I'm wondering how to make the smallest possible files for converting/importing some of my audio books on CD onto my 665c memory sticks. I convert digital files using iTunes and can get a 4-5 minute song down to about 3.5 meg by making it an mp3 at 96kbs (the lowest setting that is still sampled at 44.100 khz). I can go down as low 32kbs and still keep the sample rate at its required 44.1 for mono audio. I've read somewhere there is a way to get smaller files yet by converting to AIFF or WAV format. I know iTunes will let me convert to both, but my first AIFF files turned out huge. Any help?
Also, will AIFF files (or WAV) play and display the same in Audio Player as my current mp3's? Will they make albums the same in mp3 Manager? Are these formats appropriate for both music and speaking quality?
Lastly, if I had a bunch of audio-book files (in whatever format) in my Audio Player is there a way to exclude them when I'm listening to my tunes in the random 'Shuffle' format on my player?
