I'm using win xp with cool edit pro 2, I have Pentium 3, 1 gig 512 sdram, Nvidea graphics and I'm using a Roland ua30 usb interface and a 2 channel preamp for record and playback when using cool edit. I have soundblaster live for general use. I have been trying to eliminate pops and clicks during playback. I've turned off all background programs, ( gone through optimizing cool edit for win xp) and tried adjusting the buffer size and # without any success to this point. (I was wondering if buffer setting outside the norm might be optimal for this type of setup).My probem is when playing back and occasionally on recording I hear pops or clicks. Sometimes more frequently than other times. I would also mention that sometimes the opening notes on playback sound metalic the first time through, and sound better after starting over. Thanks for reading this. Any help would be appreciated. thanks

Are you hearing pops and clicks throughout the music, or just at the start?

For ones throughout the music - this often is because of sync problems between the various pieces of digital gear. You would need to check things like wordclock and sync source issues.

For ones at the start -- do you have a period at the start where there is no data on any of the channels? CEP will put a nice pop at the front of your piece if you do... just put a wave file of silence at the start on one of the channels and its happy.

One more question: Are the pops and clicks in the files you are playing, or just an artifact when you listen? In other words, if you zoom into the file, can you see the pops and clicks?
