Stuttering Audio from Capture Ingest

Advertisement

I have been having a problem for a while now.  When ingesting a tape or direct line, sometimes the audio on the record will begin stuttering.  At a seemingly random point, the audio of the record will begin to loop a 1 second bite over and over until the record is complete.  Confirmed it is the capture by playing the clip in other programs.  Odd thing is the real time playback as it is capturing will sound fine.  I end up knowing there is a problem when the capture is complete, because the "Save Captured Clip" window will fail to pop up when it reaches the out point.  Instead it will continue to record beyond the set out point.
There is no consistency where this audio fail happens.  Sometimes it won't even happen at all.  This has happened with DVCPRO tapes, Sony HDCAM tapes, and even a studio line cut from our switcher.  Any insight or suggestions would be helpful.

Typically, "stuttering" can be a result of either low signal strength or high signal noise values, or both.
It is very possible that you may have some form of Wi-Fi interference in the immediate area that is preventing your AirPort Express Base Station (AX) from getting a good clean signal.
I suggest you perform a simple site survey, using utilities like the following to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible:
For Macs:
o MacStumbler
o iStumbler
For PCs:
o NetStumbler
o WiFi Manager
