This video shows testing of the Osmo Pocket while using the audio adapter and an external homebuilt (DIY)  microphone based on the Primo EM-172 Mono Omni cartridge.  

The test was performed  with loud background noise provided for by a Corvette.  

The EM-172 microphone has a pop filter and a dead cat over the cartridge.  

The audio in this video was not processed in Post and represents the audio recorded by the Osmo Pocket.

Awesome car

Thank you DJI Stephen.

You are very much welcome BobWinNV. Have a safe and happy filming always.

Hi Bob.

The wind and air movement was basically none existent, very impressive.

The problem with when you are driving is that dynamics processing in the Pocket is over responding to the low end energy created by the car's engine. At the start and the end, without the engine, the dialogue is great and not being pushed down with the engine triggering the dynamics processing.

The overall tone sounds great, can't wait to hear other examples of your setup.

Cheers,
Dave.

Dave,
I will be posting more audio examples and also the microphone basic build.  Even with the wind and engine noise i think that a little post processing would make it quite nice.  I will run it through Loudmax and Audacity  to see what they can do with that audio.

Bob

Cool! Looks great!

Yes, the Osmo Pocket recorder and DIY EM-172 microphone did a good job under the circumstances.

This is the exact same thing I experienced in a recent test.  Using Auto without the low rumbling of accelerating was fine.  But then the Osmo really clamped down on the gain and messed things up

I had a 2008 Corvette in Black for a few years...  It was awesome!

Hi.

The problem is very low end frequencies which we as humans don't hear so well but feel. These LF frequencies tend to carry a lot of energy and travel very well, it's these energy levels that a microphone can be very sensitive to due to the differential in air pressure, which can also be interpreted as sound pressure level, SPL.
It's this difference in pressure with such high energy low frequencies via the microphone that the dynamics processing in the camera sees as an increase in level and tries to account for it by over limiting or compressing. The result being that other sounds are pulled down, such as Bob's voice. This is the same thing that you experienced.

The interior of a car can also trap a lot of sound/energy and make the effect way worse than what it really is.

Cheers,
Dave.
