ERA De-Clipper is a simple but sophisticated audio plug-in. Behind the pair of Processing Types (Type 1 & 2), there is a complex algorithm that determines the clipped parts of an audio track and then automatically repairs them. For this reason, De-Clipper usually requires lots of system resources to perform its calculations. The more De-Clipper instances you’re using, the more the power consumption increases.
But how does this affect the performance of Logic?
Logic provides an option to select between a stereo or mono audio track input. You may distinguish the difference between them by looking at the icons.
With this button, you can change the track input from mono to stereo and vice versa. When a track is set to stereo, De-Clipper might not perform as expected, as this is like using 2 De-Clipper plug-ins at the same time on the same track. This will increase the CPU consumption significantly. As a result, it may end creating audio dropouts and glitches.
To resolve these problems, we strongly recommend setting the tracks where De-Clipper is inserted, from stereo to mono. In Logic, you can still process stereo clips even when the track input is set to mono. This will reduce the power consumption of the De-Clipper plug-in, but you’ll still have the same processing results.
I did that, but there are still some problems with my audio!
In this case, you should check the Audio Preferences of Logic Pro, too. Open the Logic Pro X menu, go to Preferences, and select the Audio tab. In this tab, make sure that I/O Buffer Size and Process Buffer Range have the following settings.
