Again, even with a higher quality and more sensitive microphone, there is a limit to the physics of what it can capture. With Firmware v 2.0, it’s perfect for the creation of 360-degree “Spatial Audio” files, the next-generation surround sound format native to the google JUMP Virtual Reality Platform. This means that you can connect it to your PC and record directly to your favorite DAW , without having to … (J360), which focused on exploring some of the simplest ways to work in an immersive medium with a compact and portable equipment setup. . Plan your disappearing act Sennheiser MKH418 mid-side shotgun microphone, DPA 4060 omnidirectional lavalier microphones (several on Zaxcom RF beltpacks, plus a stereo pair), Sound Devices MixPre-6 multichannel recorder, Roland R-05 stereo recorder (for 4060 stereo pair). That’s it for the recording options. Our audio engineering team also explored new territory — combining sound-rich and immersive audio with in-depth reporting and narrative. (Andy Huether/NPR). It’s also helpful to announce the orientation and direction of these claps e.g., “Front!” ? 360° VR virtual reality Zoom H2N ambisonic mic hire & rental – London, UK The industry refers to this as “head-locked” audio. Clap in two or three directions around the rig to make audio/video syncing easy on the backend. Point source is a term used to distinguish standard, single-source audio from ambisonic audio. There are a lot of fas­ci­nat­ing opti­miza­tions and expla­na­tions of ambison­ic and spa­tial audio pro­cess­ing avail­able to read at Wikipedia: The orig­i­nal in-cam­era audio (Ricoh Theta S records in mono) to com­pare can be viewed here: http://www.matthiaskronlachner.com/?p=2015, Sony Noise Cancelling Headphones as Binaural Microphones, BioCity's Discovery Building with Corona display - 360 Video and Photographs, Using CSS Parameters to Stop Content Shifting with Dynamic Vue/React Content, Mikrotik Script — Wake On LAN All Devices from DHCP, Lockdown fun with Stop Motion Photography, Telepresence Internet Controlled 4G/LTE Long Range Robot Car, How to watch the NTU Falcon Cam on PC, Mac, iOS and Android (Updated 2019). With these technical details in mind, let’s explore our production from our trip to Puerto Rico, where we captured the story of restoring electrical service to remote locations that had been without power for months after Hurricane Maria. Once we got to the island, the environment and our subject matter dictate our equipment choice and setup. It does this with multiple capsules, usually arranged in a tetrahedron with four capsules (or more), each pointing in a different direction. Mainland contractors about to be lifted by helicopter, rigged with lavaliers and a Zoom H2n for spatial recording. Over prepare. I had a try adding spa­tial audio to a VR video. Next I import­ed the audio and video tracks, and cut them to syn­chro­nize to when I clicked my fin­gers together. “Left!” ? FuMa is an older convention; ambiX is a newer convention used by Facebook and YouTube. . Be sure to align the camera and microphone orientations. Don’t count on being able to clearly capture far-away sounds with the ambisonic microphone; consider adding these distant sounds as point sources in post. (Andy Huether/NPR). If you have your sound recorder ori­en­tat­ed incor­rect­ly, you can cor­rect it using the plu­g­ins. Here are some additional terms we’ll use: Binaural audio delivers a full 360-degree soundscape through a specially encoded stereo file that has to be experienced through headphones. This is a successful and popular demo of binaural audio: Ambisonics or 3D audio delivers a full 360-degree soundscape that is responsive to a visual field. This provides audio signals from various directions that can then be encoded into a binaural or ambisonic/3D audio for listening on headphones or other setups. It took an extra five hours of wait­ing for the spa­tial audio track to be processed by YouTube. I also had lavaliers fitted to the workers with beltpacks that could record locally, however they quickly went out of range of my wireless equipment as the helicopter flew away to a remote location. Record for at least three minutes For example, we found that turning the microphone upside down made the fuzzy windscreen more subtle and easier to stitch over and hide in the final video: Be sure to align the camera and microphone orientations. It is most common to work in