When using audio preview in Virtualdub, frames are dropped. Would very much like to be able to audio preview during capture
This is usually not an option.
The only time you can preview audio, while using VirtualDub
, is when audio is routed into a sound card, and the card is fancy enough to have multicast-type features. The ATI All In Wonder card in use on my primary Windows XP capture system use a Turtle Beach card. While audio is muted in VirtualDub (line input effectively muted), the audio processor on the card still passes out to the speakers. So I can hear the audio, even while the preview is muted.
The only alternative I can think of here is to split the audio before it hits the capture card. Route one into the audio card input, and route the other into the ATI 600 connections. I do this, too, with a Tevion card setup. My "splitter" is a Behringer mixer board
. A also have a DataVideo VP-299 distribution amp, and then anybody with a TBC-1000 from B&H
has that same ability (since the TBC-1000 is a TBC-100 married to a VP-299).
So we can do what you want -- to hear audio while capturing -- just maybe not with a method you'd yet considered.
