identifying a mobile device identification characteristic of the mobile device based on the received audio data signal; identifying a microphone nearest a location where the mobile device is located based on the audio data signal being received from the mobile device at the nearest microphone; determining a location of the mobile device based on the location of the nearest microphone; and playing the audio signal via a loudspeaker. ### Claim 2 (depends on 1) The method of claim 1, comprising: mixing the audio signal with a watermark audio signal. ### Claim 3 (depends on 1) The method of claim 1, comprising: responsive to identifying the mobile device location, capturing a photograph of the location of the mobile device to identify a participant associated with the mobile device; and forwarding the photograph to participating mobile devices when playing the audio signal via the loudspeaker. ### Claim 4 (depends on 1) The method of claim 1, wherein the received audio data signal comprises one or more of textual data, audio data, image data and video data. ### Claim 5 (depends on 2) The method of claim 2, wherein the watermark audio signal comprises identification information associated with the one or more mobile devices, location information of the one or more mobile devices and data subtraction information regarding information to subtract from the audio signal. ### Claim 6 (depends on 1) The method of claim 1, comprising: displaying the audio data on a display associated with a presenter device in communication with the presentation server. ### Claim 7 An apparatus comprising: a receiver configured to receive, at a presentation server, an audio data signal from a mobile device located in a presentation space; and a processor configured to identify a mobile device identification characteristic of the mobile device based on the received audio data signal; identify a microphone nearest a location where the mobile device is located based on the audio data signal being received from the mobile device at the nearest microphone; determine a location of the mobile device based on the location of the nearest microphone; and play the audio signal via a loudspeaker. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the processor is further configured to: mix the audio signal with a watermark audio signal. ### Claim 9 (depends on 7) The apparatus of claim 7, wherein responsive to the mobile device location being identified, the processor is configured to capture a photograph of the location of the mobile device to identify a participant associated with the mobile device, and forward the photograph to participating mobile devices when playing the audio signal via the loudspeaker. ### Claim 10 (depends on 7) The apparatus of claim 7, wherein the received audio data signal comprises one or more of textual data, audio data, image data and video data. ### Claim 11 (depends on 8) The apparatus of claim 8, wherein the watermark audio signal comprises identification information associated with the one or more mobile devices, location information of the one or more mobile devices and data subtraction information regarding information to subtract from the audio signal. ### Claim 12 (depends on 7) The apparatus of claim 7, wherein the processor is further configured to display the audio data on a display associated with a presenter device in communication with the presentation server. ### Claim 13 A non-transitory computer readable storage medium configured to store instructions that when executed cause a processor to perform: receiving, at a presentation server, an audio data signal from a mobile device located in a presentation space; identifying a mobile device identification characteristic of the mobile device based on the received audio data signal; identifying a microphone nearest a location where the mobile device is located based on the audio data signal being received from the mobile device at the nearest microphone; determining a location of the mobile device based on the location of the nearest microphone; and playing the audio signal via a loudspeaker. ### Claim 14 (depends on 13) The non-transitory computer readable storage medium of claim 13, wherein the processor is further configured to perform: mixing the audio signal with a watermark audio signal. ### Claim 15 (depends on 13) The non-transitory computer readable storage medium of claim 13, wherein the processor is further configured to perform: responsive to identifying the mobile device location, capturing a photograph of the location of the mobile device to identify a participant associated with the mobile device; and forwarding the photograph to participating mobile devices when playing the audio signal via the loudspeaker. ### Claim 16 (depends on 13) The non-transitory computer readable storage medium of claim 13, wherein the received audio data signal comprises one or more of textual data, audio data, image data and video data. ### Claim 17 (depends on 14) The non-transitory computer readable storage medium of claim 14, wherein the watermark audio signal comprises identification information associated with the one or more mobile devices, location information of the one or more mobile devices and data subtraction information regarding information to subtract from the audio signal. ### Claim 18 (depends on 13) The non-transitory computer readable storage medium of claim 13, wherein the processor is further configured to perform displaying the audio data on a display associated with a presenter device in communication with the presentation server.
