How do I put the link on my web page in order to use the free version? What are the requirements?

Simply copy and paste the following code into the html of each page that contains a link to BroadWave:

Audio Streamed by the <a href="">BroadWave Streaming Audio Server</a> by <a href="">NCH Swift Sound Software</a>.

You may need to ask your website administrator to do this for you.
