Another annoying click when mastering to CD-R -Sound Forge - PC

Subject:Another annoying click when mastering to CD-R Posted by: wardo27 Date:11/6/2001 8:45:28 PM I'm kind of a novice at this so please bear with me...this is something similar to a post about a month ago, but the solutions didn't seem to work for me. I'm mastering to CD a set of tracks (originating from both LP & CD) that I exported from SoundForge 4.5 and I'm getting a loud click at the heads of any track that I originally recorded from an LP. The click is not on the original wav. The troubleshooting section in the program suggests that I change the Wave Pre-Load buffer back to "0" - I did that but the problem persists. Troubleshooting also suggests that the sound card can't handle it (which seems hard to believe as it's new and I've burnt other discs this way from CD-original material and haven't had the problem). I've tried to get in touch with the sound card manufacturer but they haven't gotten back to me yet - I was wondering if anyone might have some advice, or other things I could check. Perhaps something in my settings is off? Let's see, what else...my CD-RW drivers are up to date...I've tried recording at both high and low writing speeds and the problem stays the same...I'm on Windows 2000...I guess that's about it. Thanks very much - hope somebody might be able to help. Jon

I believe that "click" is the summary information or regions/playlist that is saved along with your (wav.) file when you first saved it. (Or something like that. Anyone?) To avoid any clicks when burning to CD, I always save my (wav.) files without saving the regions/playlist. I also chose not to save the summary information in the file. These options are selectable on the screen when you choose the save/save as option. Sound Forge 5.0's "Create CD" option doesn't seem to make these information clicks audible. (Yea!) But most CD burning software might. I may be wrong about the specifics as to why the clicks occur....but the solution I mentioned works for me. Hope that helps. And if anyone out there wants to CLEARLY explain why these clicks appear, please do so....I wanna know too. Cheers. - pup
Subject:RE: Another annoying click when mastering to CD-R Reply by: RickZ Date:11/7/2001 12:41:32 PM Don't know if this is same problem, but I recently went round and round with mysterious clicks at junction of .wav files, ie transition from one track to next on CD had a click, sometimes. But playing the files back on Vegas, no click . . only on CD-R playback. I'd used SF5.0 to select one song from a medley, Ctrl-C to copy the selection, then Ctrl-E to paste to new., repeating 3 more times for the other 3 songs. I use CDRWin to burn cd's and I'd created a cue sheet with no pre-gap between these tracks, ie 1:1 tracks to .wav files. After carefully reading the CDRWin help, I saw a clue, that tracks are written to nearest frame, 1/15th of a second, if I remember right. If a file ends just into a new frame, a blank fill is done on the rest of the frame, causing the click. To get around this, I left the 4 song medley as one file, and modified the cue sheet to create 4 tracks from the one file, with index points at the appropriate time interval. Problem solved, no more mysterious clicks. FWIW . . Regards, Rick Z

Run DC Offset correction on each of your files and then inspect the beginning and end of each file and remove any remaining spikes (if any). Good luck! Regards, Brent
