How to record intercom audio and pace notes on your GoPro

5 hours ago

1 min read

The GoPro's own microphone can't hear your co-driver. Under helmets, with engine and gravel noise, the pace notes are lost. If you want to review calls, check your co-driver's timing or share proper onboards, you need the intercom audio recorded straight into the footage.

How it works

A cable runs from your intercom's camera or recording output to the GoPro. Everything said over the intercom (pace notes, calls, the shout at the finish) is recorded on the video's soundtrack, perfectly in sync.

Which intercoms work?

Stilo, Peltor, Zero Noise, Terratrip and other leading rally intercoms. Not sure about yours? Message Tom before ordering.

Getting clean audio

Set the intercom's camera output level. Too low and the notes are faint; too high and they distort. Do a short test recording and adjust.
Route the audio cable away from power wiring. Running it alongside 12V or ignition looms can pick up hiss and whine.
On 12V power, use a noise-suppressed cable. Cars are electrically noisy. All our intercom kits are noise-suppressed for cameras running on the car's 12V.
Test with the engine running. Some noise only shows up then.

Do it once, with the rest of the kit

Intercom audio works best as part of a complete setup: one button to record, LED confirmation, 12V power and audio, all fitted together.
