But again, I can't speak to the technical reasoning for this someone else will have to chime in. More is being done in the former case (and internally tested to not mess up the moving of the audio data). I don't know the technical details personally, but my educated guess would be that it would always take longer to "rewrite" the existing files to contain new tag data in addition to the audio data than to simply copy/duplicate the file itself. Mp3tag, 12 FLAC files, 264 MB total: 73 secondsĪs it often does, Mp3tag got through the first six files pretty quickly, but then it bogged down on file seven and after, which took up most of the time.

For example, I just now added the same 95 KB album art to these two sets of files lacking album art, all of which have been on my hard drive for several months so there is no prior caching to influence the results:ĮZ CD Audio Converter, 12 FLAC files, 345 MB total, transcoding to ALAC + adding album art, 1 thread: 17 seconds It is actually far faster for me to load the FLAC files into EZ CD Audio Converter, add the album art, and transcode to ALAC. While the source and destination drives are the same WD green drive, this is still inexplicably slow and far slower than simply duplicating the files. This is happening again with Mp3tag 2.57 on my new build, which is an i5 4670 with 16 GB RAM.

#ARTWORK EZ CD AUDIO CONVERTER UPDATE#
It might take a minute or two to update a dozen files 20-40 MB each. I've been using Mp3tag for several years, and for as long as I can remember, writing 100 KB album art to FLAC files has been very slow if the files must be rewritten.
