Currently, lossless music sharing website appears a lot, so it wouldn't be too hard to find a lossless music albums with popular search engines such as Google, Yahoo!, Bing, ...
But, ever you wonder whether the album that you are, whether lossless quality of it is true that the lossless? or that are just fake files lossless, which means that the file was rip from CD lossless MP3, burn CDs from MP3 files has been to convert the FLAC, ... in fact the file, only the outer skin is FLAC, and quality is just quality of a MP3 files. @@
Thus, we need to have ways to check to see that we are, FLAC file is actually from the source file is original.Here, I would instruct you to check with some of the ways below:
1. Tau Analyzer.
This is the interface of Tau Analyzer
Tau Analyzer allows you to check CD-quality music that you are.
To begin check with Tau, we just put the CD need to check in, then click "Analyze CD"
and wait for the program to work.The results can be obtained:
CDDA: original source.
MPEG: source MP3 or ... :D
Unknown
In addition, to be sure, you can see its spectrum by clicking on the Tab "Spectrum".
Above is the useful features of Tau Analyzer. However, the biggest downside of Tau Analyzer that it can't check each file individually, but only to check CD, sometimes very inconvenient. @@.Thus, we come to the second way, use Audio Checker.
2. Audio Checker.
As mentioned above, Audio Checker allows us to check each individual music files or whole folder, which is very convenient.And here is the interface of Audio Checker.
This program is very easy to use, so that I would not instruct carefully here.After checking, the results will be displayed in the format % + CDDA/MPEG.If 100% CDDA then you can believe it's the original source.If 95 ~ 99%, you should check carefully once again by Spectrum (Spectral sound), the accuracy rate will be higher.
To check the spectrum,you can use Adobe Audition,a famous program of Adobe. To make adobe audition understand flac files you need to add the flac filter in the filter.Download: http://www.vuplayer.com/files/flacfilter.zip
This is the universal sound of MP3 files convert to losslees format but it is. picture of the spectrum there is a line cut in frequency 15Khz
below ,it is the spectrum of a mp3 file,really.Because I use a MP3 file to check :D
P/s: the checking out only the relative nature.When listening to 2 tracks are sometimes combined with your ears, the degree of accuracy would more: D
