The DJI mic does not transmit 32 bit float over the 2.4GHz wireless transmission. It can only transmit 24 bit int. This is like recording a 1080p wireless transmission of a video in RAW.
People keep saying this but I’ve actively recovered “clipped” audio from the 32bit DJI lav mic setup…if it’s not “true” 32bit or something, it’s still clearly better than the 24bit files using the same setup. I can do more testing but there’s nothing that would indicate the wireless transmission is a limiting factor.
DJI mic - Doing it this way as 32bit is pointless. The gain stage has already happened before it was sent wirelessly. 32bit float only works at the point that you first digitize the analaog audio pre amp. Thats why the DJI mic does 32 bit INTERNAL recording and not sending.
That does not seem to be the case from my testing so far. I have recovered “clipped” audio from the DJI mic using the 32bit recording. Hardly “pointless” as you say compared to the 24bit files
@@_tographersorry dude the DJI test is incorrect. The receiver on the Mic 2 can’t send 32 bit float over the cable to the XLR adapter. The only way to get 32 bit from the DJI Mic 2 is using the recording function on the transmitter itself. What you recovered the clipping in your DJI test, it was still clipping from the receiver, but it was slightly cleaned up. Try the same test using the transmitter to record and notice the massive difference. It will be cleaner. Your limitation will be the mic capsule on the DJI Mic (from a sound pressure / physics standpoint)
I saw it put like this recently. A gunshot is around 150dB. 240dB is enough to straight up kill you instantly. An atomic bomb is ~330dB. 32-bit float has 770dB of headroom.
Does the DJI wireless mic output in 32bit? Does it matter? Is there a difference between the DJI internal 32bit vs the xlr adapter 32 bit? What I’d really like to see is built in 2x 3.5mm 32bit, but would also pay for an adapter that had no xlr, and only 3.5mm x2 w/ 32 bit for all 4 channels.
It doesn’t matter. 32bit isn’t in the signal, it’s how the file is recorded. There shouldn’t be a difference between 32bit on different recorders but I can’t confirm that for sure.
The 32bit from the DJI mic works as expected when using my Sanken lav mic. I think I was just hitting the physical limits of the microphone hardware itself in this test. The podmic and the DJI pack mic being less suited for extremely loud noises.
I have the same setup but a Boya shotgun microphone instead, tried it at a music concert and using 32 bit float still got clipping. I'm not sure if I set up everything correctly but suspect it simply might be a limitation of the microphone, it was a black metal band
Yes, after this result, I think I’m going to do some additional tests outside the studio with my lav mic and shotgun mic, more likely the actual scenarios where you’d find those extreme decibels.
I would like a smaller Version of the XLR that only has the 3.5mm Input for one channel 32bit. It could be a small box on the hot shoe with a normal hot shoe on top.
Yeah...I shelled out a lot of $$ to upgrade from the GH6 to the GH7 for a few features and the promise of virtually no audio clipping using 32 bit audio recording sounded very appealing since I shoot content where there is a lot of screaming from time to time. Much to my disappointment...I am actually getting WORSE audio clipping with the GH7+XLR2 adapter with 32 bit enabled than I was with my GH6+XLR1 adapter at 24 bit! Something is not right and I'm about to call Panasonic to see if they can help out. But so far...BIG disappointment for me!

awsome
take love from bangladesh

@ my thoughts were that it was only transmitting 24bit from the tx > rx, and might be clipping there before even reaching the xlr adapter?

Yeah that rode microphone is clipping. Try a better mic.

That would be better but still wish the tech could be built right into the camera body.
Same, I would pay for a non-xlr version for ch 3/4 + 32bit.

Follow up and let me know what you discover!
hah what a cathartic test. Thanks for sharing.
XLR 2 it can be used S 5 M ii
there's a firmware update for the S5II that lets you use it but it will only be 24bit, it wont be 32bit on the S5II
