It is more like 80-85 kbit/s ogg sound like 128 kbit/s mp3s. It also depends on the audio material. A nice test are cymbals. There are also some bad mp3 encoders around. If you enable vbr with mp3 you can also gain some sound quality. The big adavantage of ogg is at low bit rates. I am encoding my audio books about 18-20 kbit/s vbr, mostly in 22050 Hz samplerate and mono in ogg format. This sounds o.k. for me. an alternative would be aac. I did some tests with the Nero AAC encoder http://www.nero.com/nerodigital/eng/Nero_Digital_Audio.html which also produces nice to hear audiobooks at low (18-20 kbit/s) bitrates. I sometimes think even a little bit better at 16 kbit/s than ogg at the same. Unfortunatly Nero AAC produces .mp4 files which can not be handelt by 770's audio player. You have to demux the audio stream out of the .mp4 container. I used mp4ui for it. Maybe I wouldn't miss ogg that much if we would have a nice (free) aac batch converter. Any ideas? -Klaus -- Klaus Rotter * klaus <at> rotters <dot> de * www.rotters.de
