Advanced -> Convert Selection to XXX
You have to choose between WAV, AIFF and MP3 in preferences.
If you're going from 300+ to 160 and it's mp3 -> mp3 then you won't notice as much audio degredation as you woud from a lower bitrate and changing codecs. In fact I doubt you'd notice it at all.
To make sure you get the best bang per bit make sure to turn on VBR and joint-stereo.
You can probably reduce the bitrate selector to as low as it goes as it is an *absolute minimum* in Variable Bit Rate encoding and it needs to go low when it can so that it can go high when it needs to.
I don't use iTunes to encode but my lame
-encoded mp3s dip to 32kbps during moments of near silence.
I don't know which iTunes quality setting gives you 160kbps on average but I'm guessing medium
will be the one. You can always experiment, remember thrash metal will be higher than average and classical lower, as they are harder and easier to encode respectively.
