电声技术新进展(待续)

Progress of Electro-Acoustic Technology( Continued)

介绍了电声技术的最新进展,主要从新型扬声器、音频信号处理和声聚焦与声重现三个方面进行阐述,新型扬声器包括高指向性参量阵扬声器和全数字式扬声器系统,音频信号处理技术包括扬声器系统均衡、虚拟低音增强、立体声增强与人工混响等技术,声聚焦与声重放重点介绍了基于扬声器阵列信号处理的定向声辐射与空间声场重现技术。

The latest progress of eleetro- acoustic technology is presented including new loudspeaker, audio signal processing, acoustic tocus and replay. The new loudspeaker includes high directivity parametric array loudspeaker and all - dig- ital audio signal processing technologies. The audio signal processing technology includes loudspeaker system balancing, virtual bass, stereo enhancement and artificial reverberation technology. The acoustic focus and replay introduce the directional acoustic radiation based on the loudspeaker array signal processing and spatial sound field technology.
