New Rode 16 Channel 360' Mic
  • This plus an iTouch looks like a much better solution that those 3D mics floating around for me. Love the concept. @PhillipBloom adds his usual high standards of reviewing to the launch video.

  • It's official - look at Philip Bloom's April Fools Page: http://philipbloom.net/2013/04/01/canonraw

    Interesting, though, he does mention that some day this might be true! After all, the Canon Raw thing is already sort of true (BMC) and it's actually cheaper than the Canon was.

  • Yeah sure I'm going to buy this and next year they'll come out with the i32 and I'll look like an idiot with my 16 mics..!

    (:

  • @MirrorMan

    So - all that means is that it can record for a full five minutes with a fully charged battery. Easy to get around - just buy 20 iTouch devices and rotate them to achieve a reasonable day's shooting;)

    Or, wire four car batteries in series for power. You could use them as weights for your tripod - very stable! And you will only have to recharge once every few months (mostly because of self-discharging) even with full days of shooting...

  • Mates, I agree with the idea in general. I am also big fan of surround sound, I've recorded all my sound productions since 2004 in surround. Preferably 2+2+2 instead of 5x1.

    But I don't want to go off topic, I just feel like an April Fool regarding this 16mics device :-)

    BTW for my personal taste Rode's capsules I know sound tad too sharp, but the sound of different capsules vary as much as is the case with different lenses. But this is now off topic....

  • How can it not be an april fools joke? The capsules look to be the same as the NT4 and the NT5 which would mean needing phantom power and I doubt the iPhone is capable of providing that. Its also not on listed in their product line anywhere on the website.

    Ahaa, but there is the iXY which looks quite handy. Anyone tried this? http://www.rodemic.com/mics/ixy

  • @cbrandin You might find the new Dolby Atmos theater sound system interesting as it employs a similar application of sound source virtualization technology. The processing is inverted of course, since it's a 3D loudspeaker array rather than a microphone array. I heard a technical demonstration in the Dolby theater and the dynamic 3D effect was uncanny, especially the simulation of someone walking up behind you.

  • @tetakpatak

    I see other advantages to array microphones, aside from normal recording considerations:

    Noise suppression - achieved by differentiating out sound data from other directions.

    Narrow pickup pattern from normal capsules - achieved by processing proximate capsules. In fact, you could tune the patterns to a certain extent.

    Surround - obviously.

    Virtual capabilities in post - you could create virtual channels from the array such as narrow pattern channels in various directions with noise suppression for dialog and surround ambient channels, then mix them as if they had been captured with separate devices. MS configurations, etc... You could pretty much pick what you want in post.

    Teleconferencing companies have array systems that make relatively distant sources sound like they are close up - could be some interesting possibilities there.

    Capsules and reasonably high quality opamps and AD converters are so cheap these days that their cost is insignificant compared to the case you put them in. Why not consider designs with lots of capsules?

  • Here's an interesting array microphone - but it's $15,000: http://mixonline.com/products/review/audio_trinnov_srp_surround

    You can buy decent capsules for really cheap these days. Seems to me someone could replicate this kind of thing for less than 1/10th the price using today's technology.

  • A true array would respond to changes in environment, or consist of an extremely large number of small microphones that have network profiles. Otherwise there is no reason to have an array, since it is easy using MADI to hook up a few dozen mics to one cable and create the virtual array in post. Another intriguing way to use arrays is use certain mics for certain frequencies, in the way that a speaker uses different drivers with a crossover.

    Here's a simple array anyone can try (with cheaper alternatives): a Schoeps MK2H or DPA measurement mic (Oktava omni) for the bass, Sennheiser MKH 40 for the mids (Oktava cardioid) and an Earthworks QT 30 or 40 for the treble (RODE small diaphragm omni). You have to create EQ curves to smoothly handle the crossovers. Tie the three together with rubber bands (or silicon O rigns) to retain phase and isolate against noise.

