Audio Clip Normalize Including Effects Chain #8

Open JDLJr opened 5 months ago

In DaVinci Resolve 18.6.2 and the public beta release 19: When you normalize an audio clip, the procedure is including the Effects Chain to assess the audio level.

  1. Firstly, normalize the clip without any effects - note the audio levels and the peak display.
  2. Place a gain-changing plugin, such as a compressor, into the effects chain.
  3. Set the plugin up to significantly reduce the gain.
  4. Run the normalize function again.
  5. Disable the plugin.
  6. Compare the audio clip levels now to before.

You will find the clip gain much higher than before, roughly or exactly equivalent to the gain change in the effects chain.

The effects chain should not be included in the audio clip normalize function. The function should set audio levels relative to the audio clip before further processing. This is an industry standard.

To include the effects chain in assessing the level and then applying that back to the clip introduces mayhem.

You can see the result at the input volume for the clip processing.

I've not tested for anything else affecting the clip gain in such a manner.

Changing effects levels down the line are affecting the input level adjustment. This is highly improper.
