Products DJIlike the drones in the series Phantom e Mavic, are widely used by both professionals and enthusiasts. The advanced technology of stabilization and the intelligent features integrated into DJI devices make it easy to create quality visual content. In addition to drones, DJI’s business focuses on the design and production of stabilizers, gimbals and cameras.
In mid-January 2024, DJI also presented the new DJI Mic 2 microphone, which was created to support the so-called 32-bit float recording. It is an advanced device equipped with a function noise cancellation intelligent, a tool that presents itself as an ideal choice for those who want record audio high quality when shooting with your digital camera.
What is meant by 32-bit float audio recording
The 32-bit float recording refers to the bit depth at which audio data is captured and stored. While traditional 16- and 24-bit audio recording is widely used for the vast majority of multimedia work, 32-bit float mode offersdynamic amplitude significantly higher.
The bit depth refers to the amount of information that can be represented in each audio sample. With a 32-bit float approach, the dynamic range is extremely wide, allowing you to capture subtle sonic details and nuances that might be lost in recordings at lower bit depths.
The pattern offered by a device such as the microphone DJI Mini 2, provides greater flexibility during the post-production phase. Audio engineers, for example, can make changes without worrying about losing information or introducing artifacts. Additionally, if the input level is too high, 32-bit float recording handles the overload keeping the information on the “softer” parts of the sound intact.
How to connect the DJI Mic 2 microphone with a camera
When you open the DJI Mic 2 charging case, the receiver automatically starts up and connects to two transmitters. The touch panel on the top of the receiver shows the battery life and internal recording capacity (expressed in hours of recording).
One of the distinctive features of the DJI Mic 2 is its ease of use and the flexibility of connecting with different cameras. DJI Mic 2 features a “preset function” which allows you to recall the settings of I earn predefined for each camera model: simply indicate the brand and model of the camera using the touch panel so that the receiver applies the optimal settings.
Think of all those (common) situations in which there is some noise which disturbs the audio recording: think of the buzz in a rather crowded room, the sound of an engine, PC and server fans, air conditioners and so on. In these situations, DJI Mic 2 gives its best by clearly capturing, for example, the voices of the subjects directly involved in a confrontation, without any unwanted noise.
The DJI Mic 2 transmitter normally acquires 48 kHz, 24-bit audio information; With 32-bit float recording, however, you can record with zero noise without having to adjust the microphone input level. The final touch is precisely the function of smart noise cancellation: It can effectively eliminate background noise, allowing voices to be recorded clearly without interference.
