Over the past few years, podcasters for both the PC and Mac worlds have had a similar dilemma…how to inject audio into your live podcasts and shows. Many methods have been tried, and likewise, many have failed. To date, the only tried and true method for doing this was to purchase a hardware mixer and then be saddled down with a sometimes huge upfront expense and of course, maintenance, upkeep and eventually, replacement.
Nowadays, using a VOIP or SIP connection for your live podcasts and shows, is becoming the norm. Along with this connection, you have the opportunity to inject audio easily using a product called Vemotion from http://www.voiceemotion.com
Using Skype or XLite (or other SIP/VOIP client) along with Vemotion, enables you to play audio files easily. What this doesn’t enable you to do, is to play your audio, say from Talkshoe, back across another connection, such as uStream. So, when your viewers are listening to your audio on uStream, they will only hear you and no one else or your audio files that you are playing. So, this brings in yet another challenge for the podcaster…how to make THIS happen!
Like I said earlier, the best way was to spend a lot of money and purchase a hardware mixer. This isn’t practical for a lot of hobbyists, so a low cost, software solution had to be found. Introducing The Virtual Audio Cable, a low cost software solution that enables you to simulate a hardware mixer and redirect your audio to other places such as uStream.
The Virtual Audio Cable is for PC only and gives you the capability to redirect your audio using “virtual” devices. Now, just a quick caveat here…this solution is not for the technically challenged. That being said, I am adding a short how-to video on setting this software up and this should allow almost anyone to setup and start using this software in little to no time at all!
As many of you already know, I have had the hardware mixer for quite some time now. This has worked out quite nicely for me, except for when I need to go remote with my laptop and then, well, I can’t be dragging a bunch of extra hardware with me everywhere I go…can I?!? No! So, this is why I began looking into this solution real hard once again. I purchased the Virtual Audio Cable (just runs $29.00 USD) and was able to download it and install it and once the configuration was in place, I was able to start using it! In fact, I “debuted” the use of this solution on my show last night and it worked out great! Here’s a few tips for you to get you going…
To begin with, you can download a free trial version of the Virtual Audio Cable (and I recommend you do this BEFORE buying it) from http://software.muzychenko.net/vac409.zip …You can still use my instructions to use the free trial to make sure this works for you.
Once you have the trial software installed, there are two applications that you will be using, the Audio Repeater and the Virtual Audio Cable app. To begin, start the VAC app. You will need to setup at least one Virtual Cable. Here is a graphic showing you my setup right now:

As you can see in this picture, I have three virtual cables setup. You will have some limitations in the trial version, however, you only need one virtual cable to make this work.
Next, you need to run two applications of the Audio Repeater program. The reason for this is to redirect your audio through the newly created virtual cables. Here is my setup:

As you can see from the picture, I have my microphone on my PC going to Line 2 (a virtual audio cable. Yours may say Line 1) and on the second repeater, Line 2 going to my Speakers on my PC. Now, all audio is being redirected using the Virtual Audio Cable software. Next, click the Start buttons on each repeater program to start the virtual streams. Next, after you fire up uStream (or whatever program you are wanting to send your audio out to) make sure your audio source is your Virtual Audio Cable (for example, mine is Line 2) and then all audio will go to your redirected source. So, when you have people talking in the Talkshoe Chat Room or you are playing audio files using Vemotion, your other source will hear these as well!
I will post a video soon showing this entire process along with links where you can purchase this great product! Take my advice, download the trial version FIRST and then make sure it will work for your application! Watch for the video here soon!
