Revision as of 11:30, 23 November 2011

Exact Audio Copy provides numerous placeholders to be used when invoking a command-line encoder and when naming output files.

Beginning with EAC version 1.0 beta 2, the naming scheme for placeholders was revamped, necessitating that users moving to this new version revise their command lines. Both old and new lists of placeholders and their meanings have long been available in the official EAC FAQ and in several of the Hydrogenaudio Knowledgebase’s own Guides; however, there was no easy way to look up values and to compare them between different versions.

Moreover, confusion can arise from the fact that versions of EAC prior to 1.0b2 used different placeholders for naming the output file compared to those for passing to the external encoder. These two sets of placeholders do not correspond, but they are similar enough to get mixed up.

For these reasons, as well as for general convenience and ease of use, this page intends to simplify the process of using (or comparing/substituting) placeholders, by collating all of those listed by the EAC FAQ into a single table.
