Demo summary

The user demonstrates how to split a file into stems, apply an EQ module specifically to the music layer, and gain down specific effect stems within iZotope RX 12.

Step-by-step

Open the Stem Split module and select Scene Rebalance.
Click Process and wait for the AI to generate the stem view.
Select a specific stem layer, such as Music or Effects, to isolate it.
Apply a module, like EQ, to the individual stem and click Render.
Adjust the gain on specific stems to reduce unwanted sounds.
Export the final result as a total WAV file.

Options

Select specific pieces of audio to process instead of the entire file
Apply different modules (EQ, Gain, etc.) to individual stems

The processing time for stem splitting can be significant (up to 5 minutes depending on the file).

Tips

Use the gain tool to drop specific effect stems by 30 decibels to fix issues missed during the initial edit.
