Hey guys!
Yesterday I had to convert a large number of files from flac to mp3. I
thought it is an easy task, but I was surprised to see that no Linux sound
editors I have installed can do batch processing. Converting by hand was not
an option and I had to use a proprietary solution, Gold Wave under WINE.
Am I missing something or is batch processing a feature currently
unavailable on Linux Audio?

hi Louigi,
you might use Gnome SoundConverter. That does the same in a graphical way.

Linux command line tools do batch processing very efficiently.

I guess that's because most batch 'stuff' in linux can
easily be done
from the terminal... For example for converting all files in a dir is as
simple as:
flac *
For more complex tasks taking the time to look at the find command,
which initially may seems overwhelming, is worth the effort IMHO

That is not the fault of linux, but the fault of your installation and your
abilities.
Others have already pointed you to the very powerful command-line.
Some days ago I installed and used soundconverter to copy some of my music (of
mixed source formats) to a usb-stick for a player that only reads mp3.
Have fun,

Hey guys!
Yeah, I am not saying it is anyone's fault and my CLI abilities are very
basic. Also, even when I do research such stuff, I forget it quickly. For
instance, I remember testing a CLI command to convert photos from one size
to another. It was very fast and efficient and I was really convinced that
it is much faster than firing up a GUI program. However, when I had to do a
similar task some months later, at that moment I had no access to the
Internet and I could not remember what command that was and how to use it.
So eventually I had to give up.
Same with file encoding. It does not come up very often, when it does - will
I remember the command?
I will try Gnome SoundConverter, thanks for this GUI suggestion. CLI
suggestions are also very welcome, I will try them anyway, of course.

a hint from someone with lossy memory compression:
after having successfully used such a command, scroll up in your history
to find it and write it into a new file, ie like
echo "for i in *flac ; do lame $i ; done" >> flac2mp3.sh
after all, that is what shell scripts are for.

That's why you put such commands into a bash script so you have it for
reference.
for instance:
#!/bin/bash
# flac_to_mp3
for f in *.mp3; do lame -v "$f"; done
Don't forget to make it executable:
chmod +x flac_to_mp3
A good reference is the Advanced Bash Scripting Guide:

The find command is a neat way to do lots of files also.
$ find . -name "*flac" -exec lame -V0 {} \;

Normally when I have to repeat a number of commands, I write a bash/sh-script.
That also helps in remembering. (One of the basic principles of programming
and administration, dry - don't repeat yourself.)
Only in this case of conversion/copying of files the resulting script would
have been to complicated for a ten-minutes hack (several subdirs with source-
files of ogg, mp3 and more as input converted to a target dir, preserving the
directory-structure while converting all files to mp3 when the target is the
mp3-only player and convert all to mp3 or ogg when the target is the mobile
player - thats the features that script would have needed), so I searched
aptitude for something and found the converter. It isn't as flexible as the
ideas I had for a script, but was faster to "write"...
Have fun,
Arnold

Well, there are lots of ways to do it, and GUI tools are usually
inferior, at least when you want to control your conversion exactly.
They often don't expose the encoders parameters properly.

I tend to document these things for myself in a wiki that lives on the lan.
The suggestions for putting them in a script work well too.

Oh, very interesting, because I tend to forget many important moves as
well. That is why, over the past few years, I have grown one huge file
