Abstract: Conference systems are used for example in discussions and usually comprise a plurality of delegate units with microphones, whereby in a discussion each discussion participant uses his own delegate unit. Usually the delegate units have a switch or the like, that allows the participant in front of the delegate unit to request, that his microphone is activated, so that the speech of the participant is input in the conference system and amplified by the conference system. A conference system comprising (1) a plurality of delegate units (2), each delegate unit (2) having a microphone (5) for receiving an audio signal from a surrounding, a central service module (3) handling a plurality of contribution channels, whereby the audio output of the contribution channels contribute to an amplified audio output of the conference system (1) is proposed, whereby each delegate unit (2) is adapted to send a request for a contribution channel commit to the central service module (3), whereby the central service module (2) is adapted to grant the request and to allocate a contribution channel to the requesting delegate unit (2), thus setting the requesting delegate unit i in an active state A, whereby the delegate unit (2) is adapted to trigger the request by voice activation, whereby the request is triggered in case at least a first trigger condition is fulfilled defining that the audio signal level of one of the delegate units (2) as a possible requesting delegate unit i is higher than an individual test value for each other delegate unit (2) in the active state A, whereby the individual test value is an estimated audio signal level of the possible requesting unit i resulting from an audio or speech signal provided to the other active delegate units (2).

Abstract: Recording devices are often used to record discussions, conferences, meetings and the like. The recorded information is reviewed or processed afterwards for example in order to prepare minutes or notes. The known state of the art proposes to use devices comprising two receptacles for tapes. But this solution adds cost to the recording devices, which will not be accepted from all potential buyers as only a small number of the buyers will actually use this functionality. A recording apparatus (1) for recording of audio signals is proposed comprising an external interface (6) for an exchangeable storage medium (7) and an intermediate memory device (5), whereby the recording apparatus (1) is realised to use the intermediate memory device (5) and the storage medium (7) for storing the audio signals, whereby the recording apparatus (1) is realised for an interruption-free storage of the audio-signals during a storage medium (7) exchange, wherein a first storage medium is exchanged by a second storage medium, whereby during the storage medium (7) exchange the audio signals are stored on the intermediate memory device (5) and whereby the audio signals stored on the intermediate memory device (5) are transferred to the second storage medium.
