The invention relates to the technical field of acoustics, in particular to a pickup state regulation and control method and system for a variable directional pickup, and the method comprises the steps: confirming a pickup test unit, and carrying out the directional coordinate test of a pre-constructed test pickup through the pickup test unit, and determining a target heart-shaped space and a target bidirectional space in a target space coordinate system based on the heart-shaped coordinate set and the bidirectional coordinate set, performing real-time pickup on a target sound source in the sound regulation and control environment by using the started variable directional pickup, and performing sound source positioning operation on the target sound source by using the quaternary cross microphone array. And performing mode correction operation on the variable directional pickup based on the target sound source point, the target heart-shaped space and the target bidirectional space to obtain a target pickup, and obtaining a target recording file until a preset pickup end instruction is received, thereby completing pickup state regulation and control of the pickup. According to the invention, the automatic regulation and control of the pickup mode in the variable directional pickup can be realized, and the recording tone quality of the variable directional pickup is improved.

The invention provides sound recording equipment, a sound recording method, a storage medium and a product. The sound recording equipment comprises a controller, a first microphone module and a first sound recording acquisition module, the first recording acquisition module comprises at least two gain channels with different gain values; the first microphone module collects an audio signal and transmits the audio signal to each gain channel for analog gain; the first recording acquisition module performs analog-to-digital conversion on the analog gain signals output by the gain channels to obtain digital signals corresponding to the gain channels, and transmits the digital signals corresponding to the gain channels to the controller; and the controller determines a target gain channel corresponding to the audio signal according to the signal strength of the digital signal corresponding to each gain channel, takes the digital signal corresponding to the target gain channel as a recording signal corresponding to the audio signal, and stores the recording signal. According to the scheme, appropriate gains are selected according to the audio signals with different intensities, so that the recording quality during wide dynamic range recording is improved.

The invention relates to a recording method, first equipment, second equipment and a storage medium. A second device can receive a first message sent by a first device; determining target noise reduction parameters corresponding to audio acquisition devices on the second equipment according to the first message, wherein the second equipment is provided with at least two audio acquisition devices; and recording an audio emitted by a sound source according to the target noise reduction parameter corresponding to the audio acquisition device.

The invention is suitable for the technical field of earphones, and provides an earphone recording method and device, earphone equipment and a readable storage medium. The earphone recording method comprises the following steps: receiving an audio signal sent by a mobile terminal; detecting the audio signal; when it is detected that the audio signal is call audio and a recording instruction is received, recording the call audio, and performing real-time recording processing in the recording process to obtain a recording file; and storing the recording file. According to the embodiment of the invention, recording can be realized through the earphone equipment, recording software is not needed for recording, and the method is suitable for various types of mobile terminals. In addition, real-time recording processing is carried out in the recording process, and the recording quality can be effectively improved.

This utility model relates to the field of pet equipment technology, specifically to a pet activity monitoring collar with a removable battery. Under normal circumstances, when the accelerometer detects that the collar is stationary and has been placed there for 10 minutes, the accelerometer will promptly transmit this detected state signal to the main control MCU. Upon receiving the signal, the main control MCU will immediately enter sleep mode, thereby reducing energy consumption and achieving energy saving. However, once the accelerometer senses that the collar has moved, it will immediately receive this dynamic change signal and quickly transmit the signal to the main control MCU, thereby controlling the main control MCU to start from sleep mode. After the main control MCU is awakened, it will activate the audio IC through its control function. When the audio IC is activated, it will output an analog signal to the speaker device, ultimately enabling the stored voice commands to be played clearly and accurately for further operation or command transmission.

The embodiment of the invention provides a method and a system for recording a double-stream video conference, which are applied to a first server, and the method comprises the following steps: obtaining audio and video stream data to be recorded; analyzing first video stream data and second video stream data from the audio and video stream data; the first video stream data and the second video stream data are recorded respectively to obtain a first video file and a second video file, respective processing identification information is added, and the processing identification information is used for identifying and distinguishing different video files; and storing the first video file, the second video file and the processing identification information corresponding to the first video file and the second video file in a database. The embodiment of the invention supports effective file management and retrieval functions. The problems that multiple paths of video streams cannot be recorded at the same time and main and auxiliary streams are asynchronous in the prior art are solved, and the recording efficiency and the information integrity are improved.
