Centrally controlling communication at a venue

1. A method comprising:

receiving a data set comprising recorded audio from one or more mobile devices;

combining the received data set with additional audio data recorded from a different device to create a combined data set;

subtracting a portion of the recorded audio from the combined data set to create a modified presentation signal, wherein the subtracted portion of the one or more of the data set and the additional data comprises audio output of a loudspeaker recorded during a recording of the received data set; and

playing the modified presentation signal via the loudspeaker.

2. The method of claim 1 , wherein the received data set further comprises one or more of textual data, image data and video data.

3. The method of claim 1 , wherein the subtracted portion of the one or more of the data set and the additional data further comprises audio output associated with audience members of the presentation near the mobile device which recorded the data set.

4. The method of claim 1 , comprising

adding a watermark signal to the data set prior to forwarding the data set from the one or more mobile devices.

5. The method of claim 4 , wherein the watermark 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 a presentation signal based on the combined data set.

6. The method of claim 1 , displaying the data set on a display associated with a presenter device in communication with a presentation server.

7. The method of claim 1 , delaying the playing of the modified presentation signal via the loudspeaker for a predefined period of time.

8. An apparatus comprising:

a receiver configured to receive a data set comprising recorded audio from one or more mobile devices space;

a processor configured to

combine the received data set with additional audio data recorded from a different device to create a combined data set;

subtract a portion of the recorded audio from the combined data set to create a modified presentation signal, wherein the subtracted portion of the one or more of the data set and the additional data comprises audio output of a loudspeaker recorded during a recording of the received data set; and

play the modified presentation signal via the loudspeaker.

9. The apparatus of claim 8 , wherein the received data set further comprises one or more of textual data, image data and video data.

10. The apparatus of claim 8 , wherein the subtracted portion of the one or more of the data set and the additional data further comprises audio output associated with audience members of the presentation near the mobile device which recorded the data set.

11. The apparatus of claim 8 , wherein the processor is further configured to

add a watermark signal to the data set prior to forwarding the data set from the one or more mobile devices.

12. The apparatus of claim 11 , wherein the watermark 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 a presentation signal based on the combined data set.

13. The apparatus of claim 8 , wherein the processor is further configured to display the data set on a display associated with a presenter device in communication with a presentation server.

14. The apparatus of claim 8 , wherein the processor is further configured to delay the playing of the modified presentation signal via the loudspeaker for a predefined period of time.

15. A non-transitory computer readable storage medium configured to store instructions that when executed cause a processor to perform:

receiving a data set comprising recorded audio from one or more mobile devices;

combining the received data set with additional audio data recorded from a different device to create a combined data set;

subtracting a portion of the recorded audio from the combined data set to create a modified presentation signal, wherein the subtracted portion of the one or more of the data set and the additional data comprises audio output of a loudspeaker recorded during a recording of the received data set; and

playing the modified presentation signal via the loudspeaker.

16. The non-transitory computer readable storage medium of claim 15 , wherein the received data set further comprises one or more of textual data, image data and video data.

17. The non-transitory computer readable storage medium of claim 15 , wherein the subtracted portion of the one or more of the data set and the additional data further comprises audio output associated with audience members of the presentation near the mobile device which recorded the data set.

18. The non-transitory computer readable storage medium of claim 15 , wherein the processor is further configured to perform:

adding a watermark signal to the data set prior to forwarding the data set from the one or more mobile devices.

19. The non-transitory computer readable storage medium of claim 18 , wherein the watermark 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 a presentation signal based on the combined data set.

20. The non-transitory computer readable storage medium of claim 15 , wherein the processor is further configured to perform:

displaying the data set on a display associated with a presenter device in communication with a presentation server.
