[gentoo-user] Konqueror and mp3

Hi All,

I am looking at saving the mp3 files presented in Konqueror when looking at 
the contents of an audio CD.  Although I can play/copy .wav files fine, I 
cannot play .mp3 files shown in Konqueror.  All I get is a hiss no matter 
which player I use.

What do I need to do to be able to copy mp3s out of a CD?

What konqueror presents is just a virtual view. You cannot play anything else 
than the .wav's from a CD, because they're the only ones representing the real 
data.

If you have the correct encoders installed, copying the other files to some 
other place will encode the selected audio track(s) and store the result in 
the destination directory.

The correct encoders. See the audio cd section in KDE's system settings.

HTH...

Oh, I see.  When I copy an mp3 file I get a file which is 4.5MB large, so I 
thought that it has real music in it.

This is what I can see under kcontrol/audiocd:

I guess these settings are not enough on their own.  What else should I add?  
How do I specify the necessary encoders?

use constant bitrate, not vbr, just copy the mp3 somewhere and you will be 
fine.

I believe that once you've dragged & dropped one of these somewhere -  
resulting in a .mp3 file of about that size - they should indeed be  
playable. It sounds like something's broken.

Are you using  KDE 3.5.10?

I think your problem may be described in this article:
http://pclosmag.com/html/Issues/200907/page04.html

    But, if you want to rip MP3 files, you will have some extra work  
to do
    to get them to come out right. Due to a "bug" that crept into KDE
    3.5.10, MP3s do not encode properly. Without the "fix," all your  
MP3s
    will be nothing more than static-filled white noise.

I no longer consider MP3 as a particularly good format for compressed  
audio. You might want to consider the Ogg Vorbis option, although on  
other platforms you may need to install software to play this format.

Thank you both.  It seems that this is indeed a bug for KDE-3.5.10.  :-(

I tried both solutions and neither works.  The former creates a 4.5MB mp3 file 
which is full of white noise, the latter described in the article creates an 
empty file 0MB.

Is there another solution to this?  I need mp3 because the file will be 
ultimately played on a vanilla WinXP PC.

I have started using flacs - because they can easily be trancoded into mp3 or 
ogg. flacs are lossless so they are good intermediate format. Rip to flac, store 
cd away and encode to whatever you want/need whenever you want/need to.

Thanks for this.  I ended up copying over to my drive the flac file and then 
running:

for file in *.flac; do $(flac -cd "$file" | lame -h - "${file%.flac}.mp3"); 
done

Not sure if the bitrate is appropriate.  As is it was converted to a 48KB mp3 
file at a bitrate of 128kbps.
