Just learned my lesson today that it's not because it is a FLAC file that it is always good. I think the most important is to know the source where you get the music. I bought some FLAC song from melodishop.com and now I regret it all. Waste of money. They sell FLAC but apparently their flac file are poor quality and no wonder if it is cheap.
So here is the story. I have a CD of the french singer "Patricia Kaas" album "Mademoiselle Chante..." that I ripped with dbpoweramp as flac.
Melodishop has the same album in Flac version. So I downloaded a couple file to test the quality of their FLAC.
I compared their spectrogram using the program Spek 0.8.2 (Freeware). Obviously the FLAC from the melodishop is a real flac not a flac from MP3 (See first picture of track 01- "Mon Mec A Moi"). The maxima are slightly above 20khz which confirm that the source is not an MP3. Usually a 320kbp MP3 is between 17 to 18KHZ.
Now when I compare the spectrogram to the one I ripped myself directly from the CD (track 01), I obtained the second picture. Maxima 22KHZ and the spectrogram looks more complete.
I played the musics on my computer. The one from melodishop has poor sound quality and grainy compared to the one from the one from the CD which is very clear and well presented. This is not the case of the one track but the entire album. You can hear the difference that is actually huuuge.
Now I raise the question of how do you recognize a good FLAC quality. Both of them are FLAC but the difference is very noticeable (visually and SQ wise) . My recommendation from now is to rip your own CD. That way you are sure you have the quality you are looking for unless you trust the website you are downloading from...
Another song from the same site "Dire Straits" - "Once upon a time in the west". The spectrogram is as follow.
What the heck do I see in this spectrogram ????????? Like I said I just learned my lesson and from now on I won't trust this site anymore.
