	Note: many options are dependent on the codec or external compressor (encoder). So, often no clear recommendation can be given. It is important that the user has a general understanding of what these settings do and how they possibly change the behavior of EAC and/or the [[codec]]/external compressor.

	Some encoders have the ability to store a [~~http~~:~~//en.wikipedia.org/wiki/~~Cyclic_redundancy_check CRC] checksum (cyclic redundancy check) in the resulting (compressed) file. This might be used then to check the consistency of this file during playback. But enabling this CRC check has two major drawbacks: First, this will add 16 bits (the CRC value) on every frame of the encoded file and will possibly increase the file size considerably. Second, many encoders do not support this feature very well because of calculating wrong CRC checksums. So usually players will simply ignore this information. This option also has no effect at all when selected ''User Defined Encoder'' at the ''Parameter passing scheme''. Thus having more disadvantages, it is generally recommended to disable this option regardless of the encoder used.

	As ID3v2 tags are usually placed in front of a file, there may be a problem with altering or adding tags once the file is written. If tags are added or existing tags are becoming bigger, the ID3 chunk in a file will need some more space. In the worst case, the whole audio file has to be rewritten, which may be time consuming.

	This is where padding comes into play. When using padding, some additional space is added to the file while encoding to store such added or growing tags. In this case, the file does not have to be ~~rewrittten~~ completely, only this additional padding space is used when tags are added or altered. This makes adding/altering tags a lot more convenient and faster. The only disadvantage of padding is that the encoded files are a little bigger. EAC suggests a padding size of 4 KB. This means that every encoded file will be 4 KB bigger in size compared to a file which does not use padding. So if it is likely that you change or add some tags after the file has been created, then you should leave this option at 4 KB (or fit it your needs). If saving space (e.g. for mobile usage) is more important for you, then you can set this setting to 0 KB.		This is where padding comes into play.
