[FFmpeg-user] possible to do mp3 @ 48kHz

[Jim Shupert]

friends

I am successful  transcoding files with

ffmpeg -i D:\path\vid\my.mpg -ab 192000 -ar 44100 -b 8000000 -s 720x480 
-vcodec libxvid  -acodec libmp3lame D:\path\vid\my.avi
ffmpeg -i D:\path\vid\my.mpg -ab 192000 -ar 44100 -b 1500000 -r 30 -s 
720x480 -f flv D:\path\vid\my.flv

but the problem is i would very much enjoy having the audio sampling 
rate of 48kHz ; -ar 48000

and libmp3lame only will do 44100 , 22050 , 11025

so if i really wanted to have mp3 48 kHz audio --- is there any solution?

thanks
