The iPhone can be used as an everyday recording device to capture interviews on the go. However there’s a few things you need to do first.
US journalist Neal Augenstein says the iPhone comes close to broadcast quality, but you’ll still need to purchase a windshield or muffler like this to guard against plosive P sounds.
You could also purchase an external device such as the IK Multimedia’s iMic or Rode’s ME Reporter
Record using the Ferrite app or Voice Record Pro, where you can record in the .wav format (check settings) rather than Apple’s default codec.
Others on the station use a portable Zoom Recorder
For editing your content Audacity is great and free. Or the pro app Adobe Audition.
