Excellent content...consider me subscribed! Here's a fun fact: the brain is awesome and can actually fill in the blanks even if the fundamental is completely missing...it can generally perceive the fundamental just from listening to the harmonics alone. Some plugins use this phenomenon of psychoacoustics to help create the impression of bass (even when the speakers are physically unable to reproduce the low frequency of the fundamental itself) by creating the harmonics instead, which are generally multiples of the fundamental frequency. The only problem with this is that the bass then becomes "bass you can hear" rather than "bass you can feel". I love the brain. It's so frickin' awesome!

I am currently doing my masters in Aerospace and have been producing music for around 5 years.. This video just helped me better understand Fourier Series and understand audio production better!!! Thanks a lot!

Man, I am so appreciated for what you are doing. I currently am just a bedroom a DJ, but learning about all these sound designs and fundementals got me much better at what I am doing since i have much more control over what is going to happen, plus i am so sure i will knock your door soon to get into one of your programs to learn to be able to produce myself. I really really like your scientific approach rather than just tweaking some knobs! Stay as you are big man!

Thank you very much!

Nice use of the Awesome 3 piano riff there. 😎 Awesome explanation too. 👍

Excellent ..Thanks for posting!!✌

Wow! concepts that we are struggling with, you demonstrate them with such comfort? Thank you.

Great video - simple and straightforward! BTW double-click on Spectrum or EQ8 to make the spectogram much bigger and easier to present :)

Thanks man ! clean job ; learned a lot was really cool to watch

Very interesting video! 👍 Which program do you use for screen recording please? I need one 😁

friend you explain everything well, thank you, today I found your channel is super cool!

thanks oscar!!!

Great video.

Great video, straight to the point no bs ! subscribe👍🏾

Wonderful, thank you.

Wonder if you could clear something up for me? Often when analysing sounds (e.g within a drum kit) the reading is quite ambiguous and there isnt a clear fundamental, so is the key of a sound ALWAYS the first peak, or is it sometimes the highest peak? What is the 'rule'? I often get a reading on the spectrum analyser where the first 'leftmost' peak, lets say at 100hz, is several Db lower than another peak at a higher frequency, lets say 1khz. In this scenario which of the two peaks do you use to determine the key? Is it the very first peak (the lower Db of the two, the fundamental), or is sometimes the peak with the highest Db and higher freq?

im confused on the piano example. is it the most left frequency even if it has hte lowest amplitude?

❤ merci !

5:24 Thanks (was listening on my headphones 😅) Edit: you got my at 6:14 though :P

Hello im.trying to have an oscilator in any synth (wavetable, serum, whichever vst) to be able to play the same note that i can choose regadles of the key i press on the keyboard, does anybody know how can i do that?

But how harmonics are produced by the vocal folds at the same time

Still better singer than most of the famous singers :P

Harmonics and overtones are different
