Ambisonics surround sound effects Asbjoern Andersen


Ambisonics is a method of recording and reproducing audio in full 360 degree surround – and while it’s not exactly a new invention, recent developments in software encoding have made it a lot more interesting.

And with demand for surround source material skyrocketing with the advent of 3D audio for film and immersive platforms such as virtual reality, Ambisonics is an increasingly useful option.

But how does Ambisonics work in the real world, how do you get started – and how do you make the most it? Experienced Ambisonics recordist and sound designer John Leonard gives you the details in this special hands-on A Sound Effect primer:

The current state of surround sound recording

Before we dive into the world of Ambisonics, let’s look at the current state of the art in recording in surround. It’s pretty easy, but not inexpensive, to make high-quality surround recordings these days, not only with the various discrete array mounts available from a number of microphone manufacturers, but also with all-in-one 5.1 and 7.1 microphones being offered, such as the DPA5100 surround microphone, affectionately known as The Bicycle Seat, and the various offerings from Holophone Microphone Systems.

Both these systems use discrete miniature electret microphone capsules in a special enclosure, with each microphone feeding a separate channel of a multi-track recorder although the smaller Holophone systems can also generate Dolby-encoded surround from a two-channel output, making them useful for DSLR on-camera use.

Aside from its discrete arrays, Schoeps offers a different approach, with a microphone/software system that they call Double Mid/Side, (DMS) where a rear-facing cardioid is added to a standard mid-side pair and the resulting three channels are trans-coded in software to provide a 5.0 surround output. Details here.

Sennheiser has its Esfera system, which uses a two-channel microphone array and separate hardware to generate 5.1 outputs by means of some very clever processing, but at a fairly hefty price tag of around US$12,000 for the complete system. All of these have their advantages, but they all produce horizontal only recordings and, in the case of the DPA 5100 and the Holophone H2-Pro 7.1, require six and eight tracks respectively to record the microphone outputs.

The Ambisonics difference

Without getting bogged down in too much detail, Ambisonics, developed in the early 1970s by Peter Fellget and Michael Gerzon is a way of recording and reproducing surround sound in both horizontal and vertical surround from a single point source. Yes, that’s right: eat your hearts out, DTS:X™, Dolby Atmos™ and Auro 3D™, Ambisonics has been capable of full surround including height and depth for around forty years, and it’s non-proprietary. You can find the relevant Wikipedia entry here for an explanation of the basic science behind the technique.

At its simplest, what’s known as a first-order B-Format surround signal can be generated either by software manipulation of mono sources or by a special type of microphone, using a tetrahedral array of four near-coincident capsules.

The Soundfield Microphone Tetrahedral Array

The Soundfield Microphone Tetrahedral Array

Those from TSL/Soundfield output a B-Format signal, which supplies a matrixed four-channel signal, where the four channels are designated W, X, Y and Z, where W represents on omni-directional reference, X represents front and back, Y represents left and right and Z equals up and down. (This is a gross simplification, but it’ll suffice for this article.) These microphones will have hardware control units that give the user options in terms of gain and directional orientation and filtering and are at the top-end of the market.

The Soundfield SPS200 and the Core Sound TetraMic both output simple capsule feeds and need software (SurroundZone2 for the Soundfield and VVTetraVST for the Core Sound) to correctly matrix the capsule feeds into a B-Format signal.

The resulting four-channel signal can then be trans-coded for output in many ways, from a single source in mono to multi-speaker surround arrays, with the major advantage being that once you have a the initial capture, you can use post processing to vary pan, tilt, zoom and rotate: something that’s not exactly simple to achieve with other systems.

 

Lots of opportunities with Ambisonics:

Ambisonics allows you to transcode your B-format source material into a myriad of formats, by using the free SoundField SurroundZone 2 plugin – including stereo, 5.0, 5.1, 6.0, 6.1, 7.0 or 7.1 surround.

The early days of Ambisonics

The development of Ambisonics was sponsored by a UK government organization called the National Research and Development Corporation, the aim of which was to exploit commercially technology created in the public sector. With Ambisonics, it failed dismally and the technique became the preserve of a few dedicated enthusiasts, but Soundfield Microphone sales continued to those who saw the various uses to which the system could be but, not the least as a pretty impressive stereo microphone for use in recording studios.

The main problem with using Ambisonics in large listening areas such as movie-theaters has always been the size of the sweet-spot, which was pretty small. The effect was still obvious and fairly impressive outside the sweet spot, but didn’t have the wow-factor of artificially pan-potted effects that became the staple of 5.1 and 7.1 movie theater systems. It did, however, give a far more realistic sense of being in the scene than its rather more sensational rival.

