They really are MP3 files. >>> ewers@xxxxxxxxxxxxxx 09/19/05 10:07AM >>> But, Rob, I just transferred a wave file to bookport and it plays. When I look at what is stored on the flash card, there are the .wav endings with the typical extra endings assigned by the bookport. Are they really wave files, or has the book port converted them to MP3 files but simply has not changed the file ending?

Book Port can play 320 KBPS MP3 files with no problem. Book Port does not play wave files, with the exception of its own memos, which are 8-bit 11025 Hz. Rob Meredith >>> buhrow@xxxxxxxxxxxxxxxxxxxxx 09/16/05 09:03PM >>> Hello folks. Another question for this evening. What is the highest bit rate of MP3 that the Bookport can play? Is it 128Kbits? I'm just confirming that my impirical experience is right? I tried loading some 192Kbit mp3 files onto the Bookport, and it wouldn't play them. On a related note, what is the highest sampling rate Bookport can support in Wav files? -thanks -Brian
