Problems solved by technology

[0004] The single-audio collection device cannot distinguish between two channels and cannot perform noise reduction; the main and secondary audio collection devices in the dual-audio collection device have been designated. When the user is far away from the main audio collection device and the secondary audio collection device is close when recording It will cause only the background sound to be recorded, while the user's voice is removed as noise, the noise reduction effect is poor, the judgment of the main signal is inaccurate, and the recording clarity is low

Embodiment 1

[0047] figure 1 It is a schematic flow chart of a recording method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of recording, and the method can be executed by a recording device. Such as figure 1 As shown, the method specifically includes the following steps:

[0048] S110. Acquire the collected first sound signal, and determine the first sound signal as a main sound source according to a preset standard.

[0049]Wherein, the first sound signal is sent by the user or other sound-emitting devices, and the first sound signal can be used to wake up the recording function of the device. The computer device acquires the first sound signal collected by any audio collection device, wherein the computer device may be a terminal device such as a mobile phone, a computer, or a smart watch, and the audio collection device may be a device such as a microphone. Comparing the first sound signal with the voice command preset by the user to ...

Embodiment 2

[0065] figure 2 It is a schematic flowchart of a recording method provided by Embodiment 2 of the present invention. This embodiment is further optimized on the basis of the foregoing embodiments, and the method can be executed by a recording device. Such as figure 2 As shown, the method specifically includes the following steps:

[0066] S210. Acquire the collected first sound signal, and determine the first sound signal as the main sound source according to a preset standard.

[0067] Wherein, the voice wake-up command is preset, and if the content of the first sound signal acquired by the computer device matches the content of the voice wake-up command, the recording function is turned on, and the first sound signal is the main sound source. The main sound source provides the judgment standard for the sound to be recorded in the subsequent recording process.

[0068] S220. Compare the spectrum of the second sound signal collected by any one of the at least two audio co...

Embodiment 3

[0094] Figure 5 It is a structural block diagram of a recording device provided in Embodiment 3 of the present invention, which can execute the recording method provided in any embodiment of the present invention, and has corresponding functional modules and beneficial effects for executing the method. Such as Figure 5 As shown, the device specifically includes:

[0095] The main sound source determining module 501 is configured to acquire the collected first sound signal, and determine the first sound signal as the main sound source according to a preset standard.

[0096] The main signal determination module 502 is configured to compare the spectrum of the second sound signal collected by any one of the at least two audio collection devices with the main sound source, and determine the main signal and auxiliary signal in the second sound signal.

[0097] The audio collection device determination module 503 is used to determine the main audio collection device and the sec...

Abstract

The embodiment of the invention discloses a recording method, device, equipment and storage medium. Wherein, the method is performed by including at least two audio collection devices, including: acquiring the collected first sound signal, and determining the first sound signal as the main sound source according to a preset standard; each of the at least two audio collection devices The second sound signal collected by the audio collection device is compared with the main sound source to determine the main signal in the second sound signal; according to the sound parameters of the main signal in the second sound signal in each audio collection device, determine at least two The main audio collection device and the secondary audio collection device in the two audio collection devices use the main audio collection device for sound recording, and use the secondary audio collection device for noise reduction processing. By determining the main sound source, comparing the voice with the main sound source to obtain the main signal, and determining the main-sub-relationship of the audio collection equipment, it will play a corresponding role and improve the accuracy of the judgment of the main signal and the clarity of the recording.

Description

technical field [0001] Embodiments of the present invention relate to signal processing technologies, and in particular, to a recording method, device, equipment, and storage medium. Background technique [0002] As an essential function of contemporary mobile terminals, audio and video recording is gradually known by consumers. However, in the process of recording and video recording, there is usually a lot of noise, which cannot deliver clear sound. [0003] At present, for the recording and video recording function of the mobile terminal, a single audio collection device or a dual audio collection device is usually used for recording. A single-audio acquisition device has a single channel when recording, and records voice and background sound at the same time; although a dual-audio acquisition device can perform noise reduction during recording, the main and auxiliary audio acquisition devices have been designated before recording, and the designated main audio The coll...
