Default Audio sample rate produces crashes

Hi all.

A podcast source that I'm fond of makes my T10 crash. I've tried with many firmware up to 3.07 " la fleur" without luck. When reading the T10 immediatly shuts down,and sometimes a reset is necessary. In any case it can't read it. You can try the files for yourself e.g. at http://podcast.bfmradio.fr/channel9/...ier17h_rmc.mp3. Thanks for your reports, I'm interested to know if there's something broken in mine.

I think to have found the reason why it crashes, and a way to reencode the files as well. The problem is the audio sample rate which is 32 kHz in this file. For example, mplayer -identify gives ID_AUDIO_RATE=32000. I've solved this by reencoding with a 44.1 kHz sample rate, using lame:
lame -v --resample 44100 20090606_atelier17h_rmc.mp3 test.mp3
produces a readable file (I'm currently listening to it).

Hope this helps,

Eric

what player is this ?, I just can see how a mp3 file encoded at 32k unless you are refering to the Mp3 data rate..

When audio CD are converted to MP3 its done from the audio output not the digital sample rate.

Search Google. But, for a quick hit it's a Linux media player.

mplayer runs on windows too. Again, Google gives a quick answer.
As well as lame, look e.g. here. See also WinLame for easy point-and-click use.

I'm a bit disappointed nobody tried the file on his own T10 to report if I have the only one that crashes with this sample rate, or if this could explain the crashes that I've seen reported here and there. There's no risk guys, I haven't bricked mine !

Best anyway,

Eric

Well I did try it the MP3 Sample rate is 56K and that is all that is needed for speech, tried 2 players they both state 56K, Media Monkey and the WMP.

Runs OK on my firmware 3.07 " la fleur" T10 made in China model.

i tried the file, T-10 EU 3.06, and had no problem playing about a minute of it.
i used a program called MP3cut and it reported that the file was 56K as well.
