如何在saw以compressor作 de-esser 的功能???
首先在 saw 的限压(compressor)部份, 我们会看到 key, eq hi , eq lo , key listen 的字眼。
将 Hi Key filter 调 至7khz , Lo key filter to around 6.5khz... (事乎不同音源而定, 一般人声在这范围), 然后按 key listen 听一听 "嘶嘶"声是否在这位置....如果没有问题....可以开始向左移动compressor 门槛(threshold)的推子, 直至看到 gain reduction 的讯号出现时, 留意那个参数最为顺滑....这样便搞定了!! Saw 的 levelizer 也有这功能的, 效果相当不俗!!

Other Notes
Ducking/Cross Limiting
So far, we have been talking about compressors that process the signal that is being used in the level detection process. But in some cases, you would prefer to have a signal's level controlled by a different signal - when one signal level is high, the other signal is attenuated, as in Figure 4. This is called 'ducking' (since it 'ducks' a signal out of the way) or cross limiting. The most common example would be a radio DJ. While music is playing, speaking into the microphone will cause the level of the music to drop so that it's easier to understand the DJ. When mixing in the studio, a ducker can also be used to emphasize certain elements, such as the kick drum. The kick could lower other tracks in the mix, increasing its 'presence.'
闪避处理/交叉限制
目前为止，我们都是在讨论压缩器被用于level detection（信号大小探测）的处理。但在某些情况下，你需要用另外一个信号去控制你当前的信号－当一个信号的音量变大，那么另外一个信号就会被削弱，请看图片4。这个被称为“闪避”或者交叉限制（cross limiting）。最多运用这个方法的就是电台的DJ。在音源正在播放的时候，而当DJ对这MIC说话的时候，音乐就会被触发“闪避”处理，而降低音量，使得DJ的声音更容易被听见。在工作室MIXING的时候，闪避处理器也能用于强调MIX中的主要元素，例如KICK DRUM.KICK在MIX中能比其他的乐器的频率更底，通过闪避处理，提高他的“出场率”。
