Audio
Bad audio quality is something that you and your listeners can quickly detect and be frustrated about. Not only is it hard to listen to, but it’s hard to understand what is being said.
What should you do? Well, you don’t have to buy thousands of dollars of gear or book a recording studio to have great sound. It’s easy to capture great audio from your phone by simply tweaking a few key settings, changing how you record, and for the best results: invest in a portable microphone.
Tweak your recording settings:
Put your phone on airplane mode and mute your notifications.
By putting your phone in airplane mode, you prevent phone calls and text messages from interrupting your recordings. Also, most phones have a “Do not disturb” feature, this will prevent notifications and vibrations from interrupting your audio recording.
iPhone (iOS): Voice Memo app (included with your iPhone)
Improve the audio quality by recording in lossless format (which is a non-compressed audio file). You can easily do this by going to Settings > Voice Memos > Audio Quality and choosing “Lossless.”
iPhone (iOS): Voice Record Pro app (free with ads or ad-free for 7£ GDP)
Voice Record Pro is a more powerful version of the built in Voice Memos app. You can control the gain, sample rate, bit rate, and encode quality. You’ll need to use trial and error to see what settings will suit the environment that you are recording in. Try a short test recording and re-listen to it with headphones to see what settings decrease the environmental distortion and sounds clearest.
Android: Titanium Recorder (free with ads)
Titanium Recorder is a powerful voice recorder. Tap the menu button (it has three dots in the top right of the screen) and choose Settings. Here, like in Voice Record Pro, you can adjust the sample rate, bit rate, and gain to make sure that your audio recording is clear in the environment that you are recording in. Just like above, try a short test recording and re-listen to your recording with headphones and change the settings as necessary.
Ensure that your microphones are not covered or obstructed.
First, find where your phone’s microphones are located. They are usually at the bottom of the smartphone because that’s where you’d speak into if you were making a phone call. They could also be by the camera(s). Just make sure that when you are recording, you don’t have a case or your finger covering these microphones. By uncovering your microphones, you will prevent your recording from sounding muffled or garbled.
Point your microphones towards your main speaker.
Most phone microphones are directional and if your microphones are pointed away from the main speaker, it relies on the echos or reverberations of the speaker’s voice off of the wall or table. These echos are really hard to decipher and cause the audio quality to be very poor.
For big rooms, bring the microphone closer to the speaker.
If you are recording in a conference room and want to better transcribe your meeting minutes, pass the phone around from speaker to speaker. Having the microphone closer to the speaker will make the audio sound much better. Also, if you are recording a lecture or a speech, sit in the front row if possible; do not try to record from ten rows back.
Portable microphones you should consider:
An external microphone will give you the best audio quality.
By supercharging your phone with an external microphone, you will ensure that you have the best recordings. However, it’s a challenge to choose which microphones will work best with your phone. iPhones require the microphones to have a Lightning connector, while Android phones require the microphones to have a USB-C connector.

One final thought:
By having high quality audio recordings will also benefit your listeners who have a higher likelihood to stay better engaged with your content. If you only were to do one thing as a result of reading this article, we would highly suggest that you add a portable microphone.
