Every sound is SINE

Every sound is made from an infinite number of sine waves. You could say that we all speak sine language.

I always knew as a fact that sound is made up of waves and vibrations, that's what we're taught... but this has given me the understanding like absolutely nothing else, easily becomes one of my favorite videos of all time, Mind blown.

6:47 the way the bells could be rounded off into individual bell strikes literally sounded like magic

2:44 as soon as it said "Square Wave" I almost had a heart attack, lol. I feel like my entire knowledge of music production has been unlocked from trial mode.

5:42 the 3 sine waves talking hit me like a semitruck

6:37 this part is actually banging like holy shit

New fear unlocked: vocals with 3 sinewaves

As someone who spent years suffering through wave theory, Laplace transforms, and Fourier series I greatly appreciate this video

At 7:12 you say that what ultimately hits our eardrums is a single sound wave. This is true, but the next step, which I think is fascinating, is that your inner ear splits the sound wave back into its component frequencies, and the amount of each frequency is what gets sent to the brain.

I put my day on hold when a new video comes out. Also, I was writing software one time for a machine which needed a buzzer sound. Customer supplied a buzzer noise which even at the smallest file size was too big for the chip to store. Instead, I did an FFT to find the harmonics and amplitudes of the sound, then wrote a few lines in the software to play corresponding some waves back. Saved a ton of space. Then realized I had to explain to the customer why it's not just a drag and drop to try new buzzer sounds.

5:13 i want a full version of this! it sounds like a SpeedCore/EDM song! i love it!

this is one of the best videos on audio i've ever watched. it's the first one that actually follows the golden rule of "show, don't tell", and that makes all the difference. damn your channel is a gold mine.

The car alarm at the end is hilarious.

I'm kind of impressed that you can approach topics like FFTs without even mentioning FFTs!

Just amazing! It's so cool to see all the different waveforms broken down like that. I had no idea that different waveforms are created by harmonics (made up of varying frequencies, amplitude and phases). I love the part at the end! I've done that many times playing around with knobs in LMMS. Very fun to learn though!

Wow! My not only was my mind blown in this video, but also my eardrums! Outstanding works there Posy!

This video quality is something I expect from a channel with at least half a million subs, not 30k. I’ve subscribed and look forward to seeing more!

So well done!! Thank you for this!!! The speech as three sine waves was mind-blowing.

Following up the two first videos, I (a sound designer and musician) arrive here. Already a subscriber, and now I'm blown away. You are a creative genius, and I'm so happy I found your channel...

This is so good, Posy. Excellent visualization!
