AI Technical Summary
Technical Problem
In existing sound reinforcement systems, the buffer length has not been optimized according to the specific site environment, resulting in excessive sound reinforcement delay and affecting the sound reinforcement effect.
Method used
In the field environment, the buffer length is first set to the maximum value, and then the buffer length is gradually reduced. By detecting the normal playback of audio data, the optimal buffer size is determined, and the lengths of the first and second buffers are optimized.
Benefits of technology
By optimizing the buffer length, the sound reinforcement delay was reduced, thus improving the effectiveness of the sound reinforcement system.

Abstract
提供一种扩声系统的缓冲区优化方法及装置。该方法包括：将第一缓冲区和第二缓冲区的长度分别设置为其最大值；生成第一音频数据；将第一音频数据提供给播音端，并经由拾音端拾取得到第二音频数据；执行缓冲区优化过程，包括：将第二音频数据提供给算法程序，以得到处理器执行算法程序时输出的第三音频数据；在采用播音端播放第一音频数据和第三音频数据时，检测通过拾音端拾取得到的第三音频数据是否正常，如果是，则减小第一缓冲区和 / 或第二缓冲区的长度，并重复执行缓冲区优化过程，如果否，则将最后一次第三音频数据正常时对应的第一缓冲区和 / 或第二缓冲区的长度作为优化结果。该方法根据现场环境减小缓冲区大小有助于降低扩声延迟。
