thx very helpful
You’re welcome my friend!
This is awesome! Just a heads up, the "Bake Sound to F-Curves" is now under Channel in version 3.6.
True! I hand't noticed that they changed it, thanks for the update mate!
4.1 Version of Blender the is under Channel, then Sound to Samples at the bottom
Excellent bro thank u so much
You're very welcome mate, cheers!
This was a great tutorial. I’ve been wanting to learn this for a long time, thank you!
You're very welcome!
Really helpful, tysm!
You are very welcome!
Cant believe I've never noticed the option to choose frequency! Thank you good man!
Yeah it’s kinda right there 😂 glad to help mate!
good
👌🏻👌🏻👌🏻
Let's say I want 100 bars, and still not go below 20 Hz? The equation showed doesn't seem to address that:
Let's say the equation we want to satisfy is Freq_h = Freq_l * Base^Steps, where...
- Freq_h is the highest frequency we want
- Freq_l is the lowest frequency we want
- Base is the base of the exponential (what we want to find out)
- Steps is the amount of bars we want to render
The idea is to find the exponential base to use in the equation:
Base = (Freq_h / Frequ_l) ^ (1/Steps)
An example:
Base = (16K / 20) ^ (1/100)
= 1.069... (nice)
So we would use the following formula to find each frequency:
Freq_s(x) = 20 * 1.069...^x, where x is the step we are interested in.
For instance, if we compute the 100th step:
Freq_s(100) = 16000, which is what we wanted.
Hope this helps!
Hey! I don’t understand what’s the problem you are trying to solve but knock yourself out! 100 or 1000 bars is the same equation if your first bar starts at 0 which is how sound visualizers would work. If you’re trying to find some specific situation for your project, then obviously you need different math. Cheers!
@@Dude_Blender Hmm, sorry if that was not clear! The equation shown doesn't let you chose N bars between a lower bound and higher bound frequency, because your exponential base is a constant = 2. This means that if you want 100 bars, the lower frequencies will have lower than 20Hz, which is NOT how sound visualizers work. You want more bars between 20Hz and 16KHz. The way to do this, as my comment shows, is to figure out the base of the exponential.
If you display frequencies below 20Hz, people won't hear what they see, so of course you don't want that for typical visualizers.
@@pladselsker8340 oh ok, so you want to skip the 0-20hz range? Well I guess if you’re using 100 bars it makes sense, although, would you set up 100 bars? Most of the time I’d figure out ways to work less while keeping the general idea look good awesome. I don’t know if an audience would appreciate the 10x extra work of making so many bars as opposed to just doing it with 10. But yeah if you’re doing many bars and therefore would want to skip the inaudible low range then for sure it’s a different formula, good point! Thanks!
