[Shallowed]

What the hell, then further down it says this:

Switch can convert numerous audio file formats to mp3 and wav for free

...

Converts a variety of audio file formats to mp3 or wav such as: wav, mp3, mp2, mpga, m4a, ogg, avi, mid, flac, aac, wma, dct, au, aiff, ogg, raw, msv, dvf, vox, cda, atrac, gsm, dss, sri, shn, dss, msv, wmv.

So which is it?

Either way, Switch won't be able to convert ac3 to anything.
