However, in special cases, it may be advisable to amplify more microphones in one direction. Due to the speaker in the middle, called the center, which is supposed to play mainly speech becomes superfluous. ![]() 5.1 Surround, Double MSĮven though I am often asked about Dolby Surround 5.1, 7.1 or similar, these formats are not very relevant. Consequently, it takes up more space and may be crucial to hide on a tripod under a 360-camera. Due to the additional time that sounds needs to travel between the microphone capsules and focus on one plane, the localization can be more accurate than in the case of the Ambisonic A-format microphones. This four-channeled by IRT (Institut for Broadcast Technology) shows an alternative to Ambisonics (more on this later). Thanks to a firmware update, it can record in spatial audio mode directly in Ambisonic B-format, only without height information, leaving the third of four tracks in Ambix format empty. Is probably one of the most famous representatives among the 360 microphones mentioned here and still has its right to exist. Hence, no sound can be reproduced above and below the listener, but still may be useful for certain 360 recordings. There are also some interesting applications of surround, which in the classical sense, is also called 360 sound. As a result, I also like to use stereo recordings for 360 videos, even if they don’t "fill the whole sphere with sound". However, I would like to refer to a presentation by Schoeps on the topic Microphone technology for VR. In this respect, the most important representatives, XY, AB, ORTF and Blumlein are mentioned only briefly. Here, too, the application for VR does not appear to be entirely clear at first glance. At least better than the most sound from 360 cameras and therefore mentioned for the sake of completeness. As a result, only one channel will be used and the later playback with dynamic head-tracking will not work. Monoįor this purpose, any microphone can be used, preferably one with an omnidirectional pattern, which records the sound from all directions. Nevertheless, it is worth knowing the approaches in the following. These microphones, or microphone arrays, were usually thought of for later playback on loudspeakers, which is only relevant for VR Audio in special cases.
