本文先从理论上简单解释压缩器的使用原理,以及录音后期制作吉他部分使用压缩器的技巧。重点从乐器的动态、功能、色彩入手,以实用性为基础,论述了运用过程,使得经过压缩后的吉他音频减少产生过载现象,又最大限度的表现了吉他音色的动态。 This article first theoretically explains the use of compressor principle, as well as post-production Guitar part of the compressor using the skills. Focusing on the dynamic, function and color of the instrument, based on the practicability, the application process is discussed, which results in the reduction of overload of the compressed guitar audio and the maximum dynamic performance of the guitar sound.
