What is Granulizing?
« on: February 18, 2016, 11:33:19 pm »
I recently saw Maor Levi post something about it but I didn't know what it was he something about putting it on vocals? What I heard was really sweet & also he used it on FL so I was wondering if it was only for FL?

Do some google search, as far as i can tell and the little bit of research i've done myself, i'd compare it to grains of sand.
Josh Huval: Honestly, the guys who are making good art are spending their time making it.

I might be wrong but, what I'm reading is that i's basically time stretching with no change in pitch...tho I don't know how Maor mixed a vocal almost into a build like lead in of itself

Here's the link to what I found what granulation might be

Here Maor Levi showing Granulization

https://www.facebook.com/MaorLeviOfficial/videos

I can't get the direct link but their titled on his videos so I hope you can find granulization & see what I mean btw it's super cool

This is how they're titled

"This is too much fun"

"Granulizing is the future"

when you play a sound, it's a series of individual grains played in succession. imagine each individual grain is a snapshot of the sound - it will play the frequencies of the sound at that given point in time. when you stretch a sound but keep the pitch the same, the reason why it has that metallic resonance type sound (called an audio artifact) is because the sound is trying to not leave space (silence) inbetween the grains. if you stretch a sound waaaaaaaaaay out, you can really hear each individual grain of it.

So in the digital audio theory, sounds are made up of samples, not samples like taking from other songs or sound sources but basically small pieces of a waveform that have different values. Granulizing is taking small groups of samples essentially and chopping them up. So if you stretch something granularly it doesn't stretch the sound as a whole but rather as "grains" which are those tiny pieces. Ableton's sample editing mode called texture is a great example of granulizing, the size knob indicates how big the grains will be and the flux I'm pretty sure is how the grains interact when stretching or pitching the sound but don't quote me on the last part. Hope that helps!  :D

This really interests me. How does Paulstretch stretch samples without creating artefacts?

Some method of interpolation between the sample points.

I found this: https://github.com/paulnasca/paulstretch_python/blob/master/paulstretch_steps.png

So looks like it randomizes the phases of the individual frequency components for each small block, and then combines the blocks at longer intervals. I guess the effect is that any transients in the blocks are lost, which makes the transitions smooth, but the frequency content is the same.
