I’ve had the opportunity to record live musicians in a couple of different in-the-field scenarios for 360 video content. In some situations — such as the ubiquitous 360 rock concert video — simply having access to the board feed is all one needs to create a pretty decent spatial mix (although the finer points of that type of mix would probably fill up a whole different article).
But what if you’re shooting in an acoustically interesting space where intimacy and immersion are the goal? What if you’re in the field in the middle of a rainstorm without access to AC power? It’s clear that in most cases, some combination of ambisonic capture and close micing is the right approach.
What I’ve found is that in all but a few elaborate set-ups, a mobile ambisonic recording rig (in my case, built around the Zaxcom Nomad and Soundfield SPS-200) — in addition to three to four omni-directional lavs for close micing — is more than sufficient to achieve excellent results. Last year, I had the pleasure of recording a four-piece country ensemble in a few different locations around Ireland.
Micing a Pub
For this particular job, I had the SPS and four lavs. For most of the day I had planted one Sanken COS-11 on the guitar, one on the mandolin, one on the lead singer and a DPA 4061 inside the upright bass (which sounded great!). Then, for the final song, the band wanted to add a fiddle to the mix — yet I was out of mics to cover everything. We had moved into the partially enclosed porch area of a pub with the musicians perched in a corner about six feet from the camera. I decided to roll the dice and trust the SPS to pick up the fiddle, which I figured would be loud enough in the small space that a lav wouldn’t be used much in the mix anyways. In post, the gamble paid off.
I was glad to have kept the quieter instruments mic’d up (especially the singer and the bass) while the fiddle lead parts sounded fantastic on the ambisonic recordings alone. This is one huge reason why it’s worth it to use higher-end Ambisonic mics, as you can trust them to provide fidelity for more than just ambient recordings.
In another recent job, I was mixing for a 360 video of an orchestra. During production we moved the camera/sound rig around to different locations in a large rehearsal stage in London. Luckily, on this job we were able to also run small condensers into a board for each orchestra section, providing flexibility in the mix. Still, in post, the director wanted the spatial effect to be very perceptible and dynamic as we jump around the room during the lively performance. The SPS came in handy once again; not only does it offer good first-order spatial fidelity but a wide enough dynamic range and frequency response to be relied on heavily in the mix in situations where the close-mic recordings sounded flat. It was amazing opening up those recordings and listening to the SPS alone through a decent HRTF — it definitely exceeded my expectations.
It’s always good to be as prepared as possible when going into the field, but you don’t always have the budget or space for tons of equipment. In my experience, one high-quality and reliable ambisonic mic, along with some auxiliary lavs and maybe a long shotgun, are a good starting point for any field recording project for 360 video involving musicians.
