Difference between wav and mp3

I heard that there is a difference in sound quality between WAV and MP3, but how much is it really different?
Does anyone think so?

Even if you theoretically know that a WAV file is a lossy compressed file, it is an MP3 file, but it seems that few people really compare the WAV file and the MP3 file of the same song.
Lossy compression is a compression method that can significantly reduce the amount of data, but when compressed data is decompressed, it is not fully restored and data loss (corruption) occurs.
This time, we will do a simple check so that you can understand the difference between WAV and MP3 more deeply by learning not only the form and theory, but also the sense of hearing!
Even if it says verification, just listen and compare!
I hope you have read this article and used it as a basis for deciding whether to use WAV or MP3 in the future.
From the meaning of the terms to the operation procedure, we will explain it smoothly with pictures.

Difference between WAV and MP3
For those who don’t know what the different format of WAV and MP3 is, I will explain it in words first.
If you already know, go to the “Listening Comparison Test” below.
In short, a
WAV sound source is a format that preserves the same sound quality as an uncompressed recorded state.
The sound quality is good because it is not compressed, but it also has the disadvantage that the file is very heavy.
Secondly,
MP3 is a file that is significantly lighter by removing only the sounds that are inaudible to humans in the WAV file to lighten the sound source file that is too heavy for WAV.
By the way, for reference, the size of the same WAV and MP3 file
it’s 9.2MB, which is less than 1/4 of that, while WAV is 41MB.
The file is very light, but let’s check how much sound is gone.
Comparative hearing test
In fact, I prepared the MP3 version and the WAV version of the same song.
If you say this is MP3 and WAV first, you may hear WAV better due to biases, so first try listening to the sounds without saying which one …
Play the same phrase from the same song three times.
Of those three times, we will answer after the final summary if each was MP3 or WAV.
People with very good hearing can hear it because it only cuts out sounds that humans shouldn’t be able to hear, but it doesn’t matter if they can’t be heard.
