I have been back and forth via DM and it just appears to be a translation issue / talking to a brick wall. They don't acknowledge the technical details of what I am trying to say and just came back with "so it only happens when driving?"

Mega face palm. I need to start looking into how to return this thing, even though its past the 30 days with best buy and get something else. This is just not going to work, even though they claim it supports an external USB c microphone.

Mega disappointing. I was so excited for this camera over the gorpo. Oh well.

I think DJI can simply increase the negative gain to -32 or -48 and it will do the thing, Is it that hard for them?

If you read the entire thread, you can see that this would not work. You could do - 1million reduction and it would still have the hard cut of peaking issue.

Can we connect h1n directly with OA3? And make it record audio through h1n when we press record in OA3, I ll keep h1n connected to powerbank? Is there any way?

Is this with an EXTERNAL microphone? or the microphone built in the camera.

Hi, I just registered to comment to your excellent analysis.
I can confirm the same behaviour with a different adapter (USB-C to TRRS with own DAC) and an external microphone (Pixel M80).
This also happens with a Zoom H1 connected as external audio device when brought to clipping.

So, I am afraid that the clipping happens in the external DAC already. The Action 3 seems just to take the audio from the external DAC as it is. Gain Control can then just modify that (clipped) digital data, hence the clipping is still existent in the dampened audio.

I don't know if it is even possible to control such a simple external sound device (an active USB-C to 3,5mm converter is just that) via USB-C. I doubt, these small adapters can be controlled with software commands, but I don't know for shure - and I don't want to examine the possibilites of USB-C audio that far. ;)

If it is possible to control the input gain of the external DAC with software commands, a firmware update could fix the issue. But as I see it, the best (and maybe only) way for DJI to fix this issue, were to provide a dedicated USB-C to audio adapter - either controllable from the camera menu or with an own gain dial - best with auto gain possibilities. Put it in a small casing just like the 3rd party adapters for the Action 1 with some support in the opening to prevent force on the connector and moisture would be a no brainer for many people I think.

Another finding from my short tests - I can record very loud audio without any clipping when I use the H1 as audio device and adjust gain on that (or use Auto Gain, but that is not the best working festure of the H1...). And I can even connect any microphone with 3,5mm stereo jack and adjust input gain before it gets handed over to the Action 3. .Same should be possible with an active USB-C microphone, but I don't have one to check.

Gain control as it is now implemented in the Action 3 is just plain useless as it just seems to lower or rise the raw digital data.

Exactly!
I have tested with over 7 different setups, its exactly the same behavior with each one of them.
So, like I had said, in the main thread start itself, OSMO ACTION 3 audio is buggy for external source, and they need to fix it without any delay!!!

I think, it's not that easy. If my apprehension with noncontrollable USB-C devicess is correct, it's mainly an issue of the external DACs and  first of all that is out of DJIs reach.
The main problem is, that DJI decided to use USB-C audio input via active external devices without providing a dedicated one by themselves. Suitable controllable adapters are not easy to find (if there are any), so it's DJI's turn to fill that gap.
If they have nothing in the pipeline already, I think a fix would be nothing that could be done anytime soon.
So let's hope, there is a way to control external DACs by software or DJI is already working on a hardware adapter.
The only alternative i can think of is a dedicated USB-C microphone with its own gain control...
-edit-
A quick reminder for DJI-team members - a more comprehensive and transparent technical description for the camera features and accessories would be _very_ appreciated. It's a hard time to do research for all the quirks and issues that only arise because there is NO information, what really fits the camera's specifications. It's nice that some experienced users provide a lot of hints to their findings, that they only figuered out by trial and error. That is completely avoidable, if there were a good customer support.

Which adapter? Which Mic? Has the external mic a dedicated gain control?

bestbuy aluratek wireless mic usb type C

bestbuy aluratek wireless mic usb type C

Ah, very interesting. As is has automatic noise reduction it may also have automatic gain control. That is not the dumb USB-C to 3,5mm adapter, I was talking about.
I think, something like this is exactly what I am looking for, but maybe better with a universal transmitter to connect my own mic for more versatility.
The Rode Wireless Go II seems to be my object of desire. -edit-
No - its's not. ;)

The Rode wireless go I love,  I need to  get a USB type C/3.5mm adapter, not all work.  I am happy the one I got does the job for me, it may not for others,  I needed to spend  reward points and did good

Even DJI's own mic has a gain control on the transmitter, a gain control on the receiver and the OA3 has a gain (input volume) control, doesn't that tell you something?

