Cracking sounds can be caused my 2 things mostly (as discussed many times on this forum before):
[li]The reader is not very well capable of Digital Audio Extraction (DAE) and causes the crackling sounds and clicks in the extracted files
[/li][li]The writer can not burn properly at higher speeds
What you can try is the following:
Try to extract the audiofiles to *.WAV files on your harddisk. Thenm play the *.WAV files in mediaplayer/WinAmp. If no clicks or crackling sounds can be detected the problem lies somewhere else. (you should try this both in the reader as well as your writer, usually your writer is better equipped to deal with DAE)
Try the lowest possible speed to burn the *.WAV files onto CDR (try different brands too, this might help sometimes too). If no clicks or crackling sounds can be detected, try the next one at one step higher speed, and continue this process until you detect the crackling sounds again.
Further, use our search function to see what has been written and suggested in other cases, it might help find the solution to your problem
