I noticed this when I did the update to DJI GO 4. .... I was watching my recordings and heard myself breathing LOL! I was so confused for the first few minutes but then remembered, when i first opened the APP my Iphone asked me if DJI GO 4 could access the micorphone.
You can turn this off by going to Settings, Privacy, Microphone - and deselect DJIGO 4.
I discovered this the first time I did a live video feed to Facebook from the drone. The phone's mic is recorded and broadcast over the web along with the proxy cache footage from the drone's video link.
As for the motor noise, I can foresee in the not to distant future, noise cancelling technology that will be able to cancel out motor, wind and other mechanical noise from the drone itself, so it can record audio. Because the mic is in a fixed location in this hypothetical futuristic drone, the DSP technology can use other mics to sample the rotor noises and a DSP and processing algorithm can subtract that noise from the audio picked up by the mics in realtime. Think about noise cancelling headphones. The principle is the same. |
