Is there an easy way to detect for an existing FLAC file at which level (1-8) it is encoded?
Even better would be a search for all flac files in a certain directory that are encoded in, say, level 5.
The reason for this question is that I am running out of hard disk space and would like to use level 8 to get the smallest possible files. However, converting all my flac files would take many days, so I would prefer to spot the non-level-8 ones.
