For audio books on CD I obtain from the public library and rip to listen on my MP3 player, I use a 44.100 sampling rate and 96k bitrate. I have found that I lose some of the emotion and distinctness of the reader at 64k. At that lower bitrate, the recording sounds flat. Broadcast radio standards do call for 128k bit rates. For personal listening of voice recordings, 96k is a good compromise for me between broadcast quality and the 64k used in many online archives. I’m especially keen to the trade offs as I am still using an original Bookport with a 512 megabyte card.
