Hi,

Yes the value given 16kbps 22000Hz are the "real value" these are the value that I choose during conversion from Real Audio file to mp3
using a streambox ripper version that I found on the net.
I know that this program is no more distribute, so if someonme now a freeware , even a commercial product to convert realaudio to mp3
with some batch file (recursive directory will be a plus !) , and that convert it fast !
Cause some tools like dbpoweramp convert it but at the same speed as the play speed !!! so to convert 2000 audio files each of 90 mins lets compuklte how many days I'll need.

Indeed I think that now my file will be correctly displayed.
Only hope it I mjust go to home in 2 hours and test it, so I'll report it.

Another interesting things is that the archos firmware display it without problem for the legth, bitrate, frequency ? do they support the non standard mpeg 2.5 ?

And a last things in the last cvs modification I saw a reference to this URL : http://rockbox.haxx.se/docs/mpeghdr.html
but it seems to be broken !

That's all
