When you play two notes a wide interval apart on the piano - like a 5th, you hear two distinct pitches. But if you play two notes really close to each other - having a frequency of less than about 30 Hz between them, like a semitone - then we don’t hear two distinct pitches. Instead we hear the a single note at the average frequency, but with a volume which goes up and down over time. This variance in volume is called a ‘beat’ - and creates a ‘wah-wah-wah’ sound. And these beats happen at the difference in frequencies between the notes.
Finally I understand those weird artifacts that pop up when I use the whammy bar of my guitar on overtones. it was beating all along! great video!
i could hear ut from the first change, because i've good speakers hear, you can hear the wavelength, and in the first change you can clearley hear the slow wave lenght and changing more eventually going up more and more
This is music for my ears! Thank you! And finally I've understood why lots of violins together sound so velvety while one alone sounds raspy.
Excelent video series!
All your materials are gold, hopefully future generations can appreciate!
This is so good! Thanks for the great content
All of youre videos are amazing and informative a f
amazing! i love your channel!
Such an interesting tutorial. Thank you again WTB...
50 : 51 (510/500Hz) is off by 34.283 cents
love your vidoes mate!
That's how those “Weow” guitars work then, huh?
The difference between 500Hz and 501Hz is 3.45901 cents
Ques:
You can hear missing fundamental as soon as beat frequency is high enough.
If A 1 = 27.5 hz @ Which Frequency does BPM begin ?
how do i generate the sine waves of a sound file that i have and then develop a mathematical function for the sin wave ?
I hope you get more views.
Well done. I didn't quite get the second order beat sound at the end. Maybe you could expand this topic in a second video.
