６０年代末期，随着数字技术的发展，录音技术也进入了数字化，各种数字录音机相继出现把录音技术带入了数字化时代。数字录音机相对模拟磁性录音机有许多优点，其音频信号的记录、重放采用数字处理后动态范围大（Ｓ／Ｎ大于９０ｄＢ），频响好（１０Ｈｚ－２０ｋＨｚ，±０．
In the late 1960s, with the development of digital technology, recording technology has also entered the digital, a variety of digital voice recorders have appeared in the recording technology into the digital era. Digital recorder has many advantages compared with analog magnetic recorder. The audio signal is recorded and replayed with a large dynamic range after digital processing (S / N greater than 90dB) and good frequency response (10Hz-20kHz, ± 0).
