Topic: Guide: Using Spectroanalysis to Check .FLAC rips

So, you found a .flac file floating around the internet and want to make sure it's not a transcode(a file that has been converted from a lossy file, such as .mp3, .m4a, etc., to .flac). How do you do that to make sure you're not uploading(or downloading) shitty files? It's really easy, you just need a program that can spectroanalyze the files.

This is a freeware program which enables you to do such a thing!

Simply open one of the files of your .flac rip in this program

and it should look like this:

See how there is barely any blackspace above the blue? (this will make more sense in a moment)  That is confirming that there has been no loss of quality with the compression of this file.

This is what a 320 CBR .mp3 file looks like:

The compression has forced the kHz to drop below 22, and you can see that very thin layer of blackspace.

Here is a v0 .mp3 file:
