How to Record Audio from Your Cockpit — A GA Pilot’s Complete Guide

Recording cockpit audio is one of those things every GA pilot intends to do but most never actually set up properly. You land, the moment is gone, and the only record is a logbook entry and a blurry GoPro clip with wind noise. This guide covers every realistic option, what each one actually captures, and the cleanest way to get it done with minimal gear.


What does cockpit audio include?

Cockpit audio in a GA aircraft means four things happening simultaneously on your headset:

  • ATC transmissions — approach, departure, tower, ground
  • Intercom — your own voice, your CFI, passengers on the intercom system
  • Sidetone — your own transmissions played back as you speak
  • Ambient sound — engine, wind, avionics beeps (filtered but present)

All of it arrives at your ears through the headset. Any method that taps the headset or intercom signal gets all four. Any method that uses an external microphone in the cockpit gets only what a mic can pick up in a noisy environment — which in practice means poor ATC intelligibility and heavy engine masking.


Why cockpit audio recording matters

According to pilots we’ve spoken with, the most common reasons for wanting a recording are:

  1. Training and debrief — going back to hear exactly what ATC said, what the CFI said on final, where the readbacks went wrong
  2. Memory — first solo, first solo cross-country, instrument checkride, first night landing
  3. Content creation — YouTube flight videos, Instagram Reels, TikTok — clean audio is what separates watchable content from content people skip after three seconds
  4. Safety review — IFR pilots reviewing complex clearances, non-standard phraseology, their own decision-making out loud

None of these use cases are niche. They apply to almost every pilot flying GA today.


Method 1: External microphone in the cockpit

This is the most common attempt and the least effective.

Pilots mount a GoPro on the dash or glare shield and rely on the camera’s built-in mic. The result is typically:

  • Heavy engine noise masking speech
  • Wind noise from vents and door seals
  • ATC barely audible or completely unintelligible
  • Intercom completely absent (the intercom signal never reaches open air)

Some pilots try positioning a separate USB mic near the panel. This improves ambient quality slightly but doesn’t solve the fundamental problem: the intercom system is a closed electrical circuit. The audio on your headset does not exist as acoustic energy in the cockpit — it exists only as an electrical signal delivered to your ear cups. A microphone in the cockpit cannot capture it.

Verdict: Works for engine and ambient sound. Fails for ATC and intercom.


Method 2: Recording directly from the intercom system

This is the correct approach.

GA intercoms output audio through standard PJ plugs (PJ-068 for mic, PJ-055 for audio — the twin-plug standard you see on every GA headset). The electrical signal present at the audio plug carries everything: ATC, intercom, sidetone.

Tapping that signal and routing it to a recording device captures the full cockpit audio environment in clean analog quality — no noise floor issues, no engine masking, no compression.

There are a few ways to accomplish this:

Using a dedicated splitter cable

A passive splitter cable sits between your headset and the intercom panel. It passes the signal through to your headset as normal, while simultaneously routing a copy to a recording device via a second output — typically USB-C for modern smartphones or action cameras.

This is the approach the Cockpit Audio Recorder from Sigurd Aviation uses. Plug it in between your headset and the intercom, connect your phone via USB-C, open any recording app, press record. There is no app to install, no configuration, no power required. The cable is passive.

Verdict: Studio-clean audio, all sources captured, plug-and-play.

Using a dedicated aviation audio recorder

Devices like the FlightCast recorder work on the same principle but add onboard memory, a proprietary app, and typically a higher price point. Useful if you want the recording independent of your phone. In our experience, most pilots already have a phone in the cockpit and prefer to keep things in one place.

Using a mixer or audio interface

Possible but overkill for most GA pilots. Adds weight, complexity, and cost. Useful for professional content creators who want multi-track post-processing.


Method 3: Using your phone directly

If your phone has a USB-C port (or Lightning for older iPhones), you’re already set.

Modern smartphones automatically recognize an external audio input on USB-C. When you connect a properly wired cockpit audio cable to your phone, the phone treats it as an external microphone. Open Voice Memos (iPhone) or any recording app on Android, and recording begins immediately.

No driver installation. No app purchase. No Bluetooth latency. Just a cable.


What equipment do you need?

