Yes, GoPro cameras record audio by default, but the quality and what you capture depends on which model you own and how you position the camera
Every current GoPro model has a built-in microphone and records sound automatically when you press record. The microphone sits on the camera body itself, so audio quality depends on where you point the camera, how far you are from what you want to hear, and wind conditions. A GoPro pointed at your face while you talk will pick up your voice clearly. A GoPro mounted on a helmet while you ride a motorcycle will record mostly wind noise unless you add an external microphone.
The audio file saves inside the same video file as your footage—you do not need to do anything extra to capture it. When you play back the video on your phone or computer, you hear both the video and the sound together. If you do not want audio, you can turn recording off in the camera settings, though most people leave it on and delete the sound later if they do not need it.
Key Takeaways
- All GoPro models record audio automatically through a built-in microphone when you press the record button.
- Built-in microphone audio quality is good for voices and nearby sounds but picks up heavy wind noise on fast-moving activities.
- You can disable audio recording in the camera settings if you want video-only files.
- External microphones designed for GoPro cameras can replace or supplement the built-in mic and reduce wind noise significantly.
- Audio files are embedded in the video file itself, so you cannot separate them without editing software.
How the built-in microphone performs in different situations
The built-in microphone works well for stationary or slow-moving shots where you are close to the sound source. If you are vlogging and holding the camera at arm's length, your voice comes through clearly. If you are recording a conversation at a table, both people sound natural. The microphone is sensitive enough to pick up ambient sound—birds, traffic, water—without you having to do anything special.
Wind noise is the biggest limitation. When the camera moves fast through air—on a bike, in a car, while running—wind hits the microphone and creates a loud rushing sound that drowns out everything else. This is not a flaw in GoPro; it is physics. Any small microphone exposed to wind will struggle. Even expensive external mics need foam windscreens to handle this. If you are recording action sports or anything outdoors in wind, expect the audio to be difficult to use without editing.
Water and moisture can also affect the microphone. GoPro cameras are waterproof, but the microphone opening can collect water droplets that muffle sound. If you are filming underwater or in heavy rain, audio quality drops noticeably. Some people use waterproof external microphones for these situations, though many action sports videos straightforward accept poor audio and add music or voiceover in editing.
Turning audio recording on and off
Audio recording is turned on by default on all GoPro models. To disable it, open the camera settings, find the audio or sound menu, and toggle recording off. The exact menu name varies by model—some say "Audio," others say "Mic," and newer models may list it under "Capture Settings." Check your camera's manual or the GoPro app to find the exact path for your model.
Most people leave audio recording on even if they do not plan to use the sound, because it takes almost no extra storage space and you can always delete it later. Turning it off saves only a small amount of file size. The real reason to disable it is if you are recording in a situation where the microphone will pick up unwanted noise—for example, if the camera is mounted inside a helmet and you only want the video, not the sound of your breathing and helmet rustling.
External microphones and when to use them
GoPro sells official external microphones and supports third-party options. The most common external mic is the GoPro Wireless Mic System, which clips to your shirt and sends audio wirelessly to the camera. This solves the wind noise problem because the mic sits closer to your mouth, away from the rushing air. It is useful for vlogging, interviews, or any situation where you want clear voice audio.
Other external options include wired lavalier microphones that plug into the camera's USB port, and foam windscreens that fit over the built-in mic to reduce wind noise. Windscreens are cheap—usually under $15—and help noticeably on action footage. If you are serious about audio quality, a wireless mic system costs more but gives you professional-sounding voice recording.
External mics are optional. Most GoPro users never buy one and are happy with the built-in audio for casual videos. You only need an external mic if you are recording in windy conditions, need clear voice audio, or are filming content where sound quality matters as much as the video.
Audio quality across different GoPro models
Newer GoPro models have slightly better microphones than older ones, but the difference is small. A GoPro Hero 11 has a marginally better built-in mic than a Hero 9, but both will pick up wind noise in the same situations and both work well for voices and nearby sounds. The microphone hardware is not the main factor in audio quality—positioning and wind conditions matter much more.
All current models record audio in stereo, which means you get sound from the left and right sides of the camera. This creates a more natural, spacious sound compared to mono. When you play back the video, you hear this stereo effect if you use speakers or headphones.
Editing and removing audio after recording
Once you record video with audio, the sound is baked into the file. You cannot separate the audio from the video without using editing software. Programs like Adobe Premiere, Final Cut Pro, or free options like DaVinci Resolve let you mute the audio, replace it with music, or add voiceover on top. Most people do this in post-production—they record everything, then decide what to keep or change when they edit.
If you recorded a video and the audio is unusable because of wind noise, you have a few options: mute it and add music, record voiceover to explain what is happening, or re-record the audio separately and sync it to the video. None of these require you to re-film the video itself.
Frequently Asked Questions
Can I record video without audio on my GoPro?
Yes. Open the camera settings, find the audio or mic option, and toggle it off. This prevents the microphone from recording, so your video file will have no sound. Most people leave audio on and delete it later if they do not need it, since the file size difference is minimal.
Why does my GoPro audio sound like wind rushing?
The built-in microphone picks up wind noise when the camera moves fast through air. This happens on bikes, cars, and while running. A foam windscreen over the microphone helps, or you can use an external wireless microphone that sits closer to your mouth instead of on the camera.
Does GoPro audio work underwater?
The camera is waterproof, but the microphone opening can collect water droplets that muffle sound significantly. Underwater audio is usually poor quality. Many underwater videos are filmed with audio off, then music or voiceover is added during editing.
What external microphone works best with GoPro?
The GoPro Wireless Mic System is the official option and works reliably. Foam windscreens for the built-in mic are cheaper and help reduce wind noise. For budget options, some third-party lavalier mics work, but check compatibility with your specific GoPro model before buying.
Is GoPro audio good enough for vlogging?
Yes, if you hold the camera at arm's length and speak clearly. The built-in mic picks up voice well in calm conditions. For windy outdoor vlogging, a wireless external microphone gives noticeably better results and is worth the investment if you vlog regularly.
