A method for controlling a wireless multi-channel audio system (100) is provided, wherein the system (100) has at least two mobile devices (300), each for transmitting and/or receiving audio data in the form of at least one audio stream, and at least one base station (400), wherein the mobile devices (300) and the base station (400) exchange audio data wirelessly in a Time Division Multiplex Access TDMA method, wherein this wireless transmission takes place on the basis of repeating frames (SF), wherein each frame (SF) has a number (A) of time slots (SL), wherein each mobile device (300) transmits or receives audio data of an audio stream in at least one time slot (SL) at least once per frame (SF), wherein each audio stream transmitted in the frame (SF) occupies a proportion (T) of the time slots (SL) of the frame (SF), wherein the base station (400) transmits control data (201) to the mobile devices (300) for controlling the wireless transmission. The method comprises the following steps: In response to a user input to add further audio data of at least one further audio stream: searching for at least one time slot (SL) in the frame (SF) which is not occupied by an audio stream with a larger or equal proportion (T) of the time slots (SL), placing a new audio stream in the at least one time slot (SL) which has been found, recording all the already existing audio streams displaced thereby, searching for at least one further time slot (SL) in the frame (SF) for a next or a displaced audio stream which is not occupied by an audio stream with a larger or equal proportion (T) of the time slots (SL), placing a new or displaced audio stream in the further time slot (SL) which has been found, and repeating the steps of searching and placing until all the audio streams have been accommodated in the time slots. Each audio stream is distributed substantially isochronously in the time slots of the frames.
