Script
                $FFMPEG -i "$file" -vn -y extracted.wav
                echo Now Normalizing the audio
                $SOX extracted.wav normal.wav -V3
                echo Now converting "$file" to "$tsfile"
               
 $FFMPEG -threads 0 -i "$file" -i normal.wav -map 0:0 -map 1 -vcodec 
libx264 -preset superfast -x264opts keyint=75 -x264opts vbv-maxrate=900 
-vf scale=720:288 -bufsize 2M -r 25 -acodec libfaac -ab 128k -ar 32k -ac
 2 -async 1 -f mpegts "$DEST_DIR/$tsfile"

Step 1
Now extracting audio from /mnt/media1/Jukebox_upload/Front 242 - Headhunter.mpg

Ive tried the "-i normal.wav" at the begining and after the video parameters, but seem to get this error every time, any ideas why it seems the audio as a 2 channel wav and wants to decode it?
