Hi all, been lurking for a while and could use some help.

I am a General Aviation Pilot and would like to record cockpit audio. Its a standard 1/4 audio connector that goes to a pair of headphones (headset, same diff)

I have a 1/4 splitter + 1/8 adapter, male-male patch cable and the official gopro mic adapter cable.

All I get is a digital sounding signal that is in no way clear.


This is Exactly what I have done except with the genuine mic cable. (see 1:40 )

I have also tried plugging it in directly to my iphone to record music with my video, and no luck there either.


THEN I found this site about how to make an attenuator with resistors and that just made the digital sounding noise quiet.

There has to be someone who has done this before. Please share your wisdom!

If anyone is interested....

you-tube this: Headphone Output/STEREO MIX To MIC Input For Recording

Basically you need the following added to a male-male patch cable for each channel.
1/4w 330ohm metal film resistor
1mf tantalum capacitor (electrolytic will work but size is an issue.)

Allows you to connect ipod/mp3 player to MIC INPUT on GoPro
