动态范围压缩(DRC)是音乐制作中经常使用的一种过程。传统上，实现该过程是为了控制节目素材的动态范围，以最小化记录设备过载的可能性。然而，随着时间的推移，DRC变成了一个更多地作为创造性效果而不是作为预防性措施应用的过程。在专业录音环境中，工程师接触到几种不同类型的DRC设备并不少见，每种设备据称都有自己独特的声学特征。本文通过对三种流行的老式动态范围压缩机进行大量的测量，研究了它们之间的差异。使用THD测量、音调突发以及使用频谱分析和音频特征提取对基于音乐的材料进行客观分析来测试压缩器。
Dynamic range compression (DRC) is a much-used process in music production. Traditionally the process was implemented in order to control the dynamic range of program material to minimize the potential of overloading recording devices. However, over time DRC became a process that was applied more as a creative effect and less as a preventative measure. In a professional recording environment it is not uncommon for engineers to have access to several different types of DRC unit, each with their own purportedly unique sonic signature. This paper investigates the differences between three popular vintage dynamic range compressors by conducting a number of measurements on the devices. The compressors were tested using: THD measurements, tone bursts and objective analysis of music-based material using spectrum analysis and audio feature extraction .
