Audio glitch at beginning of every render?
 

For some reason there's a couple small clicks/pops at the beginning of every wav file that I export. It isn't there originally, it's only introduced after rendering wav files in vegas. What's going on?

Don't know if this can fix your problem but you might want to check if all your audio files are "fade offset" at the beginning.

Also check this isn't a playback problem when you're listening to the rendered files.
Can you see the glitch in the audio waveform when you re-import the files into Vegas or Sound Forge?
Have you exported the files to other portable audio players or computers, or different playback software on your own computer, and listened to them again?
