Hmmmmm...okay, can I run the existing MP3 through a program like Goldwave and up the sampling rate or once it's set, can't it be improved? ----- Original Message ----- From: "doc" <talmidim@xxxxxxxxxxxxxxxxxx> To: <bookport@xxxxxxxxxxxxx> Sent: Monday, December 11, 2006 6:12 PM Subject: [bookport] Re: MP3 that won't play Walt your problem is not variable rate which i use with no problem. your problem lies in your sampling size. it shows 11000 hertz and that is too small. Even though it may be reccomended for voice that would give only a poor sound quality. i go no lower than 32bit at 22050 hertz.
