Solve : Adding number prefix based on text in file name?

1.	Solve : Adding number prefix based on text in file name?
Answer» Hi, Noob here. I'm trying to learn some basic unix to make some mundane tasks easier. In my job I often get surround SOUND AUDIO files provided and manually ADD numbers to retain the order for injest into other programs. I have seen some commands for renaming or replacing text in strings, however I don't think this will help. audio.L.wav audio.R.wav audio.C.wav audio.Lfe.wav Would need to BECOME 1_audio.L.wav 2_audio.R.wav 3_audio.C.wav 4_audio.Lfe.wav Does anyone have an idea of the best way to have a script recognize the .L.wav in the file name and just add a 1_ to the BEGINNING? Many thanks in advance.
