How do I record all four DJI Mic 3 transmitters as separate tracks on an iPhone?
Set the DJI Mic 3 receiver to Quadraphonic mode, plug it into the iPhone's USB-C port and open CamPlot Recorder. It asks iOS for every channel the receiver sends, shows a meter for each transmitter, and records each one as its own track: one four-track WAV, or four mono WAVs if you prefer.
Does it keep recording with the screen off or the phone in my pocket?
Yes. Once you hit Record it keeps going with the screen locked and the phone in a pocket. Stopping takes a deliberate hold, and the file is saved every two seconds, so even a dead battery doesn't lose the take.
What happens if someone calls during a take?
iOS lets a ringing call take the microphone from any app, so CamPlot Recorder tells you before you roll whether a call could get through, and shows you how to switch on Airplane Mode with Wi-Fi off. The receiver keeps working because it's plugged in. If a call does get through, everything so far is saved, the phone buzzes, and the take carries on as the next part.
What files does it make?
Broadcast WAV at the receiver's sample rate (48 kHz on the DJI Mic 3), 24-bit or 32-bit float. Every file carries time-of-day timecode, the take number, each mic's name and a marker at every slate.
Does it record timecode?
Every file is stamped with time-of-day timecode from the phone's clock, at the frame rate you choose. Reading the DJI Mic 3's own timecode is being tested; the transmitters' backup recordings carry the DJI's timecode either way.
Does it work on iPad?
Yes, on any iPad with a USB-C port. The iPad gets its own layout, with tall meters on one side and the time and the record button on the other.
Can it change the DJI Mic 3's settings or start the transmitters' own recording?
Not yet. DJI only lets its own DJI Mimo app and the receiver's screen change the Mic 3's settings. CamPlot Recorder shows a checklist of what to set on the receiver (Quadraphonic mode, backup recording on every transmitter, timecode) and a button to open DJI Mimo. Other brands work the same way.
Which other mics and recorders work?
Anything that sends separate channels over USB-C: the Hollyland Lark M3, Zoom H6essential, H8 and M4, Tascam Portacapture X8 and X6 and MOTU interfaces in USB audio mode. Two-channel systems like the RØDE Wireless PRO, Sennheiser Profile and DJI Mic 2 record both tracks.
Does it work with the Hollyland Lark M3 or other 4-channel receivers?
CamPlot Recorder records every channel a USB-C device sends, each as its own track, so a receiver or recorder that sends four separate channels to a phone gets four tracks. It is tested with the DJI Mic 3 in Quadraphonic mode; the Hollyland Lark M3, the Sony ECM-W5 and recorders like the Zoom H6essential are supported in beta.
How is it different from recording audio in a camera app?
Camera apps record sound alongside a video file. CamPlot Recorder is audio only: no video eating the storage, every mic on its own named track, a slate marker you can sync to in the edit, timecode in every file, and it keeps recording with the screen locked and the phone in a pocket.
Does it work on Android or on a Mac?
No. CamPlot Recorder is for iPhone and iPad with a USB-C port. CamPlot's other apps run on the web, Mac and Android.
How do I get it, and what does it cost?
It's coming soon to the App Store as a free download for iPhone and iPad. Recording is included with CamPlot Plus and CamPlot Max: start a free trial in the app, or sign in with the CamPlot account you already use for CamPlot Creator, the Viewfinder or the Calculators.
