So today i got my new verizon 32gb iphone and i just synced 27.1gb of music onto it (~4000 songs). This leaves hardly any room for apps, and no space for pictures or video, although i'm fine with that if i have my music. In the summary tab of the iphone syncing options in itunes, i noticed an option that says "convert higher bit rate songs to 128 kbps AAC". I know that this basically means dumbing down most of my songs' "quality", but to what extent? Right now, it says i have 0.46gb free space on my iphone. when i check this box, it changes to 11gb free space. WTF? what will this do if i click apply? will the songs be noticeably worse? how could this possibly get rid of 10.54gb? how bad is the compromise? Like i said, i'm sorta okay with having this tiny amount of memory free, but if this option won't make my music noticeably worse, i'd love to take advantage of it. Who has experience with this, or knows about sound quality/ bit rates? If it helps, i listen to music from my iphone either on a decent quality stereo with sub, or my skullcandy FMJ in-ear buds. Usually quite loud. Thank you for your help!
