This makes no sense at all. According to this, 256jbps AAC sounds so lossy, the song can't be recognized, and yet our daily usage of such compressions shows this is obviously not the case.
There's some fundamental misunderstandings that are portrayed in this video. You need to be careful and understand that there's a lot more than strict linear response frequency loss when you compress a format. In fact, that isn't even happening when audio is compressed (aside from some bandwidth filtering at the very bottom and very top of the frequency spectrum in most encoders). There tends to be a lot of things that happen. Most popular audio compression formats, such as MP3 and AAC, use a completely different method of breaking apart, storing, and reconstructing a waveform than strictly PCM audio.
An important thing to consider is that this is not precisely the data lost. MP3's and the like are converted into the frequency domain before compressing and quantized to a set number of frequencies. So a 50 Hz wave compressed into a 51 Hz wave (you cannot hear the difference between these two things) when subtracted, will produce a noticeable, subtle sound. That doesn't mean that data was "lost." It means that the data was changed. But this change does not imply an audible change.
..uploaded and recompressed on youtube
Now we take the most compressed version of Suzy and convert it to midi. Trust me, I know what I'm doing.
He purposefully made the first sine wave very loud
Okay, I

I think he made this video after playing around with the audio files for the sayori character file for the DDLC game..just my thought.
now what about compressed compression
so what??? try abx to see if you can hear the difference reliably....interesting, but kind of a waste of time.
Actually it's a lossy digital compression of audio source not audio compression - totally different thing, mate.

Looks like some people in the comment section didn't understand what he actually did with the audio tracks.
Came to know more about audio compression

I like that some of the compressed audio used here is almost usable on its own...

i clicked on this video and then realized this is THE dan salvato of DDLC fame. whoa.
iZotope Ozone 7 has a cool codec preview feature that lets you compare compression artifacts like this to help with mastering
