I recently got an audio file that was edited to add an echo effect, I was enjoying it when I started hearing this horrendously loud cracking in the audio file. I would fix it myself, but I cannot find the original song, nor do I know what effects they may have added, so if anyone knows what I can do to remove these cracks without physically going into the audio file and picking out the sounds, please let me know.
OK, so the clicks in this recording seem to be from clipping. I do not have a lot of experience with repairing this kind of damage, but you can try
running Effect > Clip Fix here: Clip Fix - Audacity Manual
