Emailing via the Call Log_Audio Files

I would like to submit a request that we have the ability to decide if we need the Audio Files that get attached to emails, to be wav vs. mp3.  Currently mp3 is the default, but we need them in wav.  I am aware of the other ways of getting wav.  However, we would love to be able to utilize wav within the emails being sent via the call log.

Thanks, 

Mary Digney
