yes indeed. perfect example. and easily applied to gaming (i use that adjective with tongue approaching cheek). imagine the laser quest with HUD in a room, with virtual fighters, and true sound placement around you. kids would (of all ages) pony up large money for such an experience. but for me, i'd really like some tools to use in film mixing (even with the distributed Ls and Rs speakers). anyone on the list care to tell me what tools might be best, or why it just won't work? the idea is to simply improve location and immersive aspects of film sound, whether played in a theatre or in home theatre. (yes, assume the home has a decent home theatre playback, and by decent, i include something like a Bose-qulality system with 5 small satellites --not full range-- and appropriate sub, such as the one bob ludwig uses at Gateway for clients to listen on as a real world living room). would G format *not* benefit this type of setup at all?

Low order Ambisonics has trouble with this. While we happily denigrate 5.1, it is always worth remembering that it was designed to work in these hostile environments.

I assume by the UK you mean the UK Government. The UK Government, through the National Research Development Corporation, strongly supported the development of Ambisonics; they paid for it. While the NRDC had strange ideas on how to market Ambisonics, there were no legal restrictions on them doing so. in addition, when MAG openly criticized (and mathematically gutted) the Quad stuff, he did not make friends with many in the industry and they made sure he was sidelined.

Re: [Sursound] OT: Spatial music
Meridian may be expensive, too, but at least they are sticking with Ambisonics. Full horizontal 1st order B-format is now included in their decoders, as well as UHJ, superstereo and Trifield. Oh, and I'm a Meridian customer enjoying one of the few (only?) current domestic ambisonic decoders. Still damned expensive, so I've not replaced mine for nearly 15 years. I could just about cope with full 2nd order horizontal (6 speakers) but not 3rd with eight speakers in my typically small UK sitting room. Height is out of the question, People clearly put 5 and sometimes 7 speakers in their listening/entertainment rooms (in all sorts of odd places, though), so G-format should be possible, too (up to 3rd order?). For home use, I use superstereo with the TV and, as long as the width control is kept narrow-ish, centrally based sounds tie in well with what's happening on-screen. Sounds-off, such as doors closing and people speaking about to come into the image from left or right, can give a nicely widened perspective on a performance. I've only really been used to UHJ as a home user so I'm looking forward to full 1st order for music, classical and otherwise. I'd love to try UHJ with the TV. I suspect the dominance of a large TV image will tend to direct (sharpen?) perception of sound source positions on a TV screen, as happens anyway with TV speakers placed well off centre. Cinema may be a non-starter but not home use. IMHO I can't see how FOA isn't clearly worth promoting along with up to 3rd order G-format decodes for 5.1/7.1 setups for home users. Basically, get UHJ and, while we are at it, superstereo into people's homes, then get on with full 1st and higher orders.

First order is certainly fine for classical orchestral music, and I enjoy that as well even without Meridian's help. It works also for all sorts of other music that wants to create swirling sound scapes, etc. We're not trying to help blind people to target shoot by sound, we're essentially looking for artificial musical sound effects and natural sounding ambience. But that will reach a minoriy classical music lovers audience only. And first order fails rather miserably for anything else compared to 5.1 which is what people already have and can compare with. Essentially nobody listens to music in surround format, particularly not in a mass market. Also, I rather have less precise spatial resolution than what might be achievable with 5.1, but have it sound natural, not the sound out of speakers that most 5.1 productions end up having. Besides, G-Format would also end up being 5.1. It won't produce a stable front channel for movie sound, nor has it the the required spatial definition for effects that work outside a very small sweet spot. Movies have no reason to switch to Ambisonics. The visual dominates the ear, and so there's no need for natural sound, because we're absorbed by the movie, and the movie studios are not going to change their production workflow or their love affair with DTS/Dolby anytime soon. So Ambisonics for movies is utterly irrelevant, at least until such point that it has proven to be a resounding success in music. And what's the problem with five or seven channels anyway ? Three things: cost, cost, and cost. The cardboard speakers that ship with affordable 5.1 systems are not suitable for music, and anything halfway acceptable is on a good sale at least $250/speaker, which means with four speakers you're at or above $1k, add a decent four channel amp, cables, speaker stands, etc. and you're well above the typical consumer price level already. This isn't about what grant money can buy in a computer lab, this is what a waiter, someone making $1500/month, etc. i.e. the typical iPad/AppleTV buyer could afford, not what a doctor or lawyer would buy if only they had a clue about technology. This has nothing to do with 'elitism'. Try selling 256-color computer displays to today's consumers. Won't work even if they would do fine for 99% of all practical computer applications. It's too late for that. Technology has moved on, and people know it. Technology hasn't moved on. 5.1 is 4.0 plus a crappy center speaker that has a totally different tonal quality and never blends with the other four lousy speakers, plus a subwoofer to make up for the fact that the other speakers are lousy. Four full-range speakers in a 4.0 configuration is better than what 99% of people have in their homes, and cost near what they could possibly afford. To talk about higher channel count is totally disregarding economic realities. Further, it's also not about Madonna or some stars who have the budget and access to engineers who might actually understand what they are doing. This is about the majority of musicians who record themselves, or who go to some local dude with a computer and analog mixing desk that sounds horrible but looks impressive to have their music produced. These people are not going to ever understand spherical harmonics, nth order something or another. They can intuitively grasp front-back, left-right and mono. They will be able to make a stereo CD (UHJ), and have an extra gimmick to sell: now you can listen to your CD in surround sound. Nobody is talking about stable images, just as little as The Beatles stereo recordings were Blumlein stereo. But they can make sounds swirl around, and people who do location recording can get a decent ambience. All of that is better than what is accessible to most consumers, musicians, and recording studios today. It is breadth that will get something like this going. It's not the best that is winning, but the most accessible. Once limited Ambisonics is sufficiently adopted, then it's time to show that there's more to this. You're not going to get people to mix single tracks with the channel count that e.g. 2nd order requires unless there's already established demand for surround music. There are also no decent tools around, no DAWs with built-in support for 2nd or 3rd order Ambisonic production, and they won't be, because nobody is going

