Audio taching flights on video

[tkranz]

I downloaded a helitach ap for my iPhone. Its seemed to work outdoors in the fall.

I recently tried it on a Youtube recording of one of my flights just out of curiosity. It seems to work on parts of the flight that are steady and close by.

I'd like to see if anyone else with a tach app can duplicate my results.

Tom's New Goblin 500 (5 min 21 sec)

I get 2408 to around 2420 indicated RPM on the app.

I was showing 2403 to 2448 RPMs using the HeliTach app on my iPhone.

I'm getting a reading of around 3,000rpm for the majority of that flight. There's a lot of movement in that video though, and not much time with the heli just hovering nearby.

For me the spectrogram display is showing noise over a huge range of frequencies, without a clear peak most of the time.
