+\section misc_connfor Connection Formats
+Every flow of audio is using a format to exchange data. 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:

+\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.
