Sup guys, I've veen using Vdub for several years now, so it was the natural choice to use for capturing a live video feed for a recent project. I've worked out several bugs that were occurring when other software was running and taxing the video capabilities of the system, and now have everything working simultaneously nearly flawlessly.
The only issue left is more of a nuisance than anything. I need to record from two microphones, however not on the same audio track. They also don't necessarily need to be recorded at the same time either. My original idea was to find a mixer and switch between mics on the fly, or to build a hardware switch so I can alternate mics. Finding an appropriate mixer turned out to be harder than I thought, and ultimately decided the best solution was to get a secondary soundcard and swap between devices when need be. Which is what I did and it works as expected.
The only issue is that I can't change capture devices while recording. I'm forced to stop capture, select the desired device, and finally create a new file. Ideally I'd like to do this on the fly without creating a new file which I understand may be impossible. What I know would be possible, but just isn't a current option, is to capture a secondary audio stream (in real time) in addition to the primary stream. Each using a dedicated recording device. Is this feature available in any previous, or alternate build aside from the current version? Would it be very difficult, or too much to ask for this feature to be added to a future release? There are no hardware limitations aside from having the processing power to capture a video stream as well as two audio streams simultaneously, which any modern rig is plenty capable of.
Any ideas? |

Two persons speaking? In the same room or another?
OK, let's say you don't care about crosstalk. Why don't you record the second mic separately (but at the same time), either on the same PC or on another, and before the start just make a loud bang and synchronize on that in audio editing.
In any other case, I can't imagine the need for one person to talk into two mics.

It's two seperate mics, one recording outside, the other inside.
I've considered running multiple instances of Vdub, but it seemed a little unstable, and ran into a couple software crashes during testing, although it did technically work. I would also need to add a second video capture source, or at least use a dummy source. The goal is to simplify the process as much as possible as it's fully automated and I have to write scripts to execute all commands with no user input. I'll go back to testing dual instances and try and track down what was causing the crash, probably just the sequence I was using to start/stop capture, or the dummy source I was using.
Secondary stream capture support would be the ideal solution though. But if it doesn't exist, I guess all I can do is hope, or plead for it to be added. Actually kind of surprised it doesn't already exist considering how versatile Vdub is. |

Mono/stereo mics? Can you use something like this?

I considered combining with a Y adapter at first, and even tested it. It did work, but I wanted control over the volume of each mic. I ditched the idea of mixing the mic into one track when decided to add a second sound card. I actually never really wanted to mix them, but build a hardware switch so I can select between the two. I'm probably just going to add a webcam to the setup as an excuse to run two instances and record a second track as described in the last post. |

I haven't tried maybe one audio device uses ms sound mixer, the other use asio !! |
