Audio level on cameras often have an adjustment for compressing the sound that is too loud so it doesn't clip. But then the dynamic range is limited. So if you want a high dynamic range, then the 32 bit float is the way to go. But as you say, for most situations, the compressing of loud sounds is perfectly acceptable. Perhaps it's a good comparison to D Log video which requires extra work in post and for most people is not needed. I'm glad this camera has both for those times when it matters, even if that's 1% of the time.

Thanks for the informative video. I'm not a sound expert. I'm listening to the sound comparison with a set of earphones. I couldn't hear any clipping on the 16bit audio. At least I couldn't hear any electronic high pitch sound as a result of the clipping.

Dude I literally just made a video about this, and this pops up on my feed the next minute. I've capped out the mics many times while screaming, it seems like the hardware has a limitation that bottlenecks the 32 bit float anyways.

is the soud from DJI so bad as you be talking to some metal can or did you set something wrong... or did you changed the mic you use during the video?

Good job. I'm interested in this camera, and I've watched a bunch of reviews. Most of them parrot the 32-bit float capability, but this is the first time that I've seen anyone explain it in a logical way. The mic 2 looks good from a convenience point of view, but 32-bit float is basically marketing hype.

It’s not hype, it makes the recording unclippable and you won’t need a back up track. Audio engineers will you don’t need it but a lot of people say you don’t 422 10-bit on a camera, or 32 gbs of ram in a computer, or remote start in a car. And you don’t, but it makes life easier. 32-bit is the same, you can just press record, not dial in settings, and fix it in post

I prefer the term "overhyped". I think that there are some users who will be able to get the benefit from it, but as I said in the video, for most users, it's a lot of work for little (if any) improvement. Thanks for watching and joining the conversation.

Did you have noise canceling turned on? The audio had annoying artifacts that sort of garbled the high end.

No. I made sure to turn it off.

@@AlbertStewart Yeah maybe he wanted to take out some ambient room noise and he set it to 100% in post. A little computer fan noise is better than noise reduction artifacts.

So 32 bit only works if you manually match up the audio.. and on top of that not forget to press record also on your mic..? And if I understand correctly this 32 bit doesnt work if you record on your phone and use a simple editing app like inshot or capcut right? So its better to turn it off then? Or does it not even matter?

Yes, it’s a lot of work for little gain (if any)

Not a bad video, at all. You forgot the sign bit, to indicate positive and negative values. The exponent is called the mantissa. I have never seen how many bits are used by DJI for it. Nor if the other manufacturers use the same number of bits. The remainder of the 32 bits are a binary fraction, to be used with the mantissa and sign bit to record the value of a single digital sample of the audio input. You correctly pointed out that 32 bit float usage involves extra work. And, it might not be worth it! Or, it might be, to some of us, sometimes, as a safety net for those unexpected wide dynamic range events. When you did the 32 vs 16 bit tests, something was wrong with the audio I listened to. Made the comparison useless. Audio was noticeably inferior to the preceding video. Finally, I find the transition you favour and use to be annoying. A simpler one would be fine. When you did the
