Execute this in the root of your music library and this recurses through the directories and normalizes each folder containing mp3s as a batch. This assumes those folders hold an album each. The command "normalize-audio" may go by "normalize" on some systems.
-2find . -type d -exec sh -c "normalize-audio -b \"{}\"/*.mp3" \; -
This heavy one liner gets all the files in the "/music/dir/" directory and filters for non 44.1 mp3 files. After doing this it passes the names to sox in-order to re-sample those files. The original files are left just in case.
-2file /music/dir/* | grep -v 44.1 | sed 's/:.*//g' | grep .mp3 | { while IFS= read; do filebak="\"$REPLY.original\""; file="\"$REPLY\""; mv $file $filebak; sox -t mp3 $filebak $file rate 44k; done; }; -
