Problems solved by technology

[0004] In view of this, the embodiments of the present invention provide a sound processing method, device, terminal and computer-readable storage medium to solve the problem of the need for a directional microphone to pick up sound due to the limited range of the directional microphone in the prior art. Manually arrange the position of the microphone according to the venue, the operation is inconvenient, and when the omnidirectional microphone is used to pick up sound, the omnidirectional microphone cannot effectively distinguish the effective sound source from the noise source, and the sound signals from the effective sound source and the noise source are analyzed. Indiscriminate sound pickup, resulting in poor quality of the sound signal from the collected effective sound source

Embodiment 1

[0032] This embodiment provides a sound processing method, which can be applied to various sound processing terminals, wherein the sound processing terminal includes a microphone, and the microphone includes multiple microphones, such as Figure 1A Shown is a schematic diagram of a sound processing terminal, such as Figure 1B As shown, the processing of the sound by the sound processing terminal includes the following steps:

[0033] S10: Obtain a plurality of first sound signals and a plurality of second sound signals collected by a plurality of microphone heads; wherein, the plurality of first sound signals are generated by the first sound source, and the plurality of second sound signals are generated by the second sound source source generated.

[0034] Such as Figure 1C As shown, the digital microphone transmits the collected audio data to the conference terminal through the audio playback interface. The first sound source is the on-site participants of the video conf...

Embodiment 2

[0061] This embodiment provides a sound processing device, such as figure 2 As shown, the digital microphone transmits the collected audio data to the conference terminal through the audio playback interface, specifically including: an acquisition module 10 , a determination module 20 , a distribution module 30 , and a processing module 40 .

[0062] The acquiring module 10 is configured to acquire a plurality of first sound signals and a plurality of second sound signals collected by a plurality of microphone heads; wherein, the plurality of first sound signals are generated by a first sound source, and the plurality of the second sound signal is generated by a second sound source;

[0063] A determining module 20, configured to determine the relative positions of the first sound source and the plurality of microphones and the relative positions of the second sound source and the plurality of microphones;

[0064] Further, as a preferred implementation manner of this embodi...

Abstract

The invention discloses a sound processing method and apparatus, a terminal and a computer readable storage medium. The method comprises the following steps: obtaining a plurality of first sound signals and a plurality of second sound signals collected by a plurality of microphones, wherein the first sound signals are generated by a first sound source, and the second sound signals are generated by a second sound source; determining relative positions of the first sound source and the plurality of microphones, and the relative positions of the second sound source and the plurality of microphones; separately allocating a first group of weights to the plurality of first sound signals obtained from the plurality of microphones, and allocating a second group of weights to the plurality of second sound signals obtained from the plurality of microphones; and performing sound mixing processing on the plurality of first sound signals and the plurality of second sound signals by using the first group of weights and the second group of weights. By adoption of the sound processing method and apparatus, a collection direction can be automatically selected for the sound mixing processing, and more effective sound signals can be collected.

Description

technical field [0001] The present invention relates to the field of audio analysis and processing, in particular to a sound processing method, device, terminal and computer-readable storage medium. Background technique [0002] In video conferencing scenarios, directional or omnidirectional microphones are generally used for sound collection. The range of sound pickup by directional microphones is limited, so multiple directional microphones are required to collect sound at the same time to meet the extended sound pickup range, that is, multiple independent directional microphones are used to collect audio to the same conference terminal device, and the audio is tuned Centralized audio mixing at stations or conference terminals. This method requires manual placement of microphones according to the venue, and the need to manually switch the mute key when speaking. It is very inconvenient to use and the experience is relatively poor. [0003] The omnidirectional microphone c...
