Difference between wav and mp3 Part 2
Lossy sound?
In the case of a WAV file, if you play the exact same WAV sound source file with the sound waveform reversed and the original waveform file together, you won’t hear anything.
So by applying Audition phase inversion to a WAV file and playing it at the same time as the MP3 version file, I tried to extract the sound that is irreversibly compressed and can be heard in WAV but not MP3, commonly known as ” Lossy Sound “. !!
0.03 Original WAV sound source (①)
0.08 Inverted WAV sound source (②)
0.15 ① and ② (silence)
0.22 MP3 sound source (③)
0.28 ② and ③ (Lossy sound)
It flows in the order of.

I’m sure there are people who think this lost sound is not a big deal, and people who think it makes a big difference.
Personally, when I listened to Lossy Sound, I thought that the thickness and sound of the sound was considerably lost in MP3.
The music used in this check was a song with a high range overall, so if you want to compare it to music with a strong mid-low range, check out the video below!

By the way, the response from the listening comparison test was
①WAV → ②MP3 → ③MP3!
To be honest I heard it many times
and I finally thought it was different, but when I heard Lossy Sound
