The Free Space binaural microphone is the most affordable, high-quality binaural microphone on the market. The integrated Primo EM172 microphone capsules are extremely sensitive and quiet. The EM172 capsules have a very natural presence, perfect for binaural recordings. The Free Space delivers portable, professional quality binaural in the palm of your hand. The Free Space has a very warm and solid response in the low to mid-range frequencies. This brings out the punch as well as provides low-end support for bass-heavy sounds. The frequency response of the EM172 capsules used in the Free Space rolls off slightly above 10kHz. This is excellent for recording instruments with loud high frequencies like drum cymbals or strummed acoustic guitars. It also prevents any harsh effects that are sometimes associated with binaural recordings using smaller capsules.
The microphone works well in windy conditions even without protection. Wind sounds realistic without affecting the binaural experience or overloading the microphones.
The output of the Free Space binaural microphone is a stereo 1/8" (3.5mm) output jack. Simply plug it in to your favorite stereo audio recorder or microphone pre-amp, and start recording 100% pure binaural audio.
The Free Space comes standard with a 5/8" microphone stand adapter installed in the base. The microphone stand adapter is removable. The base of the microphone has a 1/4"-20 female thread mounting hole that can be connected to a hot-shoe adapter or used to mount directly onto a tripod or grip handle.
The Free Space contains a 9V alkaline battery within the chassis. The battery is used to power the microphone capsules.
Why does it sound so natural?
The Free Space captures sound just like we hear sound in the real world with our own ears. When you listen to a recording captured with the Free Space using headphones or 3D capable speakers, you hear the sound as if you were there at the time of recording. The effect is so powerful because the Free Space design is based on 13+ years of research into binaural technology and human hearing.
The Free Space uses matched Primo EM172 hi-sensitivity capsules.
Every microphone ships with an 8" long 1/8" stereo M2M cable.
