Music metallization web application. Is it possible to?

Question

Java

For several months I have been thinking about a project to metallize music. Those. generation of metal versions of music online. However, I have no idea how this can be implemented. I tried to look for articles, guides, videos on this topic, but at most I found the generation of some kind of sinusoidal sounds, volume control and something else. And I need, let's say, to determine which musical instruments are used, which notes, replace them with tracks of heavy instruments ... Do you have any ideas about this? No more thoughts about projects come into my head.

Answer 1

And I need, for example, to determine which musical instruments are used, which notes, replace them with tracks of heavy instruments ..

Well, here's the decomposition..
So, start with the task of "recognizing notes in a solo melody." Already non-trivial.
But in general, most likely you can just throw a distortion. It is even in some libraries. Those. do not reduce everything to notes - effects processors do not lay out the notes.

Answer 2

I don't think it will run. The music is already rendered. Distortion, for example, may lie down, but it will process both the drum and everything else, and you will get an absolutely inaudible mess of dirt.
You can try midi. There must be billions of midi versions of music on the internet. With midi, you can already work with each instrument separately. We pile distortion on guitars, overdrive on bass, shove everything into channels, master as best we can, render, upload.
I somehow see it that way.

Answer 3

I see such a decomposition.
1) transfer of source (mp3/aac/ogg) to pcm format.
2) recognition of rhythm and basic melody and harmony. Isolation of individual instruments and classification.
3) rendering of the drum part and mixing of solo parts with distoshen.
4) pcm -> mp3
Point 2 is the most difficult. They will even pay money for it if the author masters it.
The remaining points of this task are technically solved and are of no interest. They are utilitarian.
