Question: can i get the wav file as an attachment to my email notification?
Unfortunately, No. WAV files can be pretty big and we send a lot of mailers everyday. So, attaching it will choke our mail servers.
Having said that, In the near future, we will move to MP3. If you are on Gmail, there is already various solutions to playing the MP3 file inline.
Here is where you should begin: https://www.google.co.in/search?q=gmail+mp3+player
