From macOS 10.13 (High Sierra) on, under some circumstances newly installed AU plugins are not found directly after installation.

Rebooting your computer usually solves this. Alternatively – if you feel comfortable using a command line terminal – you can restart the AudioComponentRegistrar service by opening a terminal (under /Applications/Utilities/Terminal) and entering the following command:

killall -9 AudioComponentRegistrar

Dynamic Grading

We understand where you’re coming from: there are graphs that look like a spectrum analyzer, and somehow you can adjust what looks like crossover frequencies. But take a closer look!

Those scales are in Decibels, not Hertz. So what you’re seeing is not the typical spectrum analyzer display, but a histogram of loudness levels that occurred within the analysis time window. Consequently, think of the graphical handles more as a way to adjust thresholds, ratios and makeup gains that result in a more advanced gain curve that is applied to your dynamics. By the way, you can display that curve by clicking the curve button.

There are no crossovers and no frequency ranges involved in this product. It all works in a broadband way.

Yes you can! In Dynamic Grading, you can easily adjust the output level by moving all target handles (the ones to the right) at once. To do this, just grab the middle of the target body range and move it up or down.

Similarly, you can move all handles together by grabbing the middle of the source body range on the left. This corresponds to adjusting an input gain and at the same time compensating the output gain in opposite direction, which is useful when you want to adapt to a changed input level in a neutral way.

Dynamic Grading internally maps the graphical handles to multiple parameters. Thus when you move these handles, multiple parameters are changed at once, and you DAW will not know which one to assign the controller to if you use a MIDI learn function.

Depending on your DAW you might be able to manually assign controllers to parameters. Please refer to your DAW’s manual to find out how to do that. Here’s an explanation of the relevant parameters, for reference:

  • Source/Target Body Level: The center of the body ranges
  • Source/Target Body Range: The radius of the body range around the center level
  • Source/Target Punch/Floor: The size of the punch/floor ranges

Dynamic Grading is designed for you to easily tailor settings for the audio material at hand, using the combination of dynamic histograms and in-place graphical editing. As a consequence, a specific setting only makes sense in conjunction with specific source audio and can hardly be transferred to other (even similar) recordings.

This is actually a problem with many dynamic plugins that come with lots of factory presets: they usually don’t fit your situation, and thus aren’t very helpful. In Dynamic Grading, you would notice right away when a random “Female Lead Vocals” preset doesn’t have anything to do with the reality of your specific female lead vocal track.

Trust us, you don’t need factory presets.
