At least, it appears that way.
If you go to this web page on the C-SPAN site, there is a link to play the argument--presumably the link will go live a few hours after the argument has ended (and they have had time to upload the audio).
In addition, I have been told that it will be broadcast on C-SPAN at 8:00 p.m. EDT tonight, though I have found no independent confirmation of this.
UPDATE: I have now been told that the arguments will be played on C-SPAN radio, available here, at 3:45 EDT this afternoon.
