Spotting Critical Mistakes in EAC Logs

What does it all mean?

Take, for example, the following log, checked with the Log Checker. First we'll show the log checker report, and then we'll discuss the problems identified.

Critical problems

The following points are the critical problems in this log:

Minor problems

Things that aren't definitely issues and would require investigating in some cases, but are possibly not good:

What is a non-audio deduction?

A non-audio deduction is a deduction for any setting which, while required for a 100% log score, does not affect the resulting audio data.

These are the non-audio log checker deductions

Additionally, range rips which can be rescored according to 2.2.10.6. count as having a non-audio deduction.

What does this mean?

FLAC/Log rips with only non-audio deductions can trump those rips which have audio deductions. This means that, for example, a rip which scores 99% due to being ripped in EAC 0.99 can trump a rip with a CRC mismatch, and an EAC 1.0+ rip without the checksum can trump a rip made with the wrong offset correction.

Only a 100% rip can trump a rip with exclusively non-audio deductions.
