FLAC file confusion

post #1 of 5
Thread Starter 

I have developed a more greater interest in my music by upscaling from apple earpods to a full stereo at home and wanted to also upgrade my mp3's to FLAC. I have been getting these files and have heard that some of these files may be "fake" flacs. So I did some research and found that flacs surpass or cutoff at 22 kHz on a spectrogram, but some of my flac files cutoff at 21 kHz. Are these flacs real or just dubbed up mp3 files that have been converted to flac. If I'm missing something can someone please correct me.

Hi,

 

I'm not going to answer your question, but you may find this pretty useful in order to get the best sound quality.

 

If you want to get the best sound quality out of your headphone (or speaker) rig, be sure of picking the best recordings out there. You could read about Chesky Records, Harmonia Mundi, Telarc, and many other audiophile recording labels.
Unluckily, while it's easy to find classical, jazz and acoustic audiophile recordings it is not that easy to find well recorded music of other genres.

 

A good way of finding nice recordings is using a Dynamic Range Meter, or using this amazing database:

Dynamic range over 12 is pretty necessary for high quality reproduction.
Most modern music is really compressed and dynamic range under 6 is very common this days.

 

Recording quality have a much bigger impact on sound quality in comparison with file quality.

There isn't a big difference between a good transcode mp3/320kbps and a loseless Flac file. But there's a HUGE difference between "Spanish Harlem" by Rebecca Pidgeon (Chesky Records) and "Born To Die" by Lana del Rey, no matter if you have a Rebecca's song in mp3/320 and Born To Die in FLAC format.

 

Best Luck!

The only way you'd end up getting fake FLACs transcoded but not in any way improved from compressed files is when you want music for free from unreliable sources (not that they all are).

I appreciate the extra info but the only thing I really want to know is if this 21 kHz cutoff makes it a fake FLAC file, thank you though.

Not necessarily - if the track gets up to 21khz then chances are it didn't come out of a compressed file. My point was only that if you were purchasing FLAC albums online then there's no need to worry if they're really uncompressed FLAC.
