linux find and cp/mv to a path

If you want to find for a particular string/date and then do list/copy/move, then below command will help you out

Find .wav files created on Dec 30th
 find . -type f -name "*.wav" -newermt 2016-12-30 ! -newermt 2016-12-31 -exec ls -l {} \;

If above cmd shows proper output then try
find . -type f -name "*.wav" -newermt 2016-12-30 ! -newermt 2016-12-31 -exec cp  {} /dest/path/ \;