Then why does my 10 year old GoPro4 with USB mic (no adapter, no dac, straight in to the unit) work perfectly fine with the GoPros automatic Gain?

Obviously GoPro went the other way for the Gopro4. You can transmit anlogue audio via USB-C or you can connect a digital audio device that processes the signal and transmits the results as digital data.
Analogue audio can simply be controlled by an internal DAC, so gain control, limiting and processing is managed there. The GoPro4 seems to have one and uses analogue audio signals, that can be dampened before processing to avoid clipping (just another guess).
The DJI Action 3 obviously does not have a DAC (USB-C adapters without DAC don't work) and relies on an external one, same as GoPro from the GoPro5 upwards, hence the MediaMod or their dedicated USB-C Adapter.
So the conversion is done in the external device. As I said, I don't know for shure, if it is possible to control a simple external sound device via USB-C without drivers - an embedded system like an action cam could only use standardized commands.

If the Action 3 can only process the already digitized signal from the DAC, clipping that has already happened cannot be fixed afterwards.
You can boost a signal, that is too low, though, so positive gain makes sense, even if you amplify background noise that way.

That's why DJI should offer something like GoPro does. A dedicated USB-C audio-adapter could easily be designed to be controlled by the internal controls of the camera or could even provide automatic gain optionally.

But they have something. The DJI Mics seems to offer just that. They are just a bit pricey if you don't need a wireless transmitter...

And don't forget - this is a lucky guess as DJI simply does not provide that info...

We simply need DJI to comment on this, if this is something can get fixed or not. We do not know the limitations of their hardware / firmware / software. It was advertised that a simple USB -C microphone will work, but it looks like for many of us that is not the case.

I am now out of the window of my store return with bestbuy, so I am not sure what I am going to do. For my purpose, this is now just a giant paper weight and a waste of 700 CAD.

Bumping this to keep it at the top.

DJI, any updates? Any confirmation of the issue, so we know that you know about it?

soamjena Posted at 1-22 00:30
I have tried with 4 lav mics so far :

BOYA

Filming easy, good audio, hard. Well. Money spend on good mic, ant no waist. But im seeking too. I'm looking for a trrs usbc there can Cornett. Have one, but, do not connect instant. But it do kind of, take the top of that pitch, and wind. So now, am waiting on my next trrs lol thinking, maybe buy samsung trrs usb.
My boya-k4 sucks. So, maybe try that samsung. They do make great stuff.

Thanks for the footage and Here is some updates:
the distorted audio happens because the audio signal has been too loud when coming from the 3rd party adapter. the digital gain of the current action3 setting is unable to tune down the already exploded audio.

we tested numbers of adpater reported audio issue,  majority of them can be altered to suit the moto vlog scenarios but some of them ignore the standard setting command from our developing firmware.

So whether a firmware update can solve the distorted audio with external mic, the answer is yes.

The issue is the volume number setting differs greatly for each adapter, we are still working on a strategy to suit as many as possible adapters that can be altered by the firwmare cmd.

So you are saying that BOYA BY K4 and many other adapters boost the sound?

so is ther actually a resistor on them?

Great to hear.
So at least there is a way to control an external sound device with commands. Because - it does not do that with the current firmware but just alters the amplitude of the recorded material.

Gain control has to be applied before analogue-digital conversion, not afterwards.
That, and the right mic for the right task should fix the issue ("don't use a vocal mic to record bass drums...")

-edit-
and I need a keyboard that doesn't bounce...

Maybe you should try a new firmware that enable RockSteady on your keyboard?

But serious get a big gaming mousepad that fit under your keyboard also, 1 meter in length or something.

Yep just get  a  film crew and be done

They built for common digital camera scenario, say vlog.

Just not for the moto.
