The ID3v2 standard calls this "unsynchronize," so it's probably a safe bet to call it that here. Now that I understand the purpose of the mechanism (ie, modify MPEG synchronization bytes that occur in the tag data so that bad MPEG decoders don't try to read tag bytes as media), I think the name makes more sense than the more correct word "desynchronize".
