欢迎使用Brandon Gono的“压缩简介”音频课程。以下是您将从随附的视频中学到的内容：
视频1-什么是压缩器（08:18）
压缩器实际上是一个推子，您可以对其进行编程，使其实时摆动。混音时的好处是您可以克服不希望的信号电平变化，否则会阻止乐器在天平中保持其位置。
视频2-压缩机参数（17:15）
阈值：确定压缩机将开始起作用的音量级别
比率：确定将超过阈值的物料进行压缩的量。
起始音：确定压缩器对高于阈值的声音做出反应的速度。
释放：确定当声音回落到阈值以下时，压缩器将以多快的速度恢复到正常状态。
增益：组成衰减信号的旋钮。
视频3-压缩混合（20:34）
补充视频，显示我们如何使用压缩来改善混合。
视频4-多频带压缩器简介（03:05）
多频带压缩器是对压缩基本概念的详细说明。多频带压缩器的工作原理是将输入信号分成多个频带（通常为三个），将每个信号发送到单独的压缩器，然后在压缩后再次将信号混合在一起。
视频5-混合多频段压缩（15:18）
另一个补充部分，显示如何在歌曲上使用多频带压缩器。
视频6-串行压缩简介（12:08）
标准压缩器使用范例的一种变体是在同一个声音上使用多个压缩器，它们彼此连锁。这被称为“串行压缩”，在很多情况下，这是一个好主意。通常，多个压缩机作为一个团队一起工作可以比一个压缩机做得更好。
视频7-侧链压缩简介（10:43）
一些压缩器提供“侧链”输入。这是辅助音频输入，允许您使用输入信号以外的信号来控制压缩器的动作。第二个信号称为“侧链信号”。
侧链压缩机的行为与普通压缩机完全不同。它不响应输入信号中的峰值，而是响应侧链信号中的峰值。侧链信号的动态特性用于调整输入信号的动态特性。如果侧链信号超过阈值，则输入信号将相应减少。

Welcome to Introduction To Compression audio course by Brandon Gono. Here is what you will learn from the included Videos:
Video 1 – What is a compressor (08:18)
A compressor is effectively a fader that you can program so that it wiggles around in real time. The beauty of it at mixdown is that you can combat undesirable signal level variations that would otherwise prevent an instrument from maintaining its position in the balance.
Video 2 – Parameters of a compressor (17:15)
Threshold: Determines the volume level at which the compressor will begin acting
Ratio: Determines the amount by which material above the threshold will be compressed.
Attack: Determines how quickly the compressor will react to sounds above the threshold.
Release: Determines how quickly the compressor will return to a normal state when sounds fall back below the threshold.
Gain: The knob that makes up with the attenuated signal.
Video 3 – Mixing with compression (20:34)
A supplementary video that shows how we can use compression to improve the mix.
Video 4 – Introduction to multiband compressors (03:05)
A multiband compressor is an elaboration on the basic concept of compression. A multiband compressor works by splitting the input signal into multiple frequency bands (usually three), sending each to a separate compressor, and then mixing the signals together again after compression.
Video 5 – Mixing with multiband compression (15:18)
Another supplementary segment that shows how multiband compressors are used on a song.
Video 6 – Introduction to Serial compression (12:08)
One variation on the standard compressor usage paradigm is to use multiple compressors on the same sound, chained one after another. This is called “serial compression,” and there are plenty of situations in which it’s a good idea. Often several compressors working as a team can get the job done better than one compressor.
Video 7 – Introduction to sidechain compression (10:43)
Some compressors offer a “sidechain” input. This is a secondary audio input that allows you to use a signal other than the input signal to control the action of the compressor. This second signal is called the “sidechain signal.”
A sidechained compressor behaves quite differently from a normal compressor. Rather than responding to peaks in the input signal, it responds to peaks in the sidechain signal. The dynamics of the sidechain signal are used to shape the dynamics of the input signal. If the sidechain signal goes over the threshold, then the input signal will be reduced accordingly.
