Abstract

An apparatus and method for autonomously mixing multiple devices capable of storing and playing audio signals is provided. Multiple devices can be mixed into one standard stereo signal that can then be played on any sort of powered speakers or amplifier. The apparatus is capable of receiving multiple audio inputs and can combine multiple iPods®, iPhones®, MP3 devices, or other devices capable of storing and playing audio signals, such that more than one device can be played at one time. No human intervention is required to control the device when the device is in autonomous mode. The autonomous mode can include random song playback using multiple devices.

Claims

1. An apparatus for signal mixing, comprising:

a signal mixing circuit capable of receiving a plurality of input signals and outputting at least one output signal, wherein the at least one output signal comprises a mixing of the plurality of input signals;

a plurality of receiving ports, each receiving port capable of receiving a device capable of storing a plurality of signal files and outputting a signal, wherein the signal is at least a portion of one of the plurality of signal files stored on the received device, wherein the received devices provide the plurality of input signals directed to the signal mixing circuit;

a controller capable of sending a first command signal to one or more of the received devices to cause the one or more of the received devices to output a corresponding one or more of the plurality of input signals.

2. The apparatus according to claim 1, wherein the plurality of signal files is a plurality of audio signal files.

3. The apparatus according to claim 1, wherein the plurality of signal files is a plurality of video signal files.

4. The apparatus according to claim 1, wherein the received devices are portable devices.

5. The apparatus according to claim 1, further comprising:

a power system capable of providing power to one or more of the received devices.

6. The apparatus according to claim 1, wherein the apparatus is capable of receiving power from at least one of the received devices.

7. The apparatus according to claim 1, wherein the at least one output signal is a single output signal.

8. The apparatus according to claim 1, wherein at least one of the plurality of receiving ports is wireless.

9. The apparatus according to claim 1, further comprising:

a user interface;

wherein the controller is further capable of communicating with the user interface.

10. The apparatus according to claim 9, wherein the controller creates a library that incorporates information with respect to signal files from at least two of the received devices.

11. The apparatus according to claim 10, wherein the library incorporates information with respect to the signal files from all of the received devices.

12. The apparatus according to claim 9, wherein the user interface comprises a jog wheel, wherein action of the jog wheel causes a control signal to be sent to the controller.

13. The apparatus according to claim 9, wherein the user interface comprises a display screen.

14. The apparatus according to claim 13, wherein the display screen is capable of displaying information with respect to the signal files from the received devices.

15. The apparatus according to claim 1, wherein the apparatus is capable of providing autonomous mixing of the plurality of input signals.

16. The apparatus according to claim 15, wherein the controller is capable of selecting a received device, selecting a signal file from the selected received device, and causing the signal mixing circuit to output the selected signal file as the at least one output signal.

17. The apparatus according to claim 16, wherein the controller is capable of operating in a random-random mode, wherein the random-random mode comprises random received device selection and random signal track selection from the randomly selected received device.

18. The apparatus according to claim 16, wherein the controller is capable of operating in a semi-random mode, wherein the semi-random mode comprises random received device selection and pre-defined signal file selection from the randomly selected received device, wherein the pre-defined signal file selection includes a user defined setting for the received device.

19. The apparatus according to claim 16, wherein the controller is capable of operating in a random-less mode, wherein the random-less mode comprises predetermined received device selection order and pre-defined signal file selection from the selected received device, wherein the pre-defined signal file selection includes a user defined setting for the received device.

20. The apparatus according to claim 1, wherein at least one receiving port is capable of receiving an iPod®

.

21. The apparatus according to claim 1, wherein the controller is capable of sending a second command signal to the one or more of the received devices to cause the one or more received devices to provide the controller with an information signal that provides information regarding the plurality of signal files.

22. The apparatus according to claim 1, wherein the controller is capable of controlling the signal making circuit in order to control the at least one output signal.

23. The apparatus according to claim 1, wherein the received devices are hot pluggable with respect to the receiving ports.

24. The apparatus according to claim 2, further comprising a means for producing sound, wherein the means for producing sound receives the at least one output audio signal and produces sound corresponding to the at least one audio signal.

25. The apparatus according to claim 3, further comprising a means for producing video, wherein the means for producing video receives the at least one output video signal and produces video corresponding to the at least one audio signal.

26. A method for signal mixing, comprising:

providing a signal mixing circuit capable of receiving a plurality of input signals and outputting at least one output signal, wherein the at least one output signal comprises a mixing of the plurality of input signals;

providing a plurality of receiving ports, each receiving port capable of receiving a device capable of storing a plurality of signal files and outputting a signal, wherein the signal is at least a portion of one of the plurality of signal files stored on the received device, wherein the received devices provide the plurality of input signals directed to the signal mixing circuit;

providing a controller capable of sending a first command signal to one or more of the received devices to cause the one or more of the received devices to output a corresponding one or more of the plurality of input signals;

receiving at least two devices at a corresponding at least two of the plurality of receiving ports;

sending a first command signal from the controller to one or more of the least two receiving devices to cause the at least two devices to output a corresponding at least two input signals;

receiving the at least two input signals at the signal mixing circuit and outputting at least one output signal from the signal mixing circuit, wherein the at least one output signal comprises a mixing of the at least two input signals.

27. The method according to claim 26, wherein the plurality of signal files is a plurality of audio signal files.

28. The method according to claim 26, wherein the plurality of signal files is a plurality of video signal files.