Steve Steve, Anthony: In which sense is UHJ and superstereo a viable alternative to 5.1 surround, if 5.1 is clearly better than any 2-channel system can be? You should introduce something which exceeds the existing solutions, not going back to something which fits into the stereo distribution chain. We already had this. I have written that you could decode a 3rd order .AMB file on a 4 or 6 speaker home installation, for example ignoring the 2nd and 3rd order components. 8 speakers would be even better, but less is still possible. (You can watch a 1080p movie on an underspecified SD television, or a 720 line TV. The loudspeaker number above is just the equivalent. Downsizing a format to a device with lower resolution is mostly not an issue. You also can watch a photo on a computer screen, even if the resolution of a current digital camera is certainly much higher than any computer monitor can show.) Anthony: You should read what people (this means: me! :-) ) say, not what you would like to read. For example, I never said anywhere that music should be distributed on BD discs. (Have been here a long time before. This is probably just history. IMO the distribution of surround music via UHJ stereo tracks belongs into the same category. Listen to UHJ if available and if you can decode this, but don't promote this for the future practical distribution of surround, because 5.1 already exists.) I said that Apple doesn't support BD movies on any Mac OS version. I don't buy into the excuse that the Blu-ray DRM (AACA/BD+ support) would break the Mac OS architecture, which would be a longer discussion. But I have actually more important things to do than to discuss these issues here, honestly. (Historically: Apple had pretended they would finally support Blu-Ray, in 2005/2006. They didn't tell it would not be possible. The bag of hurt story was invented way later. ) I don't have to promote Ambisonics, specifically I don't have any plans to replace 5.1 with FOA. What is the huge deal about? (Both formats have advantages and disadvantages, compared to each other. You also have to consider that 5.1 can be mixed or recorded in very different ways, and some or actually pretty convincing. For film, 5.1 is probably superior. You could say that FOA has been unfaily neglected which is probably right.) If you promote G format, 99% would see and listen to this as a 5.1 surround file. (An 99% would listen to an UHJ as a stereo file, cos there are really very few decoders around. In fact, 5.1 seems to be way more mainstream than decoded UHJ.) Therefore, don't push for stereo-matrixed (UHJ) or pre-encoded (G format, 5.1) Ambisonics variants in 2012. In fact, Apple (or Microsoft, Google Music (?), Sony Music Unlimited or whoever sells movies/music) should firstly offer 5.1 surround files. It doesn't cost anything to offer another surround format in an online shop, if music/audio is available in this format. The consumer could chose. But if you offer something beside 5.1 surround, I believe this should be something better. Not something reduced. Try to find solutions which are viable for the next 10 or 20 years, and don't go back 20 years. (Sorry for being slightly polemic, but I think this is a valid argument.) Surround tracks are sold via the Internet, there are plenty of existing online shops. The problem is that you would have to sell 5.1 (or FOA...) tracks of well-known music, which means the hits. The Majors are missing this opportunity. (Plenty of recordings ae available, which means many thousands.) As a musician, I am participating in plenty recordings which are done also in 5.1. In this sense, don't call me elitist, or whatever. But FOA probably won't make it. The time of UHJ has been. I am not sure that any form of surround will make it into the home, but I think there is still a real chance that it will happen. The iTunes shop is currently irrelevant for surround music, and there are more companies around than Apple.
