Is there a software to confrence two audio streams together - for eg:
Scenario 1:
I am talking to userA on Skype and userB on Yahoo Voice and all three of us can hear and talk to eachother?
Scenario 2:
I am talking to userA on any pc voice call (msn, yahoo, skype etc) and If I play an audio/mp3 file on local PC, and userA can listen it too?
Basically, in Scenario 1 & 2, there are two audio 'streams' that I am dealing with but they are being kept diffrent at my PC - why can I not 'merge' them at the hardware level to make it a confrence??
