No, some music in Wav format is transcoded from lossy formats such as MP3. Although it is displayed as 1411K, the real quality is only the level of the original MP3 format. The more conventional method is Use Adobe Audition to import a WAV format file, and then view its spectrum.

Example: We view the spectrum of the strength of a thousand men’s audio (note that there are 4 small rectangular icons in the middle left position , click the second one to view the spectrum), the upper part is very full

And the spectrum of this oil painting girl

The high frequency is obviously cut across the board, proving that it is actually converted to a lossy format. Fake lossless audio coded, and both are in WAV format

In addition, LoselessAudioValidator can more easily detect lossless music, but there is a certain error. In my use, I once tested 320Kmp3 as lossless Situation

Of course it is also a good idea to practice your ears...
