) formatted files, or any other audio file supported in iTunes, the user can combine multiple input files into a single audiobook file with chapter marks. Chapter and Verse is a free software tool to create chapterized audiobooks for the iPod, iTunes, and Quicktime.
