What differentiates an Indie film from a major Hollywood Blockbuster? (Besides the fact that the Indie is probably better ;)?)
It’s not the special effects, the anamorphic lenses or the super technocranes…
It’s the quality of the sound.
Sound is extremely important to filmmaking – in some ways more than the images themselves. Sound helps to fill out the space we are seeing on screen. It makes the image immersive and clues us into the environment of what’s being shown to us, so that we can deduce what is happening beyond the screen’s edges.
You can look as far back as Fritz Lang’s 1931 thriller, M, to see examples of how off screen sound can be used to create tension or imply the existence of something beyond the screen’s edge. In that film, Lang uses the familiar tune of the killer whistling to foreshadow his arrival on screen or create his presence without actually showing him. Skip forward 41 years to 1972, when Walter Murch was named the first ever "sound designer" on Apocolypse Now by director Francis Ford Coppola for his creative contributions to the film’s audio track. Since then – Sound Designers have been an integral part of filmmaking. I for one will never release a narrative film of any length without it going through sound design first – no matter the deadline!
To that point here’s a great mic that I’ve been playing with for a little over a month that I wanted to share with you. I was contacted by the maker a few months ago and asked to try it out. The moment I recorded my first clip with it (at the base of the Golden Gate Bridge – a shot you’ll see in the video above) and laid the audio down on the same track as the video – I played it 20 times in a row. Literally. I felt immersed in the shot – and it reminded me of the quality of audio that I heard in the opening battle scene of Saving Private Ryan. Given that I didn’t have to mix anything or do anything fancy with the audio in post – I was hooked.
I’ll be the first to admit that I’m not an expert on Audio. But I do know good sound – we all do. What amazes me about the audio within the clip above and the Mitra 3D Mic Pro is that it’s raw audio out of the mic and recorded on a Zoom H4N. It hasn’t been mixed: no equalizing, bass boosting, trebble tweaking done YET. And it sounds amazing.
A similar result can of course be obtained by a skilled audio technician with two mikes, positioned accurately and mixed together. The beauty of this for me is that I am not a skilled technician – and was able to get audio like this right out of the box using a $300 audio recorder.

The basic thing you need to know about this microphone, is that it has two high quality mics that are spaced apart roughly the same distance as your ears are from one another. It also utilizes a sound modifier technology which captures immersive sound just like we hear it. Most, if not all mics out there are mono mics – and a normal stereo microphone cannot record the same information in the same manner. The beauty of this system is that you can handhold the Mitra mic or put it on a small tripod and let it roll. Just monitor your levels and you can have this incredibly immersive sound out of the box. You can then mix it into 5.1 if you want as well.
I think every film crew that needs good, natural sound should take a look at one of these – especially time lapse photographers/videographers. It adds an ENTIRE NEW DIMENSION to your video. There are two versions – the PRO and INDIE versions which differ mostly in the XLR outputs and related electronics, however both mics have the identical sound processing engine, and both record the same quality audio.
Special thanks to TJ Walker from Boombox Group Productions for allowing us to use the footage from our shoot on Alcatraz. More to come on that soon…
Wow :-O
Any sound difference between the Pro and Indie versions? $700 vs. $1000 makes the Indie version worth considering…

There is no sound quality difference between 3D Mic Pro and 3D Mic Indie. The only difference is- 3D Mic Pro has two XLR outputs in addition to a stereo line level 3.4 mm phono output, while Indie has only one stereo mic. level 3.4 mm phono output.
Indie has been designed specifically for DSLR filmmakers. Each and every Mitra 3D Mic is hand made in US with top of the class components and carries limited lifetime warranty.
Amazing! What where the quality settings on the H4N?
Thanks for posting the clips!
Wow, wow and wow!
These are one of those “have to get one” products.
I think this is definitely the next stage for the indie shooter – we’ve already stepped up with picture resolution, price, and depth of field. Now it’s time to supercharge the soundtrack!
Most people call this binaural technology, and it’s behind the famous Virtual Barbershop youtube clip. Check out the difference between true binaural recording and post-simulation with a plugin here: http://www.soundplusdesign.com/?p=426
To my ears the processing by the 3Dmicpro guys is a little harsh – like using too much sharpening on an image. But I love that they’re getting it out there.

