I just had a dream last night of an ingenious software to fix the loudness war of music and restore the cut peaks.

The explanation will become a little nerdy:

1. You need a vinyl release of the same album that came out on CD or DVD.

2. The software scans both album releases. We know that most vinyls have got full dynamic range and thats crucial.

3. Two things will be scanned. First: The waveform. The optical waveform of the vinyl will be adjusted to the CD. If the software finds similar patterns, the graph will get optimised and streched/morphed to look like the CD (will be important later), as vinyls are never playing in designated speed, due to the hardware. Speed and sound colour of vinyls are inherently different to the original master.

4. A second similarity scan will be done. This time, even though the sound colour is different, the smart software figures out which instruments are the same to the CD. It will decrypt the „colour scheme” by finding same melody lines and pitch it to the same level. But this is a little more complex to realise than it sounds. The entire algorithm needs to get matched here. Complex scans figure out similarities in colour and speed.

5. Now the software notices that some instruments are louder, because vinyls aren’t over-compressed. This time the CD gets adjusted. The samples that sound the same now become quieter on the CD that were compressed to a too loud level. It gets aligned to the level of the vinyl, so that every single volume ratio is restored. The vinyl was the reference for a proper volume ratio. I think the CD will need to get an intelligent refining after this process, because over-mastering sometimes leads to clipping and distortion in the upper regions and needs a smoothing algorithm. Also mono-bass-to-stereo-bass recognition is necessary.

What do you think? Realistic idea reverie? Feel free to steal my idea. I just want to save my favourite music, ’cuz DR is life.

I'm quite sure the final mix gets destroyed before it's pressed to vinyl or CD. I don't think vinyl recordings automatically have a high dynamic range

Not true. They do have full dynamic range. Don’t think but listen. Import to Audacity and you will also see the proper waveform.

Another example is DVD videos. Eluveitie — Thousandfold is an example. CD sounds like shit but music video with PCM stream on Nuclear Blast Clips Vol. 1 sounds perfect. There do exist unaltered versions.

I don't think they do a compressed version for CD release and Dynamic version for Vinyl

Assumptions can be dangerous when you don’t investigate my friend.

Is the loudness war even a thing anymore, given the move to streaming, and the fact that most of those platforms now have volume normalization?

Let me have some of whatever you were smoking.

I know a way to fix the loudness war: Play the music more quietly.

Do i get a Nobel prize now?

Claiming your assertions are correct when you provide no evidence is dangerous my friend.

I threw away 74 cd's last year that i purchased new. [i am still replacing my old record collection that i sold off, around 2004]

Upon playing, when they did not sound right, i ripped them onto the computer one-by-one and took a look at the wave forms; they were all without transients.

I then went onto the discogs site and purchased the same cds again, this time second-hand copies, most pre 92, and only releases marked [not] remastered, and they were all good and sounded like the records.

It was an expensive exercise however, as all I kept from the 74 was the jewel cases, the rest went in the bin.

what kind of trigger material are you writing here? Deteriorating binary stored on an audio cd resulted in flattened transients?

Can someone please ask this guy what's going on?
