自从1970年国际上研制数字录音机,就开始了数字音频设备的工业实用化的发展阶段。七十年代中相继出现了与专业模拟设备混合使用的单机形式的数字式音频设备,如降噪器,延时器,混响器,及多声道数字录音机等。数字设备的失真小,噪声低,动态大,多次复制处理质量不下降等特点,逐渐为大家所重视,但由于设备价格高,基本上限制在专业方面少
Since 1970, the international development of digital audio recorders, digital audio devices began the industrialization of the development stage. Seventies have been mixed with professional analog devices stand-alone form of digital audio equipment, such as noise reduction, delay, reverb, and multi-channel digital voice recorder. The distortion of digital equipment is small, the noise is low, the dynamic is big, the quality of duplicating and processing does not decline and so on, gradually pay attention to by everyone. However, due to the high price of equipment, it basically restricts less professional aspects.