The binaural tech is amazing. I agree with you that this is a great next step for indie/time lapse shooters to add a new layer to their productions.
@Robert, Stereo WAV at 48kHz/16bit
I foresee some very interesting POV videos where that mic is mounted right-atop the DSLR. If you have a well-staged scene, the simple addition of stereo panning will add mountains to the viewing experience.
What about dialogue, is it any good for that?
There is a fair amount of clipping on a few of those clips. For the record, I’m checking this audio through Apogee D/A on both Sony Professional MDR-7506 headphones and KRK Systems Studio Monitors. I don’t think it’s the mic, sounds more like just hot gain levels clipping the pre’s on the Zoom H4.
Aside from that, the spacial definition and immersion is excellent. Certainly a nice compact solution for the exact type of clips that were used in this demo video. Loved the Golden Gate Bridge shot (aside from the slight clipping and high end brittleness).
That’s really awesome. If you haven’t heard it already you really should check out this audio track. It’s truly erie and strange to see how you can make 3d sound when simply wearing a pair of headphone…

I agree with the others, it has a good sound- perhaps a bit sharp- but surprisingly deep for such a small unit.
I’ve been using the now discontinued Audio Technica AT-822 (http://www.audio-technica.com/cms/wired_mics/665bdf92967733dc/index.html) for stereo location sound for well lover a decade and never understood anyone who needs good location sound using a single shotgun. A shotgun can’t give you as good source-specific sound as a lav (wired or wireless) and it’s a phase limited mono sound source.
So using a good, single-point, stereo mic for high quality nat sound is not new, just new to some.
AT now has four stereo mics and you can certainly find a decent one for under the $1000 (list) of the 3D Mic Pro. I’m not knocking this mic, but it’s just one of many quality stereo mics available. What it lacks is a bit of directionality- the trolly car had so much ambient and reflected audio in it that, at first, you almost can’t tell which direction it’s coming from. A directional stereo mic would have nailed the audio for that shot.
Can you post a screen shot of your timeline in post so we can see how the audio was mixed?
Hello!
Nice Vincent!
You should check out this page about sound and HDSLR. Great work from Marius Arnesen:

Unfortunately it is in Norwegian, but you will understand a bit just by watching this image:

Hey Vincent,
Just wondering – how does the Mitra compare to the cross-angled mics on the front of the Zoom H4N? Big difference?
Also, on a somewhat other note, you sometimes hear sound guys recording nat sound (i.e. w/o voices) from the environment that they use to cancel out ambient noise. Do you know how this process works? Can you show this in Adobe Audition CS5.5?
Thanks.

not even close – huge difference
Sounds like any other Stereo XY mic flash recorder.
The Mono shotgun is how virtually every sound should be captured then with those stems a sound designer or musician creates their soundtrack.
Stereo (3D) miss make little sense.
Photographers need to learn a thing or two about sound because Mono doesn’t equal AM Radio therefore Stereo is better, shotgun miss, lavs, studio miss are mono for a reason – ISOLATION.
Hey Vincent…
Picked up a Mitra and got it in today. So far it’s quite impressive. However it seems to run a little hot into both the H4n and the 5D Mark II. Do you suggest an an XLR attenuator by chance? If so -20db??? I don’t anything about them, but thought it might be the answer to some of the near peaking. On the 5D I am only one click from the bottom on the Manual control and down to .7 on the H4n.
All the best… Charles
this 3d mic will sweep off movies…the sound is truly more realistic…sounds is the greatest effect for me when it comes to movies…kudos to this new gadget
Amazing! this 3D mic is perfect for the movie makers. It makes sounds more realistic then when it comes to movies or theater this 3d mic is what their looking for.
awesome.. Thanks for sharing.
Fantastic site. A lot of useful info here. I’m sending it to several friends ans also sharing in delicious. And naturally, thank you on your effort!
Why aren’t there any independent reviews of the Mitra? Before I open my wallet I want to see independent reviews and tests.