ambiX, but there are tools available to convert FuMa to ambiX. AmbiX and FuMa  are two conventions for B-Format ambisonics used to determine channel ordering and weighting. Extra audio ensures smooth transitions, creates options for editing, provides an additional ambi bed if needed and more. In addition to slating the main rig recording, keeping track of any additional recordings becomes critical when planning supplementary point sources. audio recorded with a lavalier, shotgun, stereo mics, etc.). An ambisonic microphone is designed to capture raw ambisonic audio. Pay particular attention when inverting the microphone as above; always notate microphone orientation and continue to keep the front of the microphone aligned with the camera zero. Left: Mobile kit for capturing additional points sources and interviews. Four channels of audio will be recorded as a single multichannel WAV file. Roll, pitch, yaw are the three axes of head movement. into 360-degree video began as part of the. We placed the ambisonic mic in the position we thought was best, and then placed other mics around the space to capture isolated sounds up close. “Left!” ? If you’re interested in looking at more examples of 360 video, check out this video we produced using sound effects in lieu of field recordings to create an immersive listening experience. is designed to capture raw ambisonic audio. (Nick Michael, NPR). All of the basic tips for recording in 360-degree video, that we outlined in our last post remain relevant. Keep notes, audibly slate, and/or rename files. It is most common to work in ambiX, but there are tools available to convert FuMa to ambiX. (Andy Huether/NPR). We separated the bridge plates with a longer threaded rod to accommodate a larger microphone and rigged the multichannel recorder to hang either between the tripod legs or strapped to the base of the monopod. Here are some additional terms we’ll use: audio delivers a full 360-degree soundscape through a specially encoded stereo file that has to be experienced through headphones. The industry refers to this as “head-locked” audio. Different models of ambisonic microphones must have their raw A-Format recordings converted to B-Format to be compatible in post-production and for final delivery to content platforms like Facebook or YouTube. I ori­en­tat­ed the cam­era so that the record but­ton was fac­ing toward me, and the Zoom H2n’s LCD dis­play was fac­ing away from me. The first time I met someone who did spatial audio for VR experiences, I immediately apologized. For these, I was able to capture audio with the Zoom H2n for spatial audio (not full 360; it can capture front and back but not vertical information). This can also be used for live streaming. As with most audio recordings, the closer the microphone to the source, the better the signal-to-noise ratio. The three axes of head rotation, left to right: roll, pitch, and yaw. Andy Huether is an audio engineer at NPR. We separated the bridge plates with a longer threaded rod to accommodate a larger microphone and rigged the multichannel recorder to hang either between the tripod legs or strapped to the base of the monopod. “Back!” ?. is a standardized, multi-channel audio format for ambisonic audio. In my case, I used the Z‑axis rota­tion to effec­tive­ly turn the recorder around. By using with a 360-degree camera, you can deliver 360-degree VR live streaming, which moves the audio image along with movement of viewpoint on Facebook and YouTube. The only selectable recording formats are 44.1 or 48 kHz and 16 or 24-bit WAV formats. The video produced from this trip shows the evolution of our team’s approach to 360 video and the value of additional audio production work. I cre­at­ed a new project in Adobe Pre­miere, and a new sequence with Audio Mas­ter set to Mul­ti­chan­nel, and 4 adap­tive chan­nels. We Support Your Stage! Here we find a Tuner and a metronome, pretty straight forward! We only had a few weeks for this production. Don’t count on being able to clearly capture far-away sounds with the ambisonic microphone; consider adding these distant sounds as point sources in post. This guidance applies to both the main ambisonic rig and additional point source recordings. Keep the ‘room’ small The Zoom H2n is a popular, affordable and amazing microphone favoured by spatial audio and Ambisonics practitioners worldwide which comes bundled with Google's professional Jump VR …
