Phone video looks sharp, but phone audio often sounds distant, echoey, or buried under traffic and wind. The fixes below start with the ones that cost nothing (distance, location, wind, and app settings), then cover when an external microphone is worth adding.
Distance is one of the biggest factors affecting phone audio. As your phone moves farther from the speaker, their voice becomes quieter while echoes and background sounds become more noticeable. If you are relying on your phone’s built-in microphone, position the phone as close to the speaker as your shot allows.
Pause and listen to your surroundings first. Common sources of unwanted noise include air conditioners, fans, appliances, traffic, nearby conversations, background music, and construction.
Whenever possible, turn off unnecessary equipment, close doors and windows, or move to a quieter area. Removing noise at the source sounds more natural than filtering it out later.
A quiet room can still sound poor if it has a lot of hard, uncovered surfaces. What most people call echo in a room is technically reverb: sound bouncing off hard surfaces and reaching the microphone a split second after your voice. Empty rooms, kitchens, hallways, and bathrooms reflect a lot of sound, which makes speech feel distant or hollow.
Rugs, curtains, couches, bedding, and other soft materials absorb sound, so a furnished room sounds less hollow than an empty one. If your recording sounds echoey, try moving to a furnished room or positioning yourself away from bare walls and corners.
You can also place soft materials outside the camera frame to reduce reflections. Even a thick blanket, curtain, or nearby couch can help.
Most phones have more than one microphone, placed in different spots around the body. Before recording:
Be especially careful when switching between portrait and landscape recording, since your grip and microphone position may change.
Wind is one of the most difficult audio problems to repair. When moving air hits a microphone capsule, it can create deep rumbling, crackling, or sudden bursts that cover the speaker’s voice.
Noise reduction in your recording app can lower steady background sounds, but it often cannot restore speech once strong wind has overwhelmed the microphone. Physical wind protection is much more effective.
If you are using an external microphone, attach a furry windscreen before recording outdoors. The fur breaks up and slows the moving air before it reaches the microphone capsule.
You can also use your surroundings for protection. Stand behind a wall, vehicle, building, or other windbreak, and position the speaker so their body helps shield the microphone from direct gusts.
Recording options vary between phones and apps, so review your settings before an important shoot. Check that:
Gain sets how loud the microphone signal is before it's recorded. Some apps set it automatically, often labeled AGC (Automatic Gain Control). If yours lets you set it manually, start in the middle and leave room for louder moments. Too much gain raises background noise along with your voice, and if your voice goes past the maximum level, it clips: the peaks are cut off, and that distortion can't be removed afterward.
Your phone’s built-in microphone may work well when you are nearby and recording in a controlled environment. It becomes more difficult to use when the phone needs to sit several feet away, the speaker is moving, or the location is noisy.
An external microphone lets you keep the mic close to the speaker while positioning the phone wherever you need it for the shot. A wired microphone can work for stationary setups, while a wireless microphone lets the speaker move freely.
When choosing a phone microphone, check:
Elgato Wave Go is a wireless microphone for phones and tablets with a USB-C port (Lightning iPhones aren’t supported). Plug the USB-C receiver into your phone, then clip the mic transmitter to your clothing for hands-free recording or slot it into the Smart Handle for interviews.
Onboard processing adjusts your levels and tone automatically, including EQ Shift, which tunes the sound for clip-on or handheld use. Two furry windscreens come in the box for outdoor shoots. You can adjust gain and noise cancellation in the Wave Go app (iOS and Android), but it’s optional.
The mic transmitter runs up to 8 hours per charge, and the Smart Handle recharges it when you’re away from an outlet. To record two people on one phone, add a second transmitter, which pairs with the same receiver.
Try the free fixes first, and listen back to a short test clip before every full take. If the phone still has to sit too far from the speaker, our Wave Go overview covers setup, battery life, and compatibility.
