When it comes to recording video with your cell phone, the quality of the audio can often be just as important as the visual aspect.
However, achieving professional-sounding audio can be a challenge when using a device that wasn't specifically designed for audio recording. The built-in microphone on most cell phones is designed for voice calls, not for recording high-quality audio. Fortunately, there are a few simple tips you can follow to improve the audio quality of your mobile video recordings.
Use an external microphone
The built-in microphone on most cell phones is designed for voice calls, not for recording high-quality audio. To achieve a professional sound, consider using an external microphone. There are several different types available, including lavalier (clip-on), directional (shotgun), and omnidirectional (memo) mics. Each type of microphone has its own specific use cases and advantages.
Lavalier microphones, also known as lapel microphones, are small, clip-on microphones that can be attached to clothing. They are great for recording interviews or speeches in a noisy environment. Directional microphones, also known as shotgun microphones, are long and narrow, and are designed to focus on a specific sound source while rejecting background noise. Omnidirectional microphones, also known as memo microphones, pick up sound from all directions and are great for recording live music or nature sounds.
Keep your phone close to the sound source
For best results, keep your phone as close as possible to the sound source, whether it's a person speaking, a musician playing an instrument, or a bird singing. The closer the microphone is to the sound source, the better the audio will be. This is particularly important when using a directional microphone, as it will help to minimize background noise and focus on the main sound source.
Avoid using the built-in microphone
If you can't use an external microphone, use the microphone on a pair of earbuds or headphones. Try to position any microphone as close to the sound source as possible. The built-in microphone on most cell phones is not designed for recording high-quality audio and will likely produce a poor-quality recording.
(Edit: Newer phones are increasing the focus on audio quality of the internal microphones so make sure to test which sounds better on your device)
Use a pop filter
A pop filter is a simple device that attaches to your microphone and helps to reduce the harsh "p" and "b" sounds caused by speaking too close to the microphone. These sounds can be especially problematic when recording voiceovers. Pop filters are inexpensive and can be purchased online or at a music store.
Record in a quiet environment
Finally, try to record in as quiet an environment as possible. Background noise, such as traffic or wind, can greatly affect the audio quality. When filming indoor, close the windows and doors to minimize outside noise and make sure to position the camera away from any source of noise in the room.
By following these tips, you can improve the audio quality of your mobile video recordings and achieve a more professional sound. Remember to experiment with different microphone types and positioning to find the best results for your specific recording scenario. With a little bit of effort, you can take your mobile video recordings to the next level and impress your audience with high-quality audio.
