The DJI Mic 2 is the corporate’s newest moveable wi-fi mic system, designed to ship high-quality sound – and particularly to allow clear vocals – with out the fuss that usually comes with sophisticated pro-level audio gear.

This second-gen mannequin rivals the Rode Wi-fi Professional, boasting some thrilling new DJI tech that features 32-bit float audio seize and AI-powered ‘clever noise discount’. In brief, straight out the field (or ought to I say charging case) you can begin recording audio in auto mode, even in advanced environments, with out worrying about clipping, or the distracting noise round you.

These good pro-level options are packed into the identical fool-proof design because the DJI Mic, with dependable magnetic mounts for fast mic setup along with your topics, and an instantaneous sync between mic and receiver.

The whole package consists of two transmitters (mics) for dual-channel audio (protecting two topics or a single topic with stereo sound), one receiver, a charging case, wind shields, and a lav mic, plus the mandatory connectors, with all of the parts squeezed right into a tiny carry case. At $349 / £309 / AU$529 for the whole package, the DJI Mic 2 is a dream bit of drugs for these engaged on small video productions, and for solo content material creators who don’t have the posh of getting a devoted audiofile on set.

Why all of the fuss about 32-bit float?

In brief, 32-bit audio has a higher dynamic vary than 24-bit – which is the vary of the first-gen DJI Mic – at 192dB to the unique DJI Mic’s 144.5dB, whereas 16-bit is barely 96.3dB. Nonetheless, 32-bit float (not a set frequency level) encodes wider values and has a possible vary that covers as much as 1,528dB.

What do these numbers imply in actuality? For one, 32-bit float can utterly keep away from audio clipping – for instance when the sound all of the sudden goes actually loud. Audio clipping is a serious stress for filmmakers on set and in submit manufacturing, for whom 32-bit float generally is a godsend.

To make use of a digital pictures analogy, it’s type of like taking pictures uncooked as a substitute of JPEG – with uncooked you possibly can get well far more high-quality element that will in any other case be misplaced with JPEG when the publicity is just too brilliant or darkish, or higher right colour temperature when it’s off. So even if you happen to get it flawed at seize, you possibly can nonetheless prove a good last picture.

Should you had been to nail the publicity and colour appropriately on the level of seize, then JPEG format is ample, and in the identical approach, if you happen to set audio acquire appropriately from the beginning, 24-bit ought to sufficiently seize audio frequencies. Nonetheless, the fact for a lot of video productions is that audio merely can’t be monitored simply on set, the place something can occur, together with sudden excessive frequencies like your topic shouting into the mic. Whether or not you’re an beginner or a professional, 32-bit float is an enormous deal for audio recording – it is the convenience of auto audio, with the pliability to deal with the sudden.

Along with 32-bit float, DJI has launched AI noise discount that successfully reduces environmental noise. Whether or not you’re travel-vlogging from a bustling metropolis road, wandering echoey convention halls at an occasion, or coping with the hum of highway site visitors or an air conditioner fan in earshot of your interviewee, DJI’s clever noise discount may turn into a super-handy device, guaranteeing most potential vocal readability.

One other new device is direct Bluetooth connection between digital camera and transmitter, successfully bypassing the DJI Mic 2 receiver – ideally suited for the instances you’d slightly not join the receiver to your cellphone (or DJI Omso Pocket 3 / Osmo Motion 4). I ought to level out that if you happen to go for that connection technique, you lose the power to file in 32-bit float. You can too go for Security Observe, which information a backup second monitor at -6dB ought to there be extreme audio spikes. Neat.

If you need participating video content material, great-quality sound is important, however reaching that’s simpler mentioned than carried out. For vloggers and small video manufacturing outfits, who are sometimes working in high-pressure shoots with restricted assets, the highly effective, good and no-fuss DJI Mic 2 is an excellent possibility.
