AVAR Conference: Using MEMS Microphones for Ambisonic Audio in a Live Streaming Spherical Video Camera
Presenter:Lucas McCauley, VideoStitch - Paris, France
Abstract:
A few months ago, VideoStitch announced the Orah brand and its Orah 4i, a live streaming spherical camera, complete with immersive audio. The 4i uses four lenses and realtime stitching algorithms to produce 4K spherical video and four on-camera MEMS microphones to capture first order ambisonics. The output can be streamed directly to any platform that accepts live feeds of immersive content. This workshop explores the design of the Orah 4i camera’s integrated ambisonic audio capture, from selection and placement of the microphones, capsule correction EQ, level matching, omnidirectional to cardioid polar pattern processing, and conversion to first order B-format. The final design decisions and several measurements are shown.
Price: This session is part of the co-located AVAR Conference which is not included in the normal convention All Access badge.
