如何使在Logic Pro中的多波段管压缩机
Mike Watkinson on Thu, October 13th 4 comments
While Logic Pro 9 comes bundled with a very capable Multiband Compressor it lacks the circuit types found in the standard compressor. Mike Watkinson wires up a solution using Aux channels.

Logic Pro中hasn't了一个专用的多波段管压缩机插件。有一些猜测,同一压缩机电路类型选项在逻辑标准压缩机的插件将添加到版本9 MultiPressor,但它并没有被。也许在Logic Pro中X?在此期间,您可以构建自己的使用辅助渠道。也许它不是最快的方式来创建一个信号处理器,但你可能更容易理解它是什么做!

多波段压缩机背后的想法是,你可以申请到不同频段,不同的压缩设置,真空管或阀门内置的情况下,每个频带可以利用独特的声音特性的优势,这些组件可以借给健全尤其是当驱动硬盘


创建3个频段的多波段管压缩机:

  1. Add three stereo auxiliary channels by clicking the ‘+’ button on the far left of the mixer (choose the first available bus as the input, and tick the ‘Ascending’ box)
  2. Set up a send to each auxiliary channel from the channel that contains the file you are mastering
  3. Set send levels to 0dB by Option-Clicking on the send level
  4. Add a low-pass filter to the first Aux channel (the low end signal), and a hi-pass filter to the third Aux channel (the top end signal) and set the cutoff points to taste
  5. Add a High Cut and a Low Cut filter to the second Aux channel (the mid-range); this is in place of a bandpass filter which Logic does not provide. Set the cutoff points to coincide with those in the lo and hi-pass filters
  6. Add Logic’s Compressor plug-in to each auxiliary channel (after the filter)
  7. Set each compressor to the circuit type of your choice (see below)

现在你可以适当的设置,每台压缩机:一个平行的压缩方法是设置门槛低,比例高,创造理想的失真文物,再搭配使用辅助通道输出推子的信号与压缩这些。

作为一个使用过滤器来控制频段的替代品,你可以使用的过滤器(每个AUX通道之一)MultiPressors,独奏适用波段,在每个插件的实例,在MultiPressor设​​置压缩比为1:1,使插件,而不是由压缩机压缩处理。

虽然是在逻辑文件没有提供任何信息,似乎普遍认为,在逻辑电路类型压缩机用以模拟以下经典压缩机:

  • Platinum: Emagic’s own compression algorithm
  • Class A_R: Neve 2264/33609; the R is for Rupert. This would be vacuum tube style compression
  • Class A_U: Vari-Mu e.g. Fairchild 670/Manley. Again a vacuum tube emulation, but designed to be more transparent than the R.
  • VCA: DBX 160/SSL G-Master buss compressor
  • FET: Urei 1176 or similar
  • Opto: Teletronix LA2A or similar

    Excellent tutorial. I like the idea of using the Multipressor as a frequency splitter. This can come in handy as well to split the frequencies up and apply different effects other than compressors on the different frequency bands for.

    Yes - that's a great idea. I particularly like the way you can easily decide to split frequncies into 2,3 or 4 bands! Thanks for the comments Mike Watkinson

    Does anyone know - Do I need to do this tube compression if sound was already coloured by compressor while it was at mix? Because to colour 2 times the same sound I think isn't a good idea...

    Well...the amount of colour you decide to add is completely up to you and what your ears decide. Sometimes a track will need a lot of colour - sparse hip hop for example benefits from extra colour and crunch; busy mixes with lots of distorted sounds (guitars, vocals etc.) might suffer from too much colour. What's important is to have a range of tools available to you so you can tailor your production to the needs of your ears (and your clients of course!)...