    If you like ribbon mics, but are disappointed in the top end and bass extension (they don't have either) you can create a gorgeous sound by using such an array with a ribbon mic--or coincident pair of ribbon mics--in the middle of this array, and then blend the treble and bass in to extend the range from 20 Hz to 24 kHz.

  • Well, they changed the date on their announcement to April 1. Looks like a prank after all. Thinking about it array microphones could be pretty interesting, but not arranged in a wheel. It does get me thinking about properly designed array microphones, though.

  • I made a mistake. I just noticed: "Combining the Mid-Side and X/Y mics together allows full 360-degree surround sound recordings in either 2-channel or 4-channels. In 2-channel mode the sound is recorded to a single stereo file, while in 4-channel mode two separate stereo files are recorded to provide more options when it comes to post-production"

    I didn't see that in Zoom's VST module . Will have to look more closely. Maybe I can do even better with this $125 gadget...

  • Most of my audio is recorded live, from whatever mics happen to be within range, and it would be nice to be able to steer a VST null (to get rid of extraneous background sounds) or a peak (to focus on the subject). So Rode's idea is something I have considered myself. Perhaps not 16 capsules, however... The next best thing has been the MS mode of my new H2N...

    I read that the figure 8 element of the H2N is actually two small cardioids back-to-back. Pity they don't record all three channels (M,S1,S2), that would lead to some excellent flexibility in post...

  • Something like eight microphones around with four each up and down.

    @cbrandin When I read this, my first idea was what @trevmar already wrote, to use two H2n's if you like this idea in general.

    And although we're probably April Fools this time, it was also my point what @DrDave described better: the problem of such a device is the fact, that one would must position all sound sources around it. Separately positioned mics will always sound better.

  • Microphone arrays have been used now for about ten years. The basic fact is that ten mics that you can position will always sound better than ten mics stuck on a wheel or whatever.

    BUT when you get up to a hundred minimics on say a large dish, computer controlled with a network and micro servos, then you create a different world of sound. This thing is basically a weed whacker style. Even with good mics, they should be detachable, either wirelessly or on spring cables.

  • April Fools - but - I purchased a Zoom H2N at $125 a month or so ago. It records MS, and they give you a VST plugin which is rather nice in post. Especially when the mic is very close to the sound source and the image needs to be trimmed down in width a little.

    ps: it records in XY front, XY rear (4 channel) or MS, and I have been using it mainly in MS...

  • Hmmm. Suspicious timing.

  • Boy, if this is an April 1st joke it will inspire me to design something like it - but in a more spherical array. Something like eight microphones around with four each up and down. Their choice to use a two dimensional array is somewhat confusing.

  • Gee - now you guys are down to killing the messenger. A lot of snark from a bunch of people who have never seen a microphone array before trashing the guy who actually used the product. Unimpressive and irrational...

    Microphone arrays have been around since 1975 (at least). They weren't popular because they were very, very expensive, and very difficult to use properly. With as cheap as electret elements are today, and as much as signal processing has advanced (in price, quality, and ease of use) it seems to me that all this is pretty viable today.

  • If there was anyone left who was in any doubt that Bloom's opinion can be bought, that video says it all. This thing is a total gimmick. "Better than what my actual ears could hear"... makes me cringe.

  • Just in case you want to learn about microphone array processing (and you're somewhat of a masochist): http://www.idiap.ch/~mccowan/arrays/arrays/tutorial.html

  • Ha, ha, I find it very funny if it is really 1st April joke :-)

  • @Siddho You are making some very naive assumptions about how surround sound and signal processing work. Even with simple systems currently in use there is not a 1:1 mapping between microphones and speakers. Instead sound is mapped into a virtual soundfield according to microphone configuration, and then it is remapped into a soundfield according to speaker placement. Also, the microphones don't need to be particularly narrow field - signal processing can be used to calculate a narrow field response area from multiple not-so-narrow field microphones. Granted, it might take some time to work out all the signal processing as approaching sound capture this way is relatively new - but rest assured, it will come.

    Geez, for a bunch of guys into the latest and greatest visual technology, there are some real Luddites here when it comes to new ideas for sound capture;)
