WAV and MP3
Converting *.mp3 files into *.wav files (or vice-versa) can be done quite easily under Linux. However, searching Google for mp32wav or wav2mp3 gives sometimes results, which do not actually work...
Here are guidelines, which work:
Convert MP3 into WAV
Use the program mpg123, which is part of the SuSE distribution (current
version 0.59r) and enter the following:
mpg123 -w song.wav song.mp3 (Notice: outputfile comes first, then the inputfile; for whatever reason...) And: the command mpg123 -b 10000 -s song.mp3 | sox -t raw -r 44100 -s -w -c2 - song.wav as described on some web-pages, does "work", but the output file in *.wav format does have an undefined end!
Convert WAV into MP3
Conversion from *.wav into *.mp3 format can easily done with the program
bladeenc; just follow the steps described below:
- http://bladeenc.mp3.no/ - Click on "Sourcecode" (left frame) - Click on "Click here to go to the source archive" - Click on the link next to "Latest Stable Source:" (in this case bladeenc-0.94.2-src-stable.tar.gz ) - Download file in a directory of your choice - gunzip bladeenc-0.94.2-src-stable.tar.gz - cd bladeenc-0.94.2 - configure - make - cd bladeenc - cp bladeenc /usr/local/bin/. (maybe this has to be done as root) - Convert *wav file into *mp3 file: bladeenc song.wav song.mp3 (the size of the mp3 file will be approx. 10% of the wav file)
I have listened to songs sampled with various bit-rates and the songs with
128 kbps sounded really like CD-quality. For a comparison of various bit-rates
see the web-page of the
If you get mp3-Files with other bit-rates (e.g. using qtella you may convert them first to *.wav files and then to *.mp3 files again (now with 128 kbps bitrate).
Below, I include two scripts (
which I have stored on
/usr/local/bin and which I use to convert
mp3 files into wav files and vice-versa.
# mp32wav 2.6.2001 / uk # mp3file="$*" for file in `ls -1rt $mp3file` ; do echo "$file" wavfile=`echo $file | sed s/\\.mp3/.wav/` echo $wavfile mpg123 -w $wavfile $file done
# wav2mp3 2.6.2001 / uk # wavefile="$*" for file in `ls -1rt $wavefile` ; do echo "$file" mp3file=`echo $file | sed s/\\.wav/.mp3/` echo $mp3file bladeenc $file $mp3file done
