The format that the source and the sink uses must match together in order to have an undisturbed +experience. It is common that sources and sinks are capable of supporting more than one audioformat.\n +So all sources and sinks register with a list of connectionFormats that they support and for each connection a format must be chosen that is then used +to transport the audio data. Gateways (and Soundconverters) have the information which connectionFormat can be transformed into another one. +am::am_CustomAvailabilityReason_t has all formats listed.\n +There is a special usecase that is worth showing as an example in this regard: the change of a connectionFormat when switching from one song to another. Here is an +example of how the project specific parts could handle this: +\image html ChangeofAudioformatduringplaytime.png + + +\section misc_pers Persistence +The persistence client library is defined as an abstract component with a c-like library interface. Since the AudioManagerController is the only one to know +what is to be made persistent, he is the one interfacing with that library. This is the reason why there is no specific interface for the persistence here. + +\section misc_speed Speed dependent volume +The adjustments for the speed are done product specific in the controller. The speed information itself is retrieved by the AudioManagerDaemon, sampled and +quantified and forwarded to the controller. The interface in not yet defined !\n +Turning speed controlled volume on/off and possible settings are achieved via SinkSoundProperty settings. +*/
