Ever wonder what that sponge-like thingy is that everyone seems to put on top of a microphone?
It’s called a “pop filter” and If you care about audio quality and you want to be great at what you do, get one. They really are necessary for anything voice related. It helps with sounds such as 'P' and 'B' called plosives. Plosives are extra air going onto the microphone causing a very annoying heavy breath sound.
Next time you’re near a karaoke machine pick up a microphone without a pop filter - - they just slide right off - - and try reciting: Peter Piper picked a peck of pickled peppers. Listen for the “puff’ sound with every letter “P.” We all do it. Another example is: Buy back blue baby blankets.
More to the point, events planned sea side - - - weddings being chief among them - - - almost always include video recording. And, one way or another, most such equipment offers some manner of audio capture facility. Next time you’re at the beach try recording a friend’s conversation with your iPhone or Android. You’ll be amazed at how little you will hear over the ambient noise of the wind and surf.
You’ll be hard-pressed to find an effective pop filter for a cell phone, but they do exist. If you really want to capture the genuine spirit of the sea side moment invest in audio equipment tailored to the recording environment.
