目前模拟录音机尽管性能在不断改善、提高,但由于录制原理及机械结构等因素的影响,模拟方式的录音机与数字录音机相比,仍存在动态范围窄、信噪比低、失真率高等许多缺点,要完全解决这些问题在模拟领域是相当困难的,可以说数字录音机的出现,为音频的录音技术带来了一场改革,其两类录音机的性能比较如表1所示。
At present, although the performance of analogue recorder has been improving and improving constantly, there still exist many shortcomings such as narrow dynamic range, low signal-to-noise ratio and high distortion rate as compared with digital recorder because of the influence of recording principle and mechanical structure. To completely solve these problems in the field of simulation is quite difficult, it can be said that the emergence of digital voice recorder for audio recording technology has brought a reform of the performance of its two types of tape recorders as shown in Table 1.
