When I told some friends that I was “podcasting” on iOS, they assumed that all I was doing was recording myself on iOS and doing the post-production later on a Mac. Not so! In fact, we actually do the entire end-to-end audio production purely on iOS.
Fraser Speirs details his workflow for producing episodes of Out of School without a Mac. The fact that several episodes have been created using an iPhone and iPad with a portable podcasting setup is pretty incredible.
Also of note (towards the end): one of the benefits of the A7 processor.
