So do you need more proof that mobile devices are becoming more powerful by the minute?
I just learned of a band, One Like Son, that has recorded it's entire album on an iPhone. You read that right, using adaptors for their instruments and a few apps on the iPhone, this band has skipped using a recording studio and produced an excellent sounding album on nothing more then an iPhone.
Being a wannabe rockstar myself, I have toyed around with Garage Band on my iPad, and even recorded a few things. I have never heard of an entire album being recorded this way though. If I hadn't told you it was recorded on an iPhone you'd never know.
