What's the difference between audio file formats?

Last week we talked about the differences between Video Codecs, and more specifically about the advantages and disadvantages between ALL-I and IPB.

Audio File Formats

Since last week’s post I’ve received several questions about audio formats. Instead of rewriting what has been already done well, I’ll direct you to an article by Izotope, which is in my humble opinion the provider of best audio plugins in the market.

The article covers the differences between wav, aiff, mp3, and m4a, which is pretty much all we need to know as filmmakers.

Audio Gear

Lots of folks have also been asking about “the most minimalist audio kit” I’d suggest.

Here it is: a wireless system, an audio field recorder, and extra mic that can doble as on-camera shotgun mic or boom mic, a couple of XLR cables (always bring backup cables), and enough rechargeable batteries to have a fully charged backup at all times. The H4n Pro is specially power hungry, so I’d strongly suggest getting the kit with the AC adapter.

I added one more item that is nice to have, but nor essential; the Rycote Undercovers, which allow you to “stick” a lavalier mic to a subject over or under their clothes. Much more useful than you would think.
