You may have an add-on for your browser that stops ads from appearing on your page as you surf. Now someone has come up with a version for online radio stations. Does it actually work? I have no idea, although a brief test seems to indicate it might. But if it does, radio companies won't be fond of it at all. 

The thing asks for an email address, which it uses as your I.D. You're then taken to a page with a series of countries, asking which radio stations you want in your profile. (There was only one from Canada - and it's from a French station in Quebec.)

Next you're asked to choose how your audio is filtered 

Musical mode
Music only, no ads, no chit chat
           
Ad free mode
Music and talk but no ads
  
No filter
Radio as it is traditionally broadcast, including ads.
 
And finally, pick your filtering action. 
 
Muting mode
Simply turn the volume down during ads
 
Hop and return mode
During ads, I listen to another radio, then channel hop at resumption.
 
Hop and stay mode
Avoid ads by hopping to another station.

I doubt this will be a huge deal, but it's out there and it's free. Here's how its creator explains what it does and why he designed it.

Curious to give it a try? Here's the site.
