Hi I am running mpg123 to convert my files from .mp3 to .wav
I am doing it this way
mpg123 -w <filename>.wav <filename>.mp3
This works fine for me. But I was wondering if someone knew if there was a way to convert ALL my mp3 files in a directory to wav files with ONE command. something like this...
mpg123 -w *.wav *.mp3
(which i know doesn't work)
My second question is whether or not anyone knows of a GUI that converts mp3 to wav with a drag and a couple clicks of a mouse.
Cheers,
Chris

Don't know about mpg123 but I found that using a lame script "mlame" coverts all my .wav to .mp3 automatically:

~/kencaz/./mlame -r -o "-v -V 0 -b 112" *.wav *.mp3

This will convert all file in my current foder from .wav to .mp3. I don't remember where I got the script but it's kinda hard to find so I'll include it here. You'll have to save it to a file then change permissions as usual...

#!/bin/bash
#!/usr/local/bin/bash

I had this same problem so I wrote a quick and dirty perl script to do this for me. Dump your files to be converted into a temp directory and it will go through them one by one and run the mpg123 command. It renames them to 1, 2, 3, ...ect .WAV files.

#!/usr/bin/perl

my $dir = "/change/this/to/your/directory";

opendir DH, $dir or die "Can't open $dir: $!";
$count2=1;
while ($name = readdir DH) {
next unless $name =~ /\.mp3$/;
$wav="$count2.wav";
print "$wav\n";
system "mpg123 -w $wav \"$name\"";
$count2++;
}



So I just changed the line
my $dir = "/change/this/to/your/directory";
to my directory where i hold my mp3s but the script didn't work...nothing happened. Any ideas why?

Thanks,
Chris

This little diddy from my notes should get you going.....
or using lame might look like this...

This part is in quotes to handle names with spaces in them "`basename "$i" .mp3`"

Hard to say. Are they all named ".mp3" ?? if they are named something like blah.MP3 add an "i" to this line: "next unless $name =~/\.mp3$/" so it looks like this:
next unless $name =~/\.mp3$/i. This will ignore case.

Otherwise did it give you some kind of error? I just used the script a few minutes ago as is so I know it works.

Script in ruby:

files = Dir.entries(".")

for file in files
if file.include?(".mp3")
file.gsub!(".mp3", "")
system "mpg123 -w '#{file}'.wav '#{file}'.mp3"
end
end

And I know: the post is old, and script is simple as possible

For those who aren't scripters, here's a start toward a simple if verbose kludge:
