The embodiment of the invention discloses a sound effect automatic adjustment method, which is used to solve the problem of cumbersome sound effect adjustment operation in the existing recording and broadcasting system. The method in the embodiment of the present invention includes: acquiring the sound signal collected by the sound pickup device; determining the target sound effect mode according to the sound signal and the environmental information of the environment where the sound pickup device is located; performing the sound signal according to the target sound effect mode Adjusting the sound effect; outputting the adjusted sound signal. The embodiment of the present invention also provides an automatic sound effect adjustment device and a recording and broadcasting system.
Description
technical field [0001] The invention relates to the technical field of video processing, in particular to a sound effect automatic adjustment method and device, and a recording and broadcasting system. Background technique [0002] Usually, the construction of recording and broadcasting classrooms includes three parts: recording and broadcasting system, camera system and audio system. Such as Figure 4 As shown, the recording and broadcasting classroom will be decorated with sound-proof materials to achieve the best sound reflection effect. The audio system is mainly used to collect teaching sounds during the class, and then processed by the recording and broadcasting system to obtain the final output. In the recording process of teaching courses, the focus is to collect the teacher's voice completely and clearly, so in many cases, the audio solution will use a hand-held microphone or a lavalier microphone to separately acquire the teacher's voice, and then input the collect...
