Googled the above topic and it seems like M2P has no way to record audio and yet I keep seeing more videos posted here where there were audio channels blended into the vids.

Do they record those audio separately elsewhere and blend into the vids in software ?

Please enlighten.  Thanks!

It does record audio on the cached video (which stays in your mobile device, not on the microSD).
That said, in order to retrieve the Video with the audio (always recorded from your smartphone, never from the aircraft itself since it doesn't have a microphone), you need to Go to the little Playback icon on the bottom right, select the video, select Cache on the top right and them download it.

Videos downloaded from the SD card (or called Original on the DJI Go 4 app gallery) never have audio since they are the pure video recorded directly on the aircraft.

Be advised that the cached video will record any signal interferences, image "blocks" and any other noise since it is a muxed result from the aircraft stream with the recorded audio from the smartphone, thus it carries all the noise from the tx/rx between the AC and RC and can reach maximum 1080p.

Thanks.

I understand that it had to be a separate audio channel that needs to be blended into the vid during post-editing.

Can anyone recommend the best portable device to record my own audio separately?

Hi, thanks for the inquiry. You could be able to produce an audio on your cache file recording, however, the sounds were produced by your mobile device and can't be obtained on your SD card file. You have to enable the cache option on your DJI GO 4 app. Please see the image below for your reference. Thank you for the support.
