Shell Programming and Scripting

Hello Even though I have been using Linux for quite a while my knowledge of the command line is pretty limited, now I am beginning to understad why it is considered so powerful.

I am going to give a little introduction of what I need.
I am a "believer" of the music tuned at 432hz, this is considered the old fashioned tunning, most cathedral bells are tuned at this frequency, in the early 21st century someone decided to change it to 440hz, this made the music sound different, many people think this made the music not sounding as well as it used to be. There is a lot to discuss about it.

I am not the only one that thinks than repitching music makes it sound better, I found out the command line (using the program sox) that repitches the music from 440hz to 432hz.

Code:

sox music440Hz.wav music432Hz.wav pitch -31

then someone with a bit more knoledge of the shell told me how to make it so it will change all songs in a directory, just cd to the directory and then...

Code:

$ for f in *.wav ;do sox "$f" "432Hz_$f" pitch -31  ;done

This makes the work a lot easier, but... i guessthere must be a way to have the work done in ALL my music collection.
Would that be too hard to make? I guess not with the right knoledge and skills.
Any answer is welcome,
Thanks!

Code:

find /basedir -name "*.wav" | 
while read pathname
do
    dir=$(dirname $pathname)
    file=$(basename $pathname)
    sox "$dir/$file" "$dir/432Hz_$file" pitch -31
done

...should do the trick
