How to use denoise plugin in multitrack?

Report · Feb 20, 2019

When I add the denoise plugin (CC 2019) to the effects rack in multitrack, it overworks at the beginning of each track, making the beginning sound like it is underwater, which carries over to when the file is exported.

It works fine in waveform view, but I'd like to use it in multitrack if possible so I can adjust it based on other effects being added, or if I normalize in multitrack.

Does anyone have any advice on how to make this work?

The problem with using Denoise in multitrack view is simply that it's adaptive, and as a result of this it has to work in real time. So its active 'learning' at the beginning of a clip is always going to be audible. In Waveform view it's still adaptive, but it gets a chance to look at the file first before applying itself; it appears to have enough time to calculate a good starting position, and can apply that from the start.

There is no getting around the real-time issue in Multitrack, except possibly by attempting to render the effects on your track first before mixdown - have you tried that?

Thanks for the answer. I tried pre rendering them beforehand, and unfortunately it didn't work.

In just about every instance I've ever come across, it's been better to do the noise reduction on a file before it's been inserted into Multitrack. Aside from any other consideration, you are using up processing power you really don't need to which will mean that there's less for any other processing you're doing. Also it means that you can use the process-based system, which invariably works better than the adaptive one. There are a number of threads on the forum that explain the best way to use it - it isn't 100% intuitive as to how you get the best results, as it involves more than one pass, as a rule. There's a lot of info in this thread: How to Prevent Echo During Noise Reduction

Thanks for the link. I will take a look. I was doing that as a rule before hand, but then if I brought levels up in multi track, it brought the noise back.
