NPR: A guide to recording spatial audio for 360-degree video
« on: December 12, 2018, 07:39:46 AM »
I thought this may be interesting for those hopping into the Ambeo world.

As immersive video formats grow in popularity, NPR audio engineers have been experimenting with techniques for how to record high-quality spatial audio — an audio format that allows a listener to experience sound in all directions.

NPR’s initial foray into 360-degree video began as part of the Journalism 360 Challenge (J360), which focused on exploring some of the simplest ways to work in an immersive medium with a compact and portable equipment setup.

During a recent trip to Puerto Rico, I helped engineer a rich, immersive audio-video project on the aftermath of Hurricane Maria. Our audio engineering team also explored new territory — combining sound-rich and immersive audio with in-depth reporting and narrative.

As an audio engineer, I was asked to join the project to focus explicitly on high-end immersive spatial audio. This meant two things: First, capturing audio from the camera position with a higher-quality microphone and recorder setup. And second, using more advanced techniques and tools in post-production to enhance the final product, including adding additional audio recorded separately from the main spatial rig.

In this post, we provide a detailed look at recording spatial audio from an engineer’s perspective. It will be most useful for those with a basic understanding of audio engineering fundamentals. We’ll use our recent trip to Puerto Rico to demonstrate one example of an immersive spatial audio workflow.

LOL @ gear list
The primary equipment we used in this project:
  • Sennheiser Ambeo ambisonic microphone
  • Sennheiser MKH418 mid-side shotgun microphone
  • DPA 4060 omnidirectional lavalier microphones (several on Zaxcom RF beltpacks, plus a stereo pair)
  • Sound Devices MixPre-6 multichannel recorder
  • Sound Devices 788T multichannel recorder
  • Roland R-05 stereo recorder (for 4060 stereo pair)
  • Zoom H2n 2/4 channel recorder
  • Zaxcom TRXLA3 wireless beltpack/recorder
Please DO NOT mail me with tech questions.  I will try to answer in the forums when I get a chance.  Thanks.

Wonder how hard they lurked this board.
Minus the Zaxs, they are ready for the Phish's OTS with a OMT setup.
