Is it possible to make multiple selections on the timeline, then apply one module preset to correct them all at once?
Ref. : iZotope product manuals : RX 11 manual :
Hold down shift after making a selection in order to add another, separate selection. If any part of the new selection overlaps any other, the selections will be grouped into one. This can be especially powerful when combining several selection tools to create multiple selections of different size and shape.
Based on your initial post then I am not sure if I understand you correct but :
The Batch Processor allows you to process multiple files at once with a custom module chain, streamlining time-consuming tasks. The Batch Processor can run simultaneously with the RX Audio Editor, allowing you to process in bulk while working in RX.
.
Files can be added to the Batch Processor window by using one of the following methods: Click the Add files button at the top of the Input section. Drag and drop files or folders from Finder (Mac) or Windows Explorer (Windows) into the Input files section of the Batch Processor window. Folders that are added will retain their folder structure in the output directory.
Add multiple files from the same folder by holding the Command key (Mac) or ctrl key (Windows) when selecting files from the Finder or Windows Explorer dialog.
Thanks for the prompt reply. I was looking at Batch Processing.
