Spatial Editing: Removing Sounds From Specific Directions
« on: November 06, 2023, 07:06:33 AM »
Did you ever want to remove sounds that are coming from a specific direction, like a talker or a cougher?

Well, you can do that now.

Spatial Domain Editing

Did you ever really want to somehow remove an audience cough in an otherwise quiet classical music location recording?

With a higher-order ambisonic recording and well-designed plugins, you can use spatial filters to remove sounds coming from specific directions.

Here's an example of how to remove an audience cough from a higher-order ambisonic recording using Blue Ripple's spatial audio plugins:

First-order microphones don't offer enough spatial resolution to do this well. So a higher-order microphone (like OctoMic) is required.
