Claim:
1. An audio conference device comprising: a classification unit configured to receive audio data flows from terminal devices of audio conference participants, the classification unit configured to evaluate classification information for a first time segment provided in the audio data flows and determine a number of groups to which the audio data flows are to be assigned, the groups comprising at least a first group, a second group, and a third group, the classification unit configured such that, for each of the audio data flows, the classification unit determines which of the groups that the audio data flow is to be assigned for the first time segment such that the audio data flows assigned to the first group have a homogenous result from the evaluation of the classification information of the first time segment of the audio data flows and the audio data flows assigned to the second group have a homogenous result from the evaluation of the classification information of the first time segment of the audio data flows and the audio data flows assigned to the third group have a homogenous result from the evaluation of the classification information of the first time segment of the audio data flows; an amplification unit configured to receive amplification information from the classification unit and process the first time segment of the audio data flows such that the received audio data flows in each group are attenuated to a group specific attenuation based upon the amplification information such that the audio data flows assigned to the first group are attenuated differently than the audio data flows assigned to the second group for the first time segment and the audio data flows assigned to the second group are attenuated differently than the audio data flows assigned to the third group for the first time segment and the audio data flows assigned to the third group are attenuated differently than the audio data flows assigned to the first group for the first time segment; a mixing unit, the mixing unit configured to receive the processed received audio data flows of the first time segment by superimposing or mixing the processed received audio data flows for forming audio conference audio data flows for sending to the terminal devices; and wherein for each group, the amplification unit is configured to attenuate the audio data flows with group specific attenuation based on a number of total audio data flows within the group.
