Can someone explain the TetraMic to me?
The more I read the description of this product the more I just feel ignorant. What's the ideal application for this thing?
Core Sound — TetraMic |

A single point multi-microphone placement for recording surround sound.

Re: Can someone explain the TetraMic to me?
Read up on Ambisonics (specifically) and surround sound (generally).
Two good places to start: Ambisonics https://en.wikipedia.org/wiki/Ambisonics An Introduction to Ambisonics https://www.creativefieldrecording.c...-introduction/ And RODE's been teasing an on-camera ambisonic mic (stemming from their acquisition of surround audio pioneers SoundField). I don't see the right link on the Rode website, so check out this text + video: https://www.dvestore.com/rode-videom...ic-microphone/ Fun stuff. A lot of work to record and post...

Re: Can someone explain the TetraMic to me?
Also have a look at the Calrec Soundfield history as they marketed the system in the 1970's and we still us their mics on most sports in the UK.
I heard a wonderful demo of the last night of the proms from the Albert Hall 25 years ago: https://en.wikipedia.org/wiki/Soundfield_microphone More here: http://decoy.iki.fi/dsound/ambisonic...ll_dB_1982.pdf

Re: Can someone explain the TetraMic to me?
Ambisonics is great for VR work, because just like VR cameras have a camera pointing in each direction, so do these microphones, they point a mic in each direction.
Then just like when you're seeing 360VR content you only see a portion of the whole image, using the cameras mixed together in the direction you're looking in, so is the same with VR audio, you only hear the audio mixed appropriate for the direction in which you're looking. I've been using a SoundField SPS200 myself for the past week on VR shoots, great fun!

As I'd be very curious about what its price is, and its real world performance.
