# Video by Kyle Rankin, pg-100

for i in *.mp3; do
lame --decode "$i" "`basename "$i" .mp3`".wav
Make the script executable
guest@kusumanchi:~/bin$ chmod +x mp3towav
guest@kusumanchi:~/bin$ ls -al mp3towav
-rwxr-xr-x 1 guest guest 450 2007-03-06 20:19 mp3towav
Cd into the directory containing .mp3 files
guest@kusumanchi:~/bin$ cd /entertainment/telugu_songs/godavari/
guest@kusumanchi:/entertainment/telugu_songs/godavari$ ls -1 *mp3
01 - Ramachakkani Sitaki.mp3
02 - Uppongele Godavari.mp3
03 - Manasavacha.mp3
04 - Manasaa Gelupu.mp3
05 - Tippulu Tappulu.mp3
06 - Andamgaalena.mp3
Run the script
guest@kusumanchi:/entertainment/telugu_songs/godavari$ ~/bin/mp3towav
There will be messages such as
ID3v2 found. Be aware that the ID3 tag is currently lost when transcoding.
input: 01 - Ramachakkani Sitaki.mp3
(44.1 kHz, 2 channels, MPEG-1 Layer III)
output: 01 - Ramachakkani Sitaki.wav (16 bit, Microsoft WAVE)
skipping initial 1105 samples (encoder+decoder delay)
Frame# 8878/8859 128 kbps L R
The corresponding .wav files will be created once the script completes. The .mp3 files are unmodified.
guest@kusumanchi:/entertainment/telugu_songs/godavari$ ls -1 *wav

02 - Uppongele Godavari.wav
03 - Manasavacha.wav
04 - Manasaa Gelupu.wav
05 - Tippulu Tappulu.wav
06 - Andamgaalena.wav
Programs like k3b can now be used to burn these wave files onto a CD/DVD.

The website does not load. What is the advantage of using this compared to lame? Is it open source? I will be deleting the comment if there are no relative advantages.
