Pertaining to frequencies of a normally audible sound wave (15 to 20000Hz). Audio has been, until recently, a very neglected side of video recording and processing. Very often, during videotape duplication and enhancement, the quality of the soundtrack is detrimentally affected. Several special soundtrack enhancement devices and integrated audio and video enhancers* have lately appeared on the market (see Audio Equalization and Audio Exciter). New VCRs and TV systems employ Hi-Fi quality sound tracks, and are sometimes equipped with decoders for DOLBY SURROUND*, AC-3* or other three-dimensional sound encoding devices.
相关于正常的可闻声波(15赫兹到20000赫兹).声频技术直到现在仍然是录象和相关处理的一个非常被忽略的方面.但是,在录像带复制和处理时,声音质量是受损伤了的.近来,几种特别的声处理设备和成套声频和视频处理器已在市场上出现.(见声频均衡及声激励器两个条目).采用高保真音质的声轨迹的新的VCR和TV系统,有时要备有为杜比环绕声,AC-3或其它三维声编码系统用的解码器.
OK.这就是这段英文的中译.不知有没有耐心读完.
这段英文大概是十几年写的,和当代技术成果比,是落伍了.
其实,这里面的细节在专业人士圈里,也是要不断学习的.
对于大众来说,恐怕就是在正确的时间买到正确的东西,
当然是合理的价格啦.