Ambisonics evolved

Initially, the decoding hardware was complex and expensive and the lack of truly portable multi-track recording equipment meant that you were pretty much tied to a mains supply and a rack full of gear, but the arrival of sophisticated portable computer interfaces – in my case, the Metric Halo 2882 which could be powered via the FireWire port of a Macintosh PowerBook – meant that it’s been possible to record using Soundfield microphones free from mains power for around fifteen years. Much of the material in my effects libraries has been recorded using this system, although for more portability, I also use Sound Devices 744 and 788 recorders, which have basic B-Format monitoring built-in.

Early location surround recording set-up: Mac PowerBook, Metric Halo 2882 interface and Soundfield ST250 control unit & microphone, Rycote windshield.

Further development in software processing has also meant that expensive hardware is no longer needed for transcoding and, thanks to research carried out at various academic institutions, much of the software to accomplish this is free. The small sweet-spot problem remained, though, and much of the effects material recorded in B-Format by me and others like me, was simply decoded, initially, to stereo and lately, to 5.1 surround, with the height aspect being discarded.

It’s now entirely possible using software, to enlarge the sweet spot, decode for binaural and even to deal with irregular speaker arrays in large venues.

Recently, however, there have been major developments in the use of Ambisonics, particularly with the arrival of immersive virtual reality systems such as the Oculus Rift and it’s now entirely possible using software, to enlarge the sweet spot, decode for binaural and even to deal with irregular speaker arrays in large venues.

One of the developers in the forefront of this technology is a company called Blue Ripple Sound and the good news is that the core software to experiment with this is free, with the caveat that it only works with certain DAWs at the moment, although one of these is the ridiculously cheap, but amazingly versatile Reaper.

Getting started with Ambisonics

If you do want to test the waters and you have Reaper, ProTools, Cubase, Nuendo or Logic, there are a couple of ways you can achieve this at no cost, other than some time to read and understand how to set your system up. There are a number of software plug-ins that will decode audio material recorded as B-Format surround, but probably the first stop should be the plug-in specifically designed to deal with the output of Soundfield Microphones: the company is now part of TSL Products and their SurroundZone2 plug-in is available for VST, AU and AAX systems, with VST & AAX available for both MacOS and Windows computers. You can download it for free here.

If you want a more advanced version, the truly excellent Harpex-B plug-in is available here. It isn’t free, in fact it’s quite expensive, but there’s a thirty day free trial available, which is worth experimenting with.

Harpex-B Ambisonic Decoding

Two instances of Harpex-B Ambisonic Decoding software in use in a complex surround mix, along with two mid/side decoders.

If you’re a Windows user and prepared to dig a little deeper into the system set-up, then you can try Dave McGriffy’s VVMicVST plug-in, which as the name suggests is a VST-only plug-in, although Dave has recently expanded his suite of tools and these can be found on his VVAudio site.

  • Weapons Nocked Play Track 2047+ sounds included $85

    Whether your need to bring a lone rogue to life or a surge of arrows in an epic battle scene, Nocked will provide you with a plethora of flexible content.

    Our largest library to date, this collection is a comprehensive focus on the sounds and functions of the archer and the act of archery. Included are eight recorded bows (2 crossbows, olympic recurve, traditional recurve, longbow, long compound, short compound, and Magyar bow) with 2 additional 'mythic' bows of our own design, each using 3 types of arrows (aluminum, carbon, and bamboo) on 3 varying surfaces (hard, soft, and dirt) from 4 simultaneous recording positions (at bow, at target, midflight mono, and midflight stereo). Each bow and each arrow type have a character all there own.

    The content’s dynamic range is wide, from whispering bamboo arrows gliding on rests as they are drawn to firing position, to the powerful THWACK of crossbow bolts striking their target. All non-firing sounds were recorded in a controlled studio environment while all recordings of the bows being fired were taken on a plot of wide-open rural farmland, encompassed by forests. When needed, this ambient natural environment provided an ideal impulse response to be used in the design and editing of some of the sounds to create a heightened effect.

    Included are a wide array of archery actions and Foley:
    Nocking and unnocking arrows
    Drawing
    Firing (loosing)
    Mid-flight pass-bys
    Releasing / relaxing a draw
    Impacts on targets
    Arrow and accessory Foley (handling, selecting, gathering, dropping, etc.)

    A multitude of takes are provided across each bow/arrow/surface/position combination for easy randomization and differentiation of sounds, or to track any number of unique archers at any given moment.

Included are eight recorded bows (2 crossbows, olympic recurve, traditional recurve, longbow, long compound, short compound, and Magyar bow) with 2 additional 'mythic' bows of our own design, each using 3 types of arrows (aluminum, carbon, and bamboo) on 3 varying surfaces (hard, soft, and dirt) from 4 simultaneous recording positions (at bow, at target, midflight mono, and midflight stereo). Each bow and each arrow type have a character all there own.

    The content’s dynamic range is wide, from whispering bamboo arrows gliding on rests as they are drawn to firing position, to the powerful THWACK of crossbow bolts striking their target. All non-firing sounds were recorded in a controlled studio environment while all recordings of the bows being fired were taken on a plot of wide-open rural farmland, encompassed by forests. When needed, this ambient natural environment provided an ideal impulse response to be used in the design and editing of some of the sounds to create a heightened effect.

