Abstract

An apparatus including a recording system for recording at least sound, the recording system including a microphone; a distance input adapted to have an initial distance between a source of the sound and the apparatus entered into the apparatus; and a controller connected to the microphone. The controller is configured to determine a suggested distance for a better sound recording by the recording system based, at least partially, on the initial distance input into the distance input.

Claims

1. An apparatus comprising:

a recording system for recording at least sound, the recording system comprising at least one microphone;

a distance input configured to input an estimate of an actual distance between a source of the sound and the apparatus; and

a controller connected to the recording system and the distance input, the controller comprising a processor and a memory configured to automatically adjust gain of a sound signal from the at least one microphone to be recorded by the recording system based, at least partially, on the estimate of the actual distance between the apparatus and the source of the sound as indicated by the distance input,

where the apparatus is a hand-held portable electronic device.

2. An apparatus as in claim 1 wherein the recording system comprises a solid state memory which is configured to have the varied gain sound signal recorded thereon.

3. An apparatus as in claim 1 wherein the microphone is a variable gain cutout microphone.

4. An apparatus as in claim 2 wherein the microphone comprises a fixed gain output microphone, and the recording system comprises a variable gain amplifier connected between the microphone and the memory.

5. An apparatus as in claim 1 wherein the distance input comprises a user interface which is configured to allow a user to manually input distance information, as the estimate of the actual distance, into the apparatus.

6. An apparatus as in claim 5 wherein the user interface comprises a touch screen.

7. An apparatus as in claim 6 wherein the apparatus comprises software to allow a user to slide a finger along the touch screen to vary an indication of the estimate of the actual distance.

8. An apparatus as in claim 1 wherein the distance input comprises a distance measurement device which is configured to measure the estimate of the actual distance and automatically input the estimate into the distance input.

9. An apparatus as in claim 8 wherein the apparatus comprises a user actuator for allowing a user to selectively activate the distance measurement device.

10. An apparatus as in claim 1 wherein the microphone comprises a fixed gain output microphone, and the recording system comprises an attenuator connected between the microphone and the memory which is adapted to attenuate the sound signal from the microphone.

11. An apparatus as in claim 1 wherein the recording system is configured to record video.

12. An apparatus as claim 1 wherein the apparatus comprises a telephone with a transmitter and a receiver.

17. An apparatus as in claim 12 wherein the user interface comprises a touch screen.

18. An apparatus as in claim 17 wherein the apparatus comprises software to allow a user to slide a finger along the touch screen to vary an indication of the distance.

13. An apparatus comprising:

a recording system for recording at least sound, the recording system comprising a microphone;

a user interface configured to allow a user to input distance information into the user interface regarding an estimate of an actual distance between the apparatus and a source of the sound; and

a system comprising a processor and a memory configured to automatically control a recording level of a signal from the microphone based, at least partially, upon the distance information which is input by the user at the user interface,

where the apparatus is a hand-held portable electronic device.

14. An apparatus as in claim 13 wherein the recording system comprises a solid state memory which is configured to have the sound recorded thereon.

15. An apparatus as in claim 13 wherein the microphone is a variable gain output microphone.

16. An apparatus as in claim 14 wherein the microphone comprises a fixed gain output microphone, and the recording system comprises a variable gain amplifier connected between the microphone and the memory.

19. An apparatus as in claim 13 wherein the recording system is configured to record video.

20. An apparatus as in claim 13 wherein the apparatus comprises a telephone with a transmitter and a receiver.

21. A method comprising:

inputting into an apparatus distance information regarding a distance between the apparatus and a source of sound;

increasing or decreasing an output signal from a microphone of the apparatus automatically by a system comprising a processor and a memory based, at least partially, upon the distance information input into the apparatus, the microphone being a sole microphone of the apparatus; and

recording the increased or decreased output signal on a recording medium by the apparatus,

where the apparatus is a hand-held portable electronic device comprising a telephone with a transmitter and a receiver.

22. A non-transitory program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine for performing operations, the operations comprising:

upon receiving by an apparatus input comprising distance information regarding a distance between the apparatus and a source of sound, automatically increasing or decreasing an output signal from a microphone of the apparatus based, at least partially, upon the distance information, the microphone being a sole microphone of the apparatus; and

recording the increased or decreased output signal on a recording medium by the apparatus,

where the apparatus is a hand-held portable electronic device comprising a telephone with a transmitter and a receiver.
