Best practive to reeendoce previously 64k speech/music audiobook (Audi

Let's say I have an original 64k Audible file (we are not sure if it is an MP3 or AAC in it). eMusic uses 64k MP3s.

I can legally extract the audio out of it by various means; I get a WAV. What is the best method to reencode this WAV not to waste that much space on my MP3 player but also does not sound like cr*p?

I have found anything below 64k (Audible 'Enhanced') sounds cr*p.

Strangely, Audible also offers some meditation music, poems with a musical background also as audiobooks, encoded maximum at 64k. Should I reendoce them differently than strictly speech audios?

If your player supports other formats like Ogg Vorbis or WMA, go for it. If your player only supports MP3, I highly recommend GXLame, it's smaller than LAME -V9. Still is VBR, but it's smaller. VBR is better than CBR at size and quality ratio.

Information about DRM cracking is against this forum's terms of service, so the information you can get would be down to those you can legally extract. What do you get from ffmpeg -i <filename>  ?

As for re-encoding the decode, you do get generation loss. B kbit/s lossy decoded and re-encoded into B kbit/s lossy is not the same as the original - not saying you will actually hear the difference - but the way to tell is by ear. Consider lossies on your mp3 player as disposable, and if they aren't good enough: throw away and re-encode.