    Included are a wide array of archery actions and Foley:
    Nocking and unnocking arrows
    Drawing
    Firing (loosing)
    Mid-flight pass-bys
    Releasing / relaxing a draw
    Impacts on targets
    Arrow and accessory Foley (handling, selecting, gathering, dropping, etc.)

    A multitude of takes are provided across each bow/arrow/surface/position combination for easy randomization and differentiation of sounds, or to track any number of unique archers at any given moment.

    Go ahead, let them fight in the shade.

    Modern Seating is a library compiled of a variation of modern chairs found in the office or home. The idea is to fill the need for chairs which aren't always on the verge of breaking or creaking in every direction. It's a foley library of rolls, pickups and general movement in each type of chair or seat. The library was recorded using the Shoeps CMIT5 and the Avedis MA5.

  1. Great article, but I don’t quite understand this ‘getting started’ paragraph:

    ‘If you do want to test the waters…there are a couple of ways you can achieve this at no cost, …software plug-ins that will decode audio material recorded as B-Format…probably the first stop should be the plug-in specifically designed to deal with the output of Soundfield Microphones.’

    If you need to buy a Soundfield microphone, how is this at ‘no cost’. If you can use your own microphones, how do we ENCODE our recorded sound into B-Format?

    • Hi Christopher, thanks for the comment! Now, I’m not John :) – but I think what he means by that paragraph is in terms of working with existing B-format recordings, ie working with B-format content in your DAW.

  2. Hi,

    Thanks for this great article. I’m just starting to learn the process of capturing and mixing 360 sound. I’m confused though, is the “only” benefit of buying an ambisonic mic just have to do with the ease of workflow? Sort of how it’s best to use a matched stereo pair for stereo recordings if you want the best result with the least hassle? Or is it literally impossible to set up regular mics in a tetrahedron array and eventually get an ambisonic file from that capture, even if it happens in post through a plugin like ambipan or something similar? That seems like it would make sense intuitively since you should be able to use prerecorded mono SFX samples and create an ambisonic environment using a plugin like that…right? Sorry for the novice question. Hope it made sense.

  3. Hello Christopher & Jared,

    Christopher, I did indeed mean that you can experiment with existing B-Format material: there’s plenty of free stuff around – try http://www.ambisonia.com for non-commercial material that you can play around with. Then buy libraries from Asbjoern and keep us poor recordists from starving!

    Jared, Soundfield-type microphones that use a tetrahedral array are designed to keep the capsules as close together as possible, effectively to create a point-source, which will give the best results. My ST450 and my TetraMic are both compact, portable set-ups that can be fitted into shockmounts and windshields and used in the same way as a conventional microphone for effects gathering. It’s possible and quite easy to build an array from conventional microphones for horizontal surround only, and there are various illustrations of rigs that achieve this, using an omni and two figure-of-eight microphones. Do a search for ‘Native B-Format Array’ or go straight here – http://www.radio.uqam.ca/ambisonic/native_b.html for a pretty comprehensive example. You’ll notice that it’s not exactly a compact set-up, though.

    Please feel free to ask anything else and I’ll see if I can help.

  4. Hi,

    I’m doing an audio project for work (completely new to ambisonics/encoding/speaker systems in general, though do have some basic understanding).

    Just to check i’ve got this right, in extreme laymans terms, would I be able to record a piece of ambisonics audio (using for example, a Sennheiser Ambeo 3D VR mic), mix the B format using various different software available, then somehow output it to either a channel based or object based speaker system? (For example, Dolby Atmos or Auro-3D).

    I can’t seem to figure out if Dolby Atmos or Auro-3D are compatible with ambisonics recordings.

    Sorry if these are really basic questions, I’m completely new to file formats and encoding!

    Thanks,
    Lewis

  5. Lewis,

    I’m not sure what you mean by “mix the B-Format” The B-Format signal is what you’ll get after doing the processing from the A-Format (basically capsule outputs) from the Ambeo, the TetraMic or the Soundfield SPS-200. All these microphones have their own processing software to let you achieve this, with varying degrees of precision, and once done, you’ll need further processing to do anything useful with the B-Format. Probably the best bet for transcoding at the moment is Svein Berge’s Harpex-X, which will let you output a multi-channel file that will work with Dolby Atmos or Auro-3D, although it’s not a low-cost option, or a simple one, as you’ll need to use two instances of the plug-in to get the requisite number of output channels.

    There are other options available, but I don’t have time at the moment to go into them at the moment, due to work/life complications. I’ll do my best to expand on them a little later.

    You’re not entering a simple world here, and it’s not a cheap one, either: be prepared to spend lots of time and money. You can download the Harpex manual here: https://harpex.net/manual.pdf

    All the best,

    John
