Abstract
A distributed recording system includes a first device and one or more second devices. The first device sends a distributed recording instruction, to control the one or more second devices to perform recording. The one or more second devices send audio data obtained through recording to an upper-layer recording application.
Claims20
A recording system, comprising:
- a first device configured to:
- receive input information of a user;
- and
- send a distributed recording start instruction when a recording mode corresponding to the input information is a distributed recording mode;
- and
- a second device configured to:
- receive, from the first device, the distributed recording start instruction;
- collect, according to the distributed recording start instruction, first audio data in a first periodicity, wherein the first audio data is first local audio data collected by the second device;
- perform human voice enhancement or noise reduction processing on the first audio data in a second periodicity to produce second audio data;
- and
- send the second audio data to the first device in the second periodicity to instruct the first device to invoke at least one piece of the second audio data with a camera application.
8 more elements
A first device, comprising:
- a memory configured to store instructions;
- and
- one or more processors coupled to the memory and configured to execute the instructions to:
- receive input information of a user;
- send, to a second device, a distributed recording start instruction when a recording mode corresponding to the input information is a distributed recording mode;
- receive, from the second device, first audio data;
- invoke, by a camera application, at least one piece of the first audio data;
- perform a time alignment operation on a plurality of pieces of the first audio data when the first audio data comprises the plurality of pieces;
- and
- perform the time alignment operation on the first audio data and second audio data collected by the first device when the recording mode is a multi-device collaborative recording mode.
