3DIO Free Space Binaural Microphone

The 3Dio Free Space is an entry level binaural microphone that allows you to record high quality audio for fully immersive videos, games and more. The Free Space microphone features 2 extremely sensitive primo EM172 microphone capsules that are perfect for binaural recordings allowing you to achieve amazing results. 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.

3DIO Free Space Features

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.

Standard Output
The output of the Free Space binaural microphone is a stereo 3.5mm (1/8") output jack. Simply plug it in to your favorite stereo audio recorder or microphone pre-amp, and start recording true 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.
