FLAC files are average about half the size of .wav files. If space is an issue and your player handles FLAC files, then FLAC is your friend.
I just finished a ripping project for my space-limited 4 GB Sansa Clip+. The ripper was EAC and the format of choice was 320k Lame MP3s.
Thank you and yes myself, my wife, my daughter and her husband are with my grand children and their parents which is a rare treat due to distance.
keith, instal fubar2000 and the available abx plug in for it. use headphones while at ypur computer and experiment.
i cannot tell a difference between cd, flac, wave or 320 kbs mp3's. there may be some super rare material out there that can show differences but it is not common and differences are likely very small.
fwiw, i use flacs for home listening because it makes me feel better. portable devices get loaded up with my high bit rate mp3 files. when i rip i use dbpoweramp to create flac files and foobar to make 320 bps mp3 copies of all files. simple and easy.
