RX 5 Advanced Audio Editor takes iZotope’s revolutionary Ambience Match technology and makes it available as an AudioSuite process right inside of Pro Tools. This is perfect if you need to fill a gap between two pieces of dialogue, recreate background ambience for a scene, or match ADR to production dialogue. RX can identify the room tone underneath content and seamlessly replicate it.
Let’s look at three ways you can incorporate Ambience Match into your editing workflow.
In this first example, we can see two pieces of dialogue recorded on set, with a gap in between:
The gap needs some room tone to make the delivery sound natural. To do this, select the clip with the two pieces of dialogue and the silence in between them. Then, open RX 5 Ambience Match from the AudioSuite “Noise Reduction” menu.
Click “Learn” to extract the noise profile from these clips. This profile can be saved as a preset (if this is room tone that could be useful later on the project) by clicking to the right of the preset menu and selecting “Add.”
There is a “Trim” control if we need to boost or cut the amount of ambience that will be added, and also an option to “Output Ambience Only.” This can be used to generate ambience and keep it on a completely separate track from your dialogue. It can also be useful when previewing, so that you can listen to the character of the ambience before rendering it.
When you have the sound you want, just click “Render” to commit this to your track. You may want to render this processing onto a separate track or playlist so that the re-recording mixer has access to the original files should they need them.
You can take your dialogue matching a step further by using the EQ Match feature in the RX 5 Advanced Audio Editor. Just send your clips out to RX using RX Connect, learn the EQ profile from the production dialogue, and apply it to you ADR recording. This will work best if you do it after you have matched the ambience.
Let’s consider a situation where you only have ADR or very dry production dialogue, and you want to add room tone to all of it. You could sample room tone from another part of the project, or another project entirely just by selecting that clip and using the “Learn” function. If you don’t have room tone to sample from, you can use one of the built-in presets to generate natural sounding ambience backgrounds, and deliver realistic dialogue and mixes quickly and easily.
Ambience match is available exclusively in RX 5 Advanced Audio Editor, the flagship component of the RX Post Production Suite.
