    Hey guys - I've been trying to figure out how to effectively record cockpit radio - I've used a splitter but no matter how much I lower or increase the volume in cockpit the audio redlines in the gopro. Has anyone else come across this issue?

    Not going to buy a dedicated recorder with an equalizer... just saying.

    ZackJ, Nice video and looks like she enjoyed the flight, well done!

    This video does not help with trying to figure out the audio problem and come up with corrective action. Can you clarify:

    1-The audio quality you are getting? Too loud, not loud enough, hum etc.

    2-What are you using to record? The built in mic on the GoPro or a patch cord to the audio input jack?

    3-How comfortable are you with simple electronics? Could you fabricate a splitter with an attenuator?

    Let's see if we can make it happen captain!

    Enjoyed the video! I had to laugh when your passenger blessed herself :)

    I have a cable for my Garmin VIRB that I use to record the audio right to the camera. Not familiar with GoPro, maybe they have such a cable. Is there an adjustment on audio level in the GoPro settings?

    When you edit, adjust the audio file. Both software packages I use can easily change the audio levels and or mute sections you select. I use Wondershare (free) and Movavi.

    Never had a problem with gopro hero 5 + the ridiculous $50 gopro audio adapter + nflightcam cable (the correct cable). Here is a link:

    https://www.amazon.com/Nflightcam-A...coding=UTF8&psc=1&refRID=60D3ZA8V8VC160PD9HMG

    ...it sounds like you are trying to use a standard splitter cable and that won't work. Also, if you have all this and it doesn't work you might have a incorrect audio setting on the gopro...I think there are like 2 or 2 options (stereo, wind, auto) so mess with them.

    In my setup I can just plug the gopro into a TV with the HDMI cable and watch the video and the sound doesn't need any editing...the levels are correct. This even goes for the camera outside on the wing or the one mounted inside recording audio as if no headset on.

    Just my mic is too loud - ATC audio is perfect. I’m using a direct cord from the GoPro to the jack output for the headset.
    I’m currently using a splitter - but I didn’t know about the attenuator.
    That sounds like a good idea - the only thing is it would also affect the ATC radio volume which is currently perfect.

    I have a GoPro knockoff with no mic input so I have always used a separate audio recorder, so take this with the proverbial grain.

    But, other than an attenuator, have you tried a mic in you headset earcup instead of in the headphone splitter? A lot of folks have had success with that. I've done both and, depending on the airplane, have had good results with one or the other.

    Like a support call:

    What splitter (is it specifically for aviation - if not start here?)
    What headsets are being used?
    What audio panel?
    Are your headset volumes turned way down and you are compensating by turning up the intercom volume?
    Which gopro?
    Which gopro audio adapter?

    If there is nothing weird/non-standard up above then you might want to just sit in the plane with the master on and field ATIS running and then do the following:

    Start the gopro recording:
    Set headsets around 40%
    Bring up the ATIS until you like it, each time you just record what you did via the mic
    Bring up the intercom volume until you like it and each time record what you did via the mic.
    Maybe you'll find a better combo.

    Our KMA intercom volume is knob is probably set at 1/3. Our first KX155 is probably set at 40%. Our second KX155 (usually for ATIS) is set about 25%. I think the headphones are usually set around 40%-60%. I have the GTX345 audio callouts set to about 75 in the setup panel to hear the callouts.

    Hmm kind of clutching at straws here but talk to your avionics person. Maybe the audio output from the intercom or the sidetone level can be adjusted? Good luck!
