November 14, 2019: Facebook Reality Labs released two photos of their
6-degrees-of-freedom research dome. It is instrumented with 420 Core Sound TetraMics.
Each TetraMic first-order ambisonic microphone is individually
calibrated for the highest precision sound source location cues.
OctoMics offer even
higher precision location cues!

Zoom released the new v4.0
firmware for their F8 recorder today. It features support for
first-order ambisonic microphones, including TetraMic.
We recommend using the F8's "Ambisonics A" mode. That mode configures
the F8 to record TetraMic's four A-format tracks, while also allowing
you to monitor in real-time via speakers or headphones.
By recording in A-format you'll retain the ability to apply your
TetraMic's unique calibration files. Those files make your TetraMic into
one of the world's finest ambisonic microphones. But even monitoring
without the calibration files, TetraMic is pretty fine.
At first listen, the Zoom monitoring function decode seems to be XY

yet, so we can't tell you what angle they selected between the virtual

We recently heard from the noted sound
designer/supervising sound editor Paula Fairfield. She told us that she
used TetraMic widely for the 2016 Robert De Niro film "Hands of Stone".
May 15, 2017:
TetraMic was used as part of
Marshall Day Acoustic's IRIS
measurement system to test and commission
the Jiangsu Grand Theatre in Nanjing China.
April 25, 2017:
TetraMic was used by JJ Wiesler
(Pollen Music Group) on Google's Oscar-nominated short animation
"Pearl". It was used to record singer Kelley Stoltz performing "No Wrong
Way Home" from the viewer's perspective in the passenger seat of a
car. It was also used to capture IRs.
You can watch and listen to "Pearl" on YouTube: https://www.youtube.com/watch?v=WqCH4DNQBUA.
February 5, 2017:
We've further improved TetraMic's
industry-best calibration procedure, making location cues even more
accurate and reliable. No other first-order ambisonic
microphone even comes close.

VVTetraVST v1.8 for Mac and
Windows is now available for download from the VVAudio web site:
November 11, 2016:
Bosse Sandholm did a few live
recordings comparing his TetraMic to a soon-to-be-relased ambisonic
microphone from a major manufacturer. The results confirmed the reason
why we calibrate each and every TetraMic individually: much better
location cues and much more natural sound quality.
You can download the files here. Decode them
into Blumlein for stereo playback, or into surround, and you can confirm
what we're saying for yourself.

Station Film used TetraMic to
record the audio for their 360VR dark comedy short "Red Velvet"
. You can see TetraMic at
the lower right corner at 0:11 and later at 1:14 in "Station Film: Red Velvet (Behind The

using Google's Cardboard viewer. (TetraMic is wearing its furry/foam windscreen.)
June 24, 2015: Since we introduced it a few
months ago, the PPAc has been an overwhelming success. It's the best way
to power TetraMic. It's compact, reliable, allows for powering via 48V
phantom power or an external 9 Volt battery pack, and allows separations
between TetraMic and the recorder/pre-amp of 850 feet or
more. It's also less expensive than the previous PPA2 and PPA3 packages.
As a result we've discontinued the PPA2 and PPA3 options.
February 12, 2015: Marshall Day Acoustics' IRIS
system was used in the acoustic design of the new Philharmonie de Paris
concert hall. IRIS uses TetraMic as its sensor.
You can see Simon Rattle's glowing review of the hall's acoustics here:
November 2014: Jaunt's virtual reality
camera is using TetraMic as its audio sensor. It's being used in the
field to record virtual reality cinema. In this photo TetraMic is
wearing its furry/foam windscreen.
September 23, 2014: Based on TetraMic user
feedback we can we can highly recommend the Tascam HS-P82 multi-channel
digital audio recorder for use with TetraMic.
April 3, 2014: Jaunt VR's virtual reality
camera prototype uses TetraMic as its audio sensor.
March 21, 2014: We're pleased to announce two
new phantom power adapters - in addition to PPA2 - for use with
TetraMic. PPA3 is a short cable that plugs directly into a recorder or
mixer - no extra XLR cables are necessary. PPAc is a small
transmitter/receiver pair, provides power for all four channels and
sends TetraMic's audio over a CAT5/CAT6 cable up to 850 feet long.
June 10, 2013: We're pleased to announce that
in addition to offering a precision calibration service for SoundField
Ltd's SPS200, we are now also offering calibration for their Mk IV
too. The results of our calibration far exceed what those two
microphones come with from the factory. Please contact us for details.
July 28, 2012: Now you can use an iPad to

easily powered by a battery for mobile use.
July 14, 2011: The RME
Fireface UFX is another digitally controlled mic pre-amp that works
well with TetraMic.
November 17, 2009:We've replaced the Phantom
Power Adapter (PPA) with a new model that maintains phase, instead of
inverting it as the older model did. The new PPA2 will ship with all
orders placed after December 1, 2009.
