Method and apparatus for remote capture of audio in a handheld device
Some embodiments herein include at least one of systems, methods, and devices for remote audio capture using a hand-held device. In some embodiments, the device captures, stores, and transmits audio to another device via wireless technologies. In some embodiments, the device may be used either as a hand-held microphone or as a lavaliere microphone.
1. A system comprising:
a first device that includes:
an elongated housing structure of sufficient length to fit in the palm of a human hand, the elongated housing structure with two ends;
a microphone operable to capture audio data located on one of the two ends of the elongated housing structure;
an antenna within the housing structure, operable to transmit wirelessly the captured audio data to other devices;
a clip attached to the elongated housing structure, operable to attach the housing structure to human clothing;
a processor;
a first memory coupled to the processor;
instructions stored on the first memory, operable to cause the processor to execute a wireless protocol;
a wireless application programming interface (API) executable by the processor to send and receive data;
a wireless chip coupled to the processor, the wireless chip operable to send and receive wireless signals;
a battery, which supplies power to the microphone, the antenna, the processor, the first memory, and the wireless chip;
wherein the first device is worn and used by a human as a lavaliere microphone, and wherein the first device is used as a hand-held microphone;
a second device, wherein the second device wirelessly receives a stream of the audio data from the first device, wherein the second device captures a stream of video data, and wherein there is a latency between the stream of audio data and the stream of video data;
a calculator that calculates a latency between the stream of audio data and the stream of video data;
a synchronizer that removes the latency between the audio and video data to synchronize the audio data and video data; and
a combiner that combines the synchronized audio data and video data into an audio-video file.
2. The system of claim 1 , wherein the wireless protocol is a Bluetooth® protocol.
3. The system of claim 1 , wherein the elongated housing structure has a maximum diameter of 0.5 inches.
4. The system of claim 1 , wherein the first device further includes a second memory, coupled to the processor, operable to store streams of audio data captured by the microphone.
5. The system of claim 4 , wherein the second memory is removable.
6. The system of claim 1 , wherein the battery is removable.
7. The system of claim 1 , wherein the battery is rechargeable.
8. The system of claim 1 , wherein the elongated housing structure is attachable to a stand via a tripod socket, thereby permitting hands-free use.
9. The system of claim 1 , wherein the second device is a smart phone that further includes a second processor and a third memory, wherein the second processor executes an app stored in the third memory.
10. The system of claim 1 , wherein the second device is an iPhone® that further includes a second processor and a third memory, wherein the second processor executes an app stored in the third memory.
11. The apparatus system of claim 1 , wherein the second device receives the stream of audio data from the first device via a Bluetooth® connection.
12. The system of claim 1 , wherein the second device is a smart phone that includes a second processor, a third memory, and a fourth memory, wherein the second processor executes an app stored in the third memory, wherein the fourth memory is removable, and wherein the second processor stores the audio-video file in the fourth memory.
13. The system of claim 1 , wherein the second device includes a second processor, a third memory, and a fourth memory, wherein the second processor executes an app stored in the third memory, wherein the fourth memory is removable, and wherein the second processor stores the audio-video file in the fourth memory.
14. The system of claim 1 , further comprising a recorder that records the audio-video file.
15. The system of claim 1 , wherein the first device receives input from a user and, based on the input from the user, transmits start/stop commands to the second device.
16. The system of claim 1 , wherein the second device is smart phone, and wherein the smart phone contains the calculator, the synchronizer, and the combiner.
17. The system of claim 1 , wherein the calculator, the synchronizer, and the combiner operate on an audio timeline and a video timeline based on scrub information from a user to position the audio timeline in relation to the video timeline.
18. The system of claim 1 , wherein the second device is a smart phone, and wherein the first device receives input from a user and, based on the input from the user, transmits start/stop commands to the smart phone.
19. The system of claim 1 , wherein the housing structure is attachable to a stand via a tripod socket, thereby permitting hands-free use, and wherein the elongated housing structure has a maximum diameter of 0.5 inches.
20. The system of claim 1 , wherein the first device further includes a second memory, coupled to the processor, operable to store streams of audio data captured by the microphone, and wherein the second device is a smart phone.
