Listening to .WAV file on the server. How do I do this?

Question

Greetings,

 I have a table called audiofiles with two important fieldnames, fileID and filename.

 The value for filename looks like this:

 

cv9330033.

 

However, on the server, the filename is stored like this:

 

vook_cv9330033.wav

 

On my summary page, I have a link:

 

<asp:HyperLinkField DataNavigateUrlFields="uuid" DataNavigateUrlFormatString=http://servername/folder/play_audio.aspx?filename='vook_'{0} " +".wav" Text="Listen" />

I can get this link to reach the filename on the server and play the .wav recording.

 

Any ideas
