Harmonics and envelope give sound... | show 🗑
|
||||
show | most basic sound, simplest type of wave you can have. have flute-like character. No harmonics. (flute has a sound that contains very few additional frequencies)
🗑
|
||||
show | ...sine waves superimposed on others.
🗑
|
||||
complex sounds have... | show 🗑
|
||||
show | what overtones are called in pitched sounds like musical notes. multiples of the fundamental.
🗑
|
||||
fundamental frequency can also be labeled as... | show 🗑
|
||||
show | 2X the fundamental
🗑
|
||||
third harmonic | show 🗑
|
||||
sawtooth wave | show 🗑
|
||||
show | it all odd numbered harmonics are present at the same relative amplitude. Skip every other harmonic frequency (1, 3, 5, 7, 9, 11....) still sounds kinda bad
🗑
|
||||
Why can't you make a square wave with all even harmonics? | show 🗑
|
||||
complex waves | show 🗑
|
||||
show | harmonics can be called overtones, but not all overtones are harmonics
🗑
|
||||
How do we differentiate 'voices'? | show 🗑
|
||||
show | the combination of all the elements of your vocal tract; vocal cords, sinuses, oral cavity, etc.
🗑
|
||||
spectrogram | show 🗑
|
||||
show | ...different harmonic content. Those high frequencies are important in allowing us to differentiate between the sounds in voices.
🗑
|
||||
show | high frequency sounds that are important to keep so we can differentiate them
🗑
|
||||
show | You're left with unintelligible, muffled voices
🗑
|
||||
show | musical term for harmonic character of different instruments
🗑
|
||||
show | pitched sound and noise based sounds
🗑
|
||||
pitched sounds | show 🗑
|
||||
show | indistinct fundamental frequencies and overtones. drums and cymbals and any other non pitched rhythm instruments. Have frequencies that aren't multiples of the fundamental, so they're called overtones, not harmonics
🗑
|
||||
What determines our perception and recognition of a sound? | show 🗑
|
||||
show | term used to describe the change that takes place to sound over time. How a sound stars, (suddenly or gradually) decays, and ends
🗑
|
||||
What does envelope apply to? | show 🗑
|
||||
audio tracks on digital editing softwares are a... | show 🗑
|
||||
show | attack, decay, sustain, release
🗑
|
||||
show | energy enters the piano string, amplitude grows
🗑
|
||||
show | point where sound (amplitude) is dying away the most rapidly, a little arbitrary and hard to decide for absolute sure
🗑
|
||||
show | amplitude changes very minimally
🗑
|
||||
release | show 🗑
|
||||
dynamic range | show 🗑
|
||||
show | ...each part of the chain has a measurable dynamic range, and the overall system also has a measurable dynamic range
🗑
|
||||
noise floor | show 🗑
|
||||
show | ...the lower the noise floor
🗑
|
||||
clipping | show 🗑
|
||||
clipped flattened tops represent... | show 🗑
|
||||
show | ...to keep signal above the noise floor and below clipping from source to output
🗑
