DELAY IN AUDIO RECORDINGS, AUDIO STREAMS OUT OF SYNC
I'm having a problem with call monitoring. The audio streams are out of sync in my recorded audio files. As we all know, on a phone conversation, there is a full duplex audio signal. That means there are two strains incoming and outgoing. Well, when you record this, you should hear the audio synchronized. When one person speaks and the other responds, the timing should be just like a real conversation. However, something is causing the two streams to be out of sync.
When listening to call recordings, I'll hear the person on one side of the conversation speak, then the other side doesn't speak for a few seconds. There is a lag and I'm not sure where to begin trying to figure where it's coming from.
thanks, everyone in advance for your help.
check the load on your box
check the load on your box when recording. If you are also doing this in a virtual machine this is common it the box does not have enough cycles to process things in a timely fashion. VM's are great for playing and testing but are NOT good for a REAL production box as you do not have control over what the other VM's are doing at any given time. Good quality audio is a time critical thing and slicing time up (which is what a VM does) just does not cut it in a real world situation.