For the cleanest, simplest cockpit audio setup in 2026:

What you needWhy
Splitter cable with PJ-plug input and USB-C outputTaps the intercom signal, routes to phone
Smartphone with USB-C (or Lightning adapter for iPhone 14 and older)Recording device
Any recording appVoice Memos, Easy Voice Recorder, RecForge, GoPro app

That’s it. No batteries, no dedicated recorder, no app subscription.

The Cockpit Audio Recorder is 799 SEK (around 80 EUR) with free shipping in Europe. If you’re on iPhone 14 or older, the Lightning adapter version is 849 SEK.


Step-by-step: setting up cockpit audio recording for the first time

  1. Connect the cable — plug the PJ-plug end into your intercom’s headset jack (the same jack your headset uses). Connect your headset to the passthrough plug on the cable.
  2. Connect your phone — USB-C cable from the recorder to your phone’s USB-C port.
  3. Open your recording app — Voice Memos on iPhone works without any configuration. On Android, any app that shows external microphone input will work.
  4. Press record before engine start — you’ll capture the full flow from startup through shutdown.
  5. After landing — stop the recording, save it. The file is a standard audio file (typically M4A or WAV depending on your app).

First preflight, first time through, takes about 60 seconds to set up.


What headsets are compatible?

Any standard GA headset with a PJ-plug connection works:

  • David Clark H10 series
  • Bose A20
  • Lightspeed Zulu 3 / Sierra
  • Faro G2 / G3
  • Sennheiser S1
  • Pilot Communications USA
  • Any other headset with the standard dual PJ-plug

The PJ-plug standard (also called the standard GA plug) is universal in fixed-wing general aviation. It is not the same as the U-174 military plug used in most helicopters — helicopter pilots will need a different solution.


What aircraft are compatible?

Any GA aircraft with a standard intercom system using PJ-plug headset connections:

  • Cessna 150, 172, 182, 210
  • Piper Cherokee, Warrior, Archer, Arrow, Seneca
  • Diamond DA20, DA40, DA42
  • Cirrus SR20, SR22
  • Beechcraft Bonanza, Baron
  • Any aircraft with a Garmin GMA 340/345/350, PS Engineering PM1000/3000, or similar GA intercom

Not compatible: helicopters (U-174 plug standard), airliners (XLR intercom systems), aircraft with proprietary digital intercoms.


Recording quality: what to expect

In our testing, recording directly from the intercom produces results that are genuinely comparable to a recording studio environment — in the sense that the signal is clean, uncompressed, and free from acoustic noise. You hear exactly what enters the headset: ATC at full intelligibility, intercom at conversational clarity, your own voice in sidetone.

This is categorically different from ambient microphone recording, where intelligibility depends on mic placement, cabin noise, and the acoustic properties of a running engine in a 40-year-old airframe.


FAQ

Can I record cockpit audio legally? In most countries, recording cockpit audio for personal use (training, memory, content) is legal. Recording and then transmitting ATC communications is regulated separately — check your national aviation authority’s rules. In general, recording for personal use or training purposes is unproblematic. For content creation, standard practice is to avoid publishing raw ATC audio without context.

Do I need to tell passengers I’m recording? Consent rules vary by jurisdiction. In many countries, recording a conversation you are a participant in is legal without informing others. If in doubt, a simple “I’m recording this flight for training purposes” before engine start covers it in almost all jurisdictions.

Will recording affect my headset or intercom? No. A passive splitter cable draws no power and adds no load to the intercom circuit. Your headset functions identically.

Can I record and listen simultaneously? Yes. The signal is split passively — your headset receives the full signal as normal while a copy is routed to the recording device. There is no latency, no quality degradation on the headset side.

Does it work with noise-canceling headsets like the Bose A20? Yes. The recording taps the electrical intercom signal before the noise-canceling stage in the headset. The recording reflects what the intercom system sends, not what the headset’s ANR processing does to it. In practice, the recording sounds excellent.

What app should I use for recording? On iPhone, Voice Memos works out of the box. On Android, Easy Voice Recorder or RecForge II give you more format control. For GoPro integration, note that GoPro cameras require GoPro’s own USB-C to 3.5mm adapter — the USB-C audio signal standard used by phones is not the same as GoPro’s proprietary input.

How large are the audio files? A 1-hour flight recorded in Voice Memos at standard quality is roughly 50–80 MB. On most modern phones, storage is not a limiting factor.
