What does it mean when iTunes says "Convert higher bit rate songs to 128 kbps ACC"?

I want to just know what this signifies Does the idea mean ‘Better’ or ‘Worse’

It converts top quality songs on the standard quality so they do not persue as much space on your own ipod

That means a lower top quality, but unless you will be enjoying the audio at very good volumes (like an individual DJ by way of your ipod) then that may be fine.

If you might have lots associated with songs and never much space this is a good idea, if you have lots associated with space then i might suggest leaving behind them as they quite simply are:)

128kbps will be quality, songs which can be higher than that age.g 320kbps are higher quality thus use up more place.So whenever it claims covert this it means lower the coffee quality to help you fit far more on yor mp3 and acc is probably a track type:).
