Hi. I have been making some slight adjustments to my vocal regions in Logic express using gain change and pitch change. Very small increments. I found, after making a full pass with these corrections and not hearing issues, playback of the track produced clicks in the audio. I turned off all inserts, still clicks. I deleted sections and brought in backup, still clicks. Finally, I imported the original sound files and this fixed it but, I did not have the pitch and gain corrections. Looking at the corrupted files I could see no clips or drop outs. Does making minor gain and pitch corrections lead to clicks if done improperly? Thanks for your help.
