Embodiment Construction

[0028] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0029]Due to the current emergency broadcasting system, there are many kinds of broadcasting sound sources and broadcasting audio equipment. Different sound sources enter different broadcasting audio equipment, and the output gain is also different. Such audio is sent to the broadcasting terminal through different transmission channels. , The volume of sound output by the broadcast terminal after decoding is inconsistent. If the sound is too small, the user cannot hear clearly, which will bring a very poor experience to the user. If the sound is too loud, it is easy to cause the amplifier to burn out. Therefore, in order to avoid this impact, the current solution must match various broadcast audio equipment and broadcast terminals in the early stage of project implementation, but this method takes a ...

Abstract

The invention provides an audio gain control method and device, a broadcast terminal and a storage medium. The method comprises the following steps: receiving audio data sent by broadcast audio equipment; decoding the audio data to generate pulse code modulation data; adjusting the audio gain of the pulse code modulation data according to the difference between the audio gain of the pulse code modulation data and a preset gain, and generating target pulse code modulation data meeting a preset condition; and outputting the target pulse code modulation data. Compared with the prior art, the broadcast audio device and the broadcast terminal do not need to be matched in advance, and manpower and material resources are saved. Moreover, the received audio data is adjusted, so that the audio finally output by the broadcast terminal meets the expectation, and the power amplifier is ensured to be in a stable state.

Description

technical field [0001] The present application relates to the technical field of broadcast audio, and in particular, to an audio gain control method and device, a broadcast terminal and a storage medium. Background technique [0002] In the existing emergency broadcasting system, there are many kinds of broadcasting sound sources and broadcasting audio equipment. Different sound sources enter different broadcasting audio equipment, and the output gain is also different. Such audio is sent to the broadcasting terminal through different transmission channels. , The volume of sound output by the broadcast terminal after decoding is inconsistent. If the sound is too small, the user cannot hear clearly, which will bring a very poor experience to the user. If the sound is too loud, it is easy to cause the amplifier to burn out. Therefore, in order to avoid this impact, the current solution must match various broadcast audio equipment and broadcast terminals in the early stage of p...
