Recording Great Audio with your Smartphone
Eli asks: I’m using a Samsung Galaxy and an iPhone for the first time to record some corporate videos. The sound quality is not that great. Any suggestions on making it better? Can I use an external microphone?
Answer: Audio is always a problem with Smartphones and even tablets. The mics are used mainly for phone conversations and less for video production. While most jacks do appear to welcome an external microphone with the standard mini-jack, most do not. They require whats called a 3.5mm 4 conductor TRRS jack. Because of this special adapter, an entire ecosystem of accessories has formed around overcoming the audio limitations of your phone.
