Is it possible to adjust the volume of individual tabs in Google Chrome?

I've found [an extension that allows the volume to be muted](https://chrome.google.com/webstore/detail/mutetab/acofndgbcimipbpeoplfjcapdbebbmca), but it does not allow variable volumes.

**UPDATE**
Years after asking this question, it looks like a solution is finally available!!! [@peta-sittek](https://superuser.com/users/218892/peta-sittek) created an extension to perform this exact function!
