So I was ripping an audio cd to FLAC using EAC and noticed that the percent compression was a lot higher than all the flac files I have downloaded in the past. As an example, a certain track that is about 4 minutes in duration, when ripped from the original cd, ended up being 12mb in size and 72% compressed. Most of the downloaded flac album tracks are usually about 20-30mb and only 20-30% compressed.
I downloaded the exact same track in flac format and it is 23mb and 46% compressed, which is quite significant. I know there are different compression settings for flac (from 0-8), but from what I read, it didn't seem like the difference could be this huge.
I did a test with both of these flac files and converted them both to wav files, and the sizes are pretty much identical (maybe about 15 bytes off), which seems to me that my own ripped flac file was just truly more compressed than the other with no loss in data/quality.
This is the command line I used in EAC: -8 -V -T "ARTIST=%artist%" -T "TITLE=%title%" -T "ALBUM=%albumtitle%" -T "DATE=%year%" -T "TRACKNUMBER=%tracknr%" -T "GENRE=%genre%" -T "PERFORMER=%albuminterpret%" -T "COMPOSER=%composer%" %haslyrics%--tag-from-file=LYRICS="%lyricsfile%"%haslyrics% -T "ALBUMARTIST=%albumartist%" -T "DISCNUMBER=%cdnumber%" -T "TOTALDISCS=%totalcds%" -T "TOTALTRACKS=%numtracks%" -T "COMMENT=%comment%" %source% -o %dest%
Any ideas on what may be going on here? Is it possible for two flac files of the same song, where one file is twice as big as the other (12mb vs 23mb)? As I stated earlier, most of the download flac files I have are around 25-30mb so to see that this one was only 12mb was a bit shocking. I would appreciate any comments or explanations for this matter! Thanks in advance!
