Music cd burn

Allo.
I do a program using shell script to burn cds and dvds because I don't want to install one with kde or gnome dependance. I want to optimize one of my shell script. this shell script is to burn music cds. I juste have to go in shell and write :
burn_cd_music audio1.mp3 audio2.mp3 audio1.ogg audio1.wav
and the shell script copy file in /tmp/cd_temp, converte them in .wav and burn the cd. It's fonctionnal, but I don't want to have temporary file.....
Can I use pipe or buffer to do that, and how?
Sorry for my english, if you don't understand, I will try to better explain

Give me you ideas
My script is:
#!/bin/bash
#do a liste of the mp3 files and one for the ogg file
for i in $@
do
j=`echo $i | cut -f2 -d '.'`
if test $j = 'ogg'
then
list1="$list1 $i"
fi
if test $j = 'mp3'
then
list2="$list2 $i"
fi
done

#copy the file in /tmp/cd_temp (I don't want to do this)
mkdir /tmp/cd_temp
for i in $@
do
cp $i /tmp/cd_temp/
done

#go at the files directory
cd /tmp/cd_temp

#convert the ogg file in wav file
for i in list1
do
sox `basename $i .ogg`.ogg `basename $i .ogg`.wav
rm `basename $i .ogg`.ogg
done

#convert the mp3 file in wav file
for i in list2
do
mpg123 -w `basename $i .mp3`.wav $i
rm `basename $i .mp3`.mp3
done

#burn CD
cdrecord dev=ATA:0,0,0 -eject speed=2 -pad -audio *.wav

#erase the temporary file
rm -r /tmp/cd_temp/

oggdec

oggdec(1)							   Vorbis Tools 							 oggdec(1)

NAME

       oggdec - simple decoder, Ogg Vorbis file to PCM audio file (Wave or RAW).

SYNOPSIS

       oggdec [ -Qhv ] [ -b bits_per_sample ] [ -e endianness ] [ -R ] [ -s signedness ] [ -o outputfile ] file ...

DESCRIPTION

       oggdec decodes Ogg Vorbis files into PCM-encoded ("uncompressed") audio files, either Wave or RAW format.

       For  each input file, oggdec writes to a filename based on the input filename, but with the extension changed to ".wav" or ".raw" as appro-
       priate.

       If the input file is specified as - , then oggdec will read from stdin, and write to stdout unless an output filename is  specified.  Like-
       wise, an output filename of - will cause output to be to stdout.

       Writing	Wave format to stdout is a bad idea.  Wave requires a seekable medium for the header to be rewritten after all the data is written
       out; stdout is not seekable.

OPTIONS

       -Q, --quiet
	      Suppresses program output.

       -h, --help
	      Print help message.

       -V, --version
	      Display version information.

       -b n, --bits=n
	      Bits per sample.	Valid values are 8 or 16.

       -e n, --endian=n
	      Set endianness for 16-bit output.  0 (default) is little-endian (Intel byte order).  1 is big-endian (sane byte order).

       -R, --raw
	      Output in raw format.  If not specified, writes Wave file (RIFF headers).

       -s n, --sign=n
	      Set signedness for output.  0 for unsigned, 1 (default) for signed.

       -o filename, --output=filename
	      Write output to specified filename.  This option is only valid if one input [file] is specified, or if raw mode is used.

EXAMPLES

       Decode a file enabler.ogg to enabler.wav
	as little-endian unsigned 16-bit (default options):
	      oggdec enabler.ogg

       Decode a file enabler.ogg to enabler.raw as headerless little-endian unsigned 16-bit:
	      oggdec --raw=1 enabler.ogg

       Decode enabler.ogg to enabler.crazymonkey as unsigned 8-bit:
	      oggdec -b 8 -s 0 -o enabler.crazymonkey enabler.ogg

       Decode enabler.ogg to enabler.raw as big-endian signed 16-bit (any of the following):
	      oggdec -R -e 1 -b 16 enabler.ogg
	      oggdec -R -e 1 -b 16 -o enabler.raw - < enabler.ogg
	      oggdec -R -e 1 -b 16 - < enabler.ogg > enabler.raw

       Mass decoding (foo.ogg to foo.wav, bar.ogg to bar.wav, quux.ogg to quux.wav, etc.):
	      oggdec *.ogg
