The dual microphone processing feature of ERA-D is a patented technology which enables you to repair difficult recordings previously thought to be headed for the cutting room floor.
ERA-D can work in Dual Mode using two sources as an input. For example, a camera mic and a boom mic. Each one of these microphones can capture different elements of the acoustic scene and provide new cues to ERA-D's modern algorithm, leading to superior restoration.
As always, this is just one example. You can use any secondary microphone to improve the audio repair quality of your primary source of interest.
How do I open the ERA-D track in Adobe Premiere?0
As described in the ERA-D | Walkthrough Tutorial #2: Dual source, the routing for this processing requires two tracks and a stereo aux track that will be the ERA-D track.
In Adobe Premiere, there aren't Aux tracks, so in order to work in Dual Mode, we need to create a Submix track, which we will use to sum the audio from the two microphones.
To open a Submix track go to Sequence> Add Tracks and add an Audio Submix Track
Make sure that the Track Type is Stereo, otherwise the trick will not work. Then open the Audio Track Mixer so you can have access to the mixer.
And how do I route my tracks to the Submix Track?
Before routing anything, pan the camera microphone hard left and the boom microphone hard right.
Then set the output to the Submix track for both of the tracks.
Now, it's time to insert ERA-D on the Submix track. Open the inserts panel and select ERA-D in an available slot.
Note: If the insert slots are closed, you can re-open them.
I'm all set! Do I have to set up anything on ERA-D?
Yes, a couple of things and you are ready to go! Open the window of ERA-D and:
- Set the Dual mode on both De-Noise and De-Reverberation sections in order to engage the dual mic processing.
- Select the Channel in the Output section, so that the plugin outputs only the channel source that you want to use, in this case the R (Right) channel which is the Boom microphone.
