Hi guys,

I just switched to Lame for encoding of hunderds of music files.

I use the following command:
lame.exe -b 64 --cbr --nogap --quiet file1.wav file1.mp3

I then join all mp3 files using
copy /b *.mp3 final.mp3

The file plays great on my Windows Media Player and Winamp, however when I try to stream it through a web flash player, I get fast-forward. see here:
http://www.israel-music.com/efraim_shreibe...rim_shpil_3000/

The original file is here:
http://www.israel-music.com/temp/orig.mp3

Is there any way to fix that? What am I doing wrong?

Thanks!

Michael.

Thanks for the technical info Gabriel.

It's not much use being compliant if I can only play the first track of an album in foobar, or other players that rely on the TOC, though.

I just went to the URL quoted in the first post. Firstly, the result is hilarious. Secondly, could this double-time be caused by the fact that the data and initial TOC don't match?

Rather than me try to dig myself out of my hole I thought I could divert attention back on to the original question: why does the Flash player have trouble with these files?

While you ponder that I'm ducking back under the stone I crawled out from...

I *think* that the reason could be that the mp3 is mono, and flash assumes it is stereo.
If the reason is really this one, you can't fix it, except if there is an option in flash to change the number of channels.

Edit: It could be the samplerate too, but i thought flash supported them.
This could be easily tested by simply using a non-concatenated file couldn't it?

mluggy, do you get the same issue using one of the original files (before you merge it using COPY)?
