Coronal Audio announces DuoMic: three new mic-ing techniques for recording surround or hemispherical 3D sound with only two microphone capsules.
These new mic-ing techniques differ from current 2D or 3D recording techniques, by:
- the number of involved microphones, e.g. compared with an A-Format Spherical Harmonics device,
- the versatility of the recorded signal, which allows transcoding to multiple formats, like matrixed surround or First-Order Spherical Harmonics (FOA), hence allowing to rotate the space, e.g. compared to binaural recordings.
Among their advantages:
- they reduce the microphone hardware requirements, space, costs,
- they reduce the recording device requirement, as a simple stereo recorder is sufficient.
Applications are in numerous domains:
- smartphone or GoPro or 360 video recording devices attachment or embedding,
- audiovisual & VR production, immersive recording, ambiance recording,
- telecommunications, telepresence, robotics.
More details about these patented technologies will be released on October 1 at the Los Angeles AES AVAR conference, during the Longcat workshop.
