How to Record Sound on Your Phone? Best Microphone for iPhone Video

Smartphone Built-in Mics Suck, But Why?

First, let us address the elephant in the room… “Why does the smartphone audio suck when everything else seems to be awesome and smart?”

The simple answer is that the designs of iPhones and Android phones are optimized for on-screen performances, such as visual capacity, app operations, and browsing - but not for voice quality. That’s a result of size – while other electronic components have reduced in size over the years, microphone recording still requires large physical components. As a result, built-in microphones are tiny and operate with a very restricted frequency range.

Additionally, most of these built-in microphones support mono recording, but not stereo. The devices usually use low-cut filters (AKA high pass filters) to suppress background noise – but that’s only good when you’re close to the sound that you want to record.

Newer models of iPhones and high-end Android phones are improving their sound recording abilities, but even so, the audio quality still can’t compete with external microphones when recording loud sounds, being used for in-field operations, etc. Even iPads can benefit from being used with iPad bluetooth microphones.

If you’re a vlogger, a musician, or simply want to make great videos with your smartphone, you can’t cut corners with audio quality. The good news is that there are plenty of external microphones available.

Phone Recording Tips

• The first thing I do before recording on my phone is to enable airplane mode, so the recording will not be interrupted by unexpected calls, text messages, etc.
• No matter which microphone you choose, be aware of the direction that you place the mic for the best sound. If you use a lavalier lapel mic, it means you will want to clip it close to your mouth or the sound source.
• Instead of speaking loudly, you’ll want to watch your sound levels, so it stays stable throughout the recording. There are a few free apps you could get, such as Decibel X and Decibel Sound Meter Pro, to help you with this.
• Check for wind and other noise sources.
• Post editing is as important as the recording
